Communication networks and systems for power utility automation - Part 7-410: Basic communication structure - Hydroelectric power plants, steam and gas turbines - Logical node classes (IEC 61850-7-410:2026)

EN IEC 61850-7-410:2026

This part of IEC 61850 specifies the logical node classes for use in the domain of hydroelectric power stations, steam and gas turbines.
This IEC61850 domain information model standard utilizes the existing Logical Node (LN) classes defined in IEC 61850-7-4, Basic communication structure – Compatible logical node classes and data object classes where possible, while defining new and extended domain specific LN classes to provide the necessary data objects for application to functions and systems in the domain of hydroelectric power stations, steam and gas turbines. The domain information model includes the interface towards a central operator centre’s control functions.
The Scope of this document, related to steam and gas turbine specifics, is limited to overall control functions and generator and turbine control functions. For hydroelectric power, the scope includes the entire power station automation system.
Edition 3 is intended to form a basis for extensions in local implementations. Such extensions may be defined in profiles. Many of the Logical Nodes defined in this document are designed to be suitable for use in domains beyond the scope of hydro power plants and steam and gas turbines. A suggested structure of the Logical Nodes into packages for integration with other domains is provided in Annex G (informative), Migration of this document to the future edition of IEC 61850.

IEC TS 60870-5-601:2015(Main)

Telecontrol equipment and systems - Part 5-601: Transmission protocols - Conformance test cases for the IEC 60870-5-101 companion standard

IEC TS 60870-5-601:2015(E) describes test cases for conformance testing of telecontrol equipment, Substation Automation Systems (SAS) and telecontrol systems, including front-end functions of SCADA. The use of this part of IEC 60870 facilitates interoperability by providing a standard method of testing protocol implementations, but it does not guarantee interoperability of devices. It is expected that using this part of IEC 60870 during testing will minimize the risk of non-interoperability. The goal of this part of IEC 60870 is to enable unambiguous and standardised evaluation of IEC 60870-5 companion standard protocol implementations. The guidelines and conditions for the testing environment are described in IEC 60870-5-6. This new edition includes the following significant technical changes with respect to the previous edition:
- resolving ambiguities and inconsistencies between IEC 0870-5-101:2003 and IEC TS 60870-5-601:2006;
- enhancements and optimisation of test cases which are needed to prove conformance with IEC 60870-5-101:2003.

IEC TS 61850-80-6:2026(Main)

Communication networks and systems for power utility automation - Part 80-6: Using IEC 61850 for communication between power system automation equipment and control or maintenance centres

IEC 61850-80-6:2026, which is a technical specification, provides a comprehensive overview of the various aspects that need to be considered while using IEC 61850 for information exchange between power system automation equipment and control or maintenance centres or other system level applications. This document:
defines use cases and communication requirements that require an information exchange between power system automation equipment and control or maintenance centres;
describes the usage of the configuration language of IEC 61850‑6;
gives guidelines for the selection of communication services and architectures compatible with IEC 61850;
describes the engineering workflow;
introduces the use of a Proxy/Gateway concept;
describes the links regarding the Specific Communication Service Mapping (SCSM);
defines the abstract conformance test cases that build the basis for the conformance test procedures elaborated by the UCAIug Testing Sub Committee.
This document does not define constraints or limitations for specific device implementations. There is no specific clause for cyber security, which is tackled when it is necessary. The model for IEC TS 61850-80-6 provides security functions based upon the security threats and security functions found in IEC TS 62351-1 and IEC TS 62351-2. This document touches on several security aspects with the following basic assumptions:
Information authentication and integrity (e.g., the ability to provide tamper detection) is needed.
In case of operational issues, encryption (to achieve confidentiality) is optional. This typically applies for GOOSE and SV messages in the power utility automation system LAN.
End-to-end information authentication and integrity methods, regardless of information hierarchies, need to be provided. The typical method to provide this security function is through some type of information/message authentication code. IEC 62351-4 and IEC 62351-9 describe how authentication and integrity is achieved for IEC 61850-8-1. IEC 62351-4 provides means to ensure end-to-end data integrity through Proxy/Gateways.
Beneath information authentication and integrity, information availability is an important aspect for telecontrol. This document provides redundancy architectures to enhance the availability of information in control and maintenance centres

Communication networks and systems for power utility automation - Part 90-19: Use of Role Based Access Control (RBAC) with IEC 61850

IEC PAS 61850-90-19:2026 document takes over the IEC 61850 data model specific definitions such as the definition of permissions and their assignment to roles from IEC 62351-8.
The general requirements for Role-Based Access Control (RBAC) are defined in IEC 62351-8. This part of IEC 61850, which is a Publicly Available Specification, applies those requirements to the IEC 61850 environment, including the RBAC modelling considerations, the impacts on IEC 61850 models and protocols, and the resulting engineering process requirements.
Additionally, the binding of permissions to objects is defined to allow an interoperable implementation regarding the semantic of roles. This is achieved by an assignment to unique data objects based on the SCL description. Note that for this, IEC 61850-6:2009+AMD1:2018+AMD2:2024 is a prerequisite as it defined a unique identification of objects in SCL.

Power systems management and associated information exchange - Data and communications security - Part 8: Role-based access control for power system management

IEC 62351-8:2026(Main)

IEC 62351-8:2026 is to facilitate role-based access control (RBAC) for power system management. RBAC assigns human users, automated systems, and software applications (collectively called "subjects" in this document) to specified "roles", and restricts their access to only those resources, which the security policies identify as necessary for their roles.
As electric power systems become more automated and cyber security concerns become more prominent, it is becoming increasingly critical to ensure that access to data (read, write, control, etc.) is restricted. As in many aspects of security, RBAC is not just a technology; it is a way of running a business. RBAC is not a new concept; in fact, it is used by many operating systems to control access to system resources. Specifically, RBAC provides an alternative to the all-or-nothing super-user model in which all subjects have access to all data, including control commands.
RBAC is a primary method to meet the security principle of least privilege, which states that no subject should be authorized more permissions than necessary for performing that subject’s task. With RBAC, authorization is separated from authentication. RBAC enables an organization to subdivide super-user capabilities and package them into special user accounts' termed roles for assignment to specific individuals according to their associated duties. This subdivision enables security policies to determine who or what systems are permitted access to which data in other systems. RBAC thus provides a means of reallocating system controls as defined by the organization policy. In particular, RBAC can protect sensitive system operations from inadvertent (or deliberate) actions by unauthorized users. Clearly RBAC is not confined to human users though; it applies equally well to automated systems and software applications, i.e., software parts operating independent of user interactions.
The following interactions are in scope:
– local (direct wired) access to the object by a human user, a local and automated computer agent, or a built-in human machine interface (HMI) or panel;
– remote (via dial-up or wireless media) access to the object by a human user;
– remote (via dial-up or wireless media) access to the object by a remote automated computer agent, e.g., another object at another substation, a distributed energy resource at an end-user’s facility, or a control centre application.
While this document defines a set of mandatory roles to be supported, the exchange format for defined specific or custom roles is also in scope of this document. This is achieved by defining two different encoding approaches to handle the definition of custom roles, either based on specific permissions or based on constraints to existing permissions. The definition on handling custom based roles was started in IEC 62351-90-1 and taken over into the IEC 62351-8:2020. Moreover, additionally to the definition of custom roles based on associated permissions, this document also includes options how to assign permissions to objects in a general way. Referencing documents will provide a mapping to a concrete data model to ensure an interoperability for standard roles used in different data models as well as for custom defined roles. Referencing documents might be standards such as IEC PAS 61850-90-19 or IEC 60870-5-7:2025 or also definitions by an operator.
Out of scope for this document are all topics which are not directly related to the definition of roles and access tokens for local and remote access, especially administrative or organizational tasks, such as:
– definition of usernames and password definitions/policies;
– management of keys and/or key exchange;
– engineering process of roles;
– assignment of roles;
– selection of trusted certification authorities issuing credentials (access tokens);
– defining the tasks of a security officer;
– integrating local policies in RBAC.

Communication networks and systems for power utility automation - Part 7-410: Basic communication structure - Hydroelectric power plants, steam and gas turbines - Logical node classes

IEC 61850-7-410:2026 specifies the logical node classes for use in the domain of hydroelectric power stations, steam and gas turbines.
This IEC61850 domain information model standard utilizes the existing Logical Node (LN) classes defined in IEC 61850-7-4, Basic communication structure – Compatible logical node classes and data object classes where possible, while defining new and extended domain specific LN classes to provide the necessary data objects for application to functions and systems in the domain of hydroelectric power stations, steam and gas turbines. The domain information model includes the interface towards a central operator centre’s control functions.
The Scope of this document, related to steam and gas turbine specifics, is limited to overall control functions and generator and turbine control functions. For hydroelectric power, the scope includes the entire power station automation system.
Edition 3 is intended to form a basis for extensions in local implementations. Such extensions may be defined in profiles. Many of the Logical Nodes defined in this document are designed to be suitable for use in domains beyond the scope of hydro power plants and steam and gas turbines. A suggested structure of the Logical Nodes into packages for integration with other domains is provided in Annex G (informative), Migration of this document to the future edition of IEC 61850.
This third edition cancels and replaces the second edition published in 2012 and Amendment 1:2016. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) New concepts and constructs for modelling of large power generation;
b) Addition of new Logical Nodes to cover systems and details of the power generation domain previously not modelled in a sufficient way;
c) Review of existing Logical Nodes concerning structure, use of Common Data Classes and naming;
d) Fixes and improvements of some names and descriptions of Data Objects;
e) Improvements of the structure and enumerations within the Domain Logical Nodes;
f) Addition of new Logical Nodes with respect to maintenance and supervision functionality;
g) Updating of Logical Nodes for PSS functionality (LNs: APSS, APST and APSF) reflecting the updated PSS standard IEEE 421.5:2016;
h) Incorporation of Amendment 1, including among other things the Group E Logical Nodes;
i) Resolutions to all known UML Issues related to IEC 61850-7-410;
j) This 3rd edition is autogenerated from the UML file;
k) Upon publication the updated IEC 61850-7-410 NameSpace will be made available as a Code Component on the TC57 web page.
In the Edition 3 of this document, a new modelling approach is applied. In order to achieve greater efficiency and harmonization of the IEC 61850 information model by streamlining the Namespaces it is divided into, the structure of the latest revisions of the Namespaces related to the power generation domain, aims to:
– share common concepts, approaches, and models in the generation domains,
– increase the modularity of the model itself and enable its extension.
This edition hence introduces a new modeling approach, which is further explained in Clause 5. The pillars upon which the new approach is founded are as follows:
– a layered architecture for the power station model, in accordance with the control hierarchy concepts defined in IEC 60050-351-55;
– a comprehensive review of the models considering the approach outlined in IEC 61850-7-420:2021, aimed at harmonizing fundamental concepts in the power generation domain;
– a systematic alignment with the concepts outlined in IEC 61850-7-500:2017.
Specific aspects typical of the large power generation domain are also addressed in the present document. The relationship between concepts described in this document and the ones of related standards can be found in Annex B and Annex C.
In addition to this objective, Edition 3 provides c

IEC TR 61850-80-5:2026(Main)

Communication networks and systems for power utility automation - Part 80-5: Guideline for mapping information between IEC 61850 and IEC 61158-15

IEC 61850-80-5:2026, which is a Technical Report, specifies the mapping framework for building and configuring a system using both IEC 61850 and IEC 61158-6-15 (Industrial communication networks – Fieldbus specification, CPF Type 15, Modbus) protocols by utilizing gateways between IEC 61850 and IEC 61158-6-15 IEDs / subsystems. The objective is to enable operational run-time data exchange among these IEDs / subsystems, and to automate the configuration of a gateway as much as possible.
Please note that for the purposes of this document, "Modbus" is used to represent both serial Modbus (Modbus RTU) and IEC 61158-6-15 (Modbus TCP).
Within the capability of each protocol, some configuration attributes (IEC 61850-7-3:2010 and IEC 61850-7-3:2010/AMD1:2020 attributes with functional constraint CF) are also mapped in addition to the operational real-time data.
The frameworks specified in this document are based on the published standards and do not make any proposed changes to IEC 61850 or 61158-6-15. This standard does not specify any framework for an IEC 61850 IED to directly communicate with a Modbus IED and vice versa, except through a gateway.
This document does not mandate which data items that a particular IED will be supporting, regardless of whether the implementation uses Modbus or IEC 61850. Instead, this document provides a framework specifying how a gateway maps any given data item from Modbus into an IEC 61850 substation, including the control direction.
Similarly, this document does not mandate which mapping framework a given gateway will be supporting. When this document is republished as a Technical Specification, conformance requirements will be identified.
This document recognizes that there will be situations in which a user will require that a gateway perform non-standard protocol mappings. Non-standard mappings are outside the scope of this document.
This document also recognizes that gateways typically manipulate the data passing through them in a variety of ways. Some of these functions include alarm trigger grouping, data suppression, interlocking and command blocking. Conformance to this document does not preclude a gateway from performing such functions, even though this document primarily specifies "straight through" mapping of Modbus data to IEC 61850-7-3:2010 and IEC 61850-7-3:2010/AMD1:2020 data. Subclause 7.5 of this document describes how some of these functions can be specified to a gateway by a mapping tool using XML representations of conversion functions.
The mapping architecture for the exchange of the run-time information consists of four parts:
a) Conceptual architecture of a gateway and associated use case
b) Mapping of the information model (Assign semantic to the Modbus data)
c) Mapping of the data (which is in fact part of the information model)
d) Mapping of the services (out of scope for this document)
This second edition cancels and replaces the first edition published in 2024. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) deficiencies / missing text in Edition 1 corrected.

Management of distributed energy storage systems based on electrically chargeable vehicle batteries - Part 1: Use cases and architectures (IEC 63382-1:2025)

EN IEC 63382-1:2026

The IEC 63382 series specifies the management of distributed energy storage systems, composed of electrically chargeable vehicle batteries (ECV-DESS), which are handled by an aggregator/flexibility operator (FO) to provide energy flexibility services to grid operators.
Aggregator and flexibility operator have the same meaning in the context of this document and represent the entity which aggregates a number of other network users (e.g. energy consumers, prosumers, DERs) bundling energy consumption or generation assets into manageable sizes for the energy system.
The aggregator/FO communicates with the charging station (CS) backend system, which is typically the system platform (HW, SW and HMI) of either a charging station operator (CSO), or a charging service provider (CSP).
The purpose of the data exchange is to perform flexibility services, and it takes place between the aggregator/FO and a dedicated interface located in the CS backend system, which has been defined FCSBE, flexibility port at the charging station backend.
This part of IEC 63382 describes the technical characteristics and architectures of ECV-DESS, including:
– EV charging stations configurations, comprising several AC-EVSEs and/or DC-EVSEs;
– individual EVs connected to grid via an EVSE and managed by an aggregator/FO.
The focus of this document is on the interface between the FO and the FCSBE and the data exchange at this interface, necessary to perform energy flexibility services (FS).
The FO/aggregator converts grid services and/or grid support functions requested by the grid operators (DSOs or TSOs) into multiple flexibility services to be provided by a number of CSs, utilizing their own optimization and resource allocation algorithms.
Communication between FO and grid operators (DSO, TSO), optimization algorithms adopted by FO, flexibility service bidding procedures are out of scope of this document.
The data exchange between FO and FCSBE typically includes:
– flexibility service request and response;
– flexibility services parameters;
– EV charging station configuration and technical capabilities;
– credentials check of parties involved in the flexibility service;
– FS execution related notifications;
– event log, detailed service record, proof of work.
The exchange of credentials has the purpose to identify, authenticate and authorize the actors involved in the flexibility service transaction, to check the validity of a FS contract and to verify the technical capabilities of the system EV + CS, and conformity to applicable technical standards to provide the requested flexibility service.
This document also describes the technical requirements of ECV-DESS, the use cases, the information exchange between the EV charging station operator (CSO) and the aggregator/FO, including both technical and business data.
It covers many aspects associated to the operation of ECV-DESS, including:
– privacy issues consequent to GDPR application (general data protection regulation);
– cybersecurity issues;
– grid code requirements, as set in national guidelines, to include ancillary services, mandatory functions and remunerated services;
– grid functions associated to V2G operation, including new services, as fast frequency response;
– authentication/authorization/transactions relative to charging sessions, including roaming, pricing and metering information;
– management of energy transfers and reporting, including information interchange, related to power/energy exchange, contractual data, metering data;
– demand response, as smart charging (V1G).
It makes a distinction between mandatory grid functions and market driven services, taking into account the functions which are embedded in the FW control of DER smart inverters.
This document deals with use cases, requirements and architectures of the ECV-DESSs with the associated EV charging stations.
Some classes of energy flexibility services (FS) have been identified and illustrated in dedic

Power systems management and associated information exchange - Data and communications security - Part 7: Network and System Management (NSM) data object models

SIST EN IEC 62351-7:2026

IEC 62351-7:2025 defines network and system management (NSM) data object models that are specific to power system operations. These NSM data objects will be used to monitor the health of networks and systems, to detect possible security intrusions, and to manage the performance and reliability of the information infrastructure. The goal is to define a set of abstract objects that will allow the remote monitoring of the health and condition of IEDs (Intelligent Electronic Devices), RTUs (Remote Terminal Units), DERs (Distributed Energy Resources) systems and other systems that are important to power system operations. Power systems operations are increasingly reliant on information infrastructures, including communication networks, IEDs, and self-defining communication protocols. Therefore, management of the information infrastructure has become crucial to providing the necessary high levels of security and reliability in power system operations. The telecommunication infrastructure that is in use for the transport of telecontrol and automation protocols is already subject to health and condition monitoring control, using the concepts developed in the IETF Simple Network Management Protocol (SNMP) standards for network management. However, power system specific devices (like teleprotection, telecontrol, substation automation, synchrophasors, inverters and protections) need instead a specific solution for monitoring their health. The NSM objects provide monitoring data for IEC protocols used for power systems (IEC 61850, IEC 60870-5-104) and device specific environmental and security status. As a derivative of IEC 60870-5-104, IEEE 1815 DNP3 is also included in the list of monitored protocols. The NSM data objects use the naming conventions developed for IEC 61850, expanded to address NSM issues. For the sake of generality these data objects, and the data types of which they are comprised, are defined as abstract models of data objects. In addition to the abstract model, in order to allow the integration of the monitoring of power system devices within the NSM environment in this part of IEC 62351, a mapping of objects to the SNMP protocol of Management Information Base (MIBs) is provided. The objects that are already covered by existing MIBs are not defined here but are expected to be compliant with existing MIB standards. For example protocols including EST, SCEP, RADIUS, LDAP, GDOI are not in scope. This edition of IEC 62351-7 cancels and replaces IEC 62351-7 published in 2017. This new edition constitutes a technical revision and includes the following significant technical changes with respect to IEC 62351-7: a) Reviewed and enriched the NSM object data model; b) UML model adopted for NSM objects description; c) SNMP protocol MIBs translation included as Code Components

This document also describes the technical requirements of ECV-DESS, the use cases, the information exchange between the EV charging station operator (CSO) and the aggregator/FO, including both technical and business data. It covers many aspects associated to the operation of ECV-DESS, including: – privacy issues consequent to GDPR application (general data protection regulation); – cybersecurity issues; – grid code requirements, as set in national guidelines, to include ancillary services, mandatory functions and remunerated services; – grid functions associated to V2G operation, including new services, as fast frequency response; – authentication/authorization/transactions relative to charging sessions, including roaming, pricing and metering information; – management of energy transfers and reporting, including information interchange, related to power/energy exchange, contractual data, metering data; – demand response, as smart charging (V1G). It makes a distinction between mandatory grid functions and market driven services, taking into account the functions which are embedded in the FW control of DER smart inverters. This document deals with use cases, requirements and architectures of the ECV-DESSs with the associated EV charging stations. Some classes of energy flexibility services (FS) have been identified and illustrated in dedicated use cases: – following a dynamic setpoint from FO; – automatic execution of a droop curve provided by FO, according to local measurements of frequency, voltage and power; – demand response tasks, stimulated by price signals from FO; – fast frequency response. Furthermore, some other more specific flexibility service use cases include: – V2G for tertiary control with reserve market; – V2H with dynamic pricing linked to the wholesale market price; – distribution grid congestion by EV charging and discharging. FS are performed under flexibility service contracts (FSC) which can be stipulated

Power systems management and associated information exchange - Data and communications security - Part 7: Network and System Management (NSM) data object models

IEC 62351-7:2025(Main)

IEC 62351-7:2025 defines network and system management (NSM) data object models that are specific to power system operations. These NSM data objects will be used to monitor the health of networks and systems, to detect possible security intrusions, and to manage the performance and reliability of the information infrastructure. The goal is to define a set of abstract objects that will allow the remote monitoring of the health and condition of IEDs (Intelligent Electronic Devices), RTUs (Remote Terminal Units), DERs (Distributed Energy Resources) systems and other systems that are important to power system operations.
Power systems operations are increasingly reliant on information infrastructures, including communication networks, IEDs, and self-defining communication protocols. Therefore, management of the information infrastructure has become crucial to providing the necessary high levels of security and reliability in power system operations.
The telecommunication infrastructure that is in use for the transport of telecontrol and automation protocols is already subject to health and condition monitoring control, using the concepts developed in the IETF Simple Network Management Protocol (SNMP) standards for network management. However, power system specific devices (like teleprotection, telecontrol, substation automation, synchrophasors, inverters and protections) need instead a specific solution for monitoring their health.
The NSM objects provide monitoring data for IEC protocols used for power systems (IEC 61850, IEC 60870-5-104) and device specific environmental and security status. As a derivative of IEC 60870-5-104, IEEE 1815 DNP3 is also included in the list of monitored protocols. The NSM data objects use the naming conventions developed for IEC 61850, expanded to address NSM issues. For the sake of generality these data objects, and the data types of which they are comprised, are defined as abstract models of data objects.
In addition to the abstract model, in order to allow the integration of the monitoring of power system devices within the NSM environment in this part of IEC 62351, a mapping of objects to the SNMP protocol of Management Information Base (MIBs) is provided.
The objects that are already covered by existing MIBs are not defined here but are expected to be compliant with existing MIB standards. For example protocols including EST, SCEP, RADIUS, LDAP, GDOI are not in scope.
This edition of IEC 62351-7 cancels and replaces IEC 62351-7 published in 2017. This new edition constitutes a technical revision and includes the following significant technical changes with respect to IEC 62351-7:
a) Reviewed and enriched the NSM object data model;
b) UML model adopted for NSM objects description;
c) SNMP protocol MIBs translation included as Code Components

Management of distributed energy storage systems based on electrically chargeable vehicle batteries - Part 1: Use cases and architectures

IEC 63382-1:2025(Main)

IEC 63382-1:2025 series specifies the management of distributed energy storage systems, composed of electrically chargeable vehicle batteries (ECV-DESS), which are handled by an aggregator/flexibility operator (FO) to provide energy flexibility services to grid operators.
IEC 63382-1:2025 describes the technical characteristics and architectures of ECV-DESS, including:
– EV charging stations configurations, comprising several AC-EVSEs and/or DC-EVSEs;
– individual EVs connected to grid via an EVSE and managed by an aggregator/FO.
The focus of this document is on the interface between the FO and the FCSBE and the data exchange at this interface, necessary to perform energy flexibility services (FS).
The data exchange between FO and FCSBE typically includes:
– flexibility service request and response;
– flexibility services parameters;
– EV charging station configuration and technical capabilities;
– credentials check of parties involved in the flexibility service;
– FS execution related notifications;
– event log, detailed service record, proof of work.
The exchange of credentials has the purpose to identify, authenticate and authorize the actors involved in the flexibility service transaction, to check the validity of a FS contract and to verify the technical capabilities of the system EV + CS, and conformity to applicable technical standards to provide the requested flexibility service.
This document also describes the technical requirements of ECV-DESS, the use cases, the information exchange between the EV charging station operator (CSO) and the aggregator/FO, including both technical and business data.
It covers many aspects associated to the operation of ECV-DESS, including:
– privacy issues consequent to GDPR application (general data protection regulation);
– cybersecurity issues;
– grid code requirements, as set in national guidelines, to include ancillary services, mandatory functions and remunerated services;
– grid functions associated to V2G operation, including new services, as fast frequency response;
– authentication/authorization/transactions relative to charging sessions, including roaming, pricing and metering information;
– management of energy transfers and reporting, including information interchange, related to power/energy exchange, contractual data, metering data;
– demand response, as smart charging (V1G).
It makes a distinction between mandatory grid functions and market driven services, taking into account the functions which are embedded in the FW control of DER smart inverters.
This document deals with use cases, requirements and architectures of the ECV-DESSs with the associated EV charging stations.
Some classes of energy flexibility services (FS) have been identified and illustrated in dedicated use cases:
– following a dynamic setpoint from FO;
– automatic execution of a droop curve provided by FO, according to local measurements of frequency, voltage and power;
– demand response tasks, stimulated by price signals from FO;
– fast frequency response.
Furthermore, some other more specific flexibility service use cases include:
– V2G for tertiary control with reserve market;
– V2H with dynamic pricing linked to the wholesale market price;
– distribution grid congestion by EV charging and discharging.
FS are performed under flexibility service contracts (FSC) which can be stipulated between:
– FO and EV owner (EVU or EV fleet manager);
– FO and CSP;
– FO and CSO.
Any flexibility service is requested by the aggregator/FO with a flexibility service request (FSR) communicated through the FCSBE interface to the available resources.
The actors EVU, CSO, CSP have always the right to choose opt-in or opt-out options in case of a FSR, unless it is mandatory for safety or grid stability reasons.
A use case shows how to discover flexibility service contract (FSC) holders.
This document describes many use cases, some of them are dedicated to special applications such as

IEC TR 61850-90-22:2024(Main)

Communication networks and systems for power utility automation – Part 90-22: SCD based substation network automated management with visualization and supervision support

IEC TR 61850-90-22:2024, which is a Technical Report, aims to provide analysis, principles, use cases and guidance on how to use GOOSE/SV static-routing or auto-routing based on System Configuration Description (SCD) file to automated manage the substation network while without changing the requirements of IEDs. Furthermore, this document also intends to give novel practices on network and GOOSE/SV path condition monitoring which support visualization and supervision from higher level application side.
Using the concepts developed in the IETF's Transparent Interconnection of Lots of Links (TRILL) using IS-IS protocol that is defined in RFC 6326 and ISO/IEC 10589 standards, this document defines network and system management data object models that are specific to power system operations. These data objects will be used to monitor the health of networks and systems, to detect abnormal behaviours of IEDs which contradict SCD file, such as unexpected IEDs or unexpected GOOSE/SV flows, and to support the management of the performance and reliability of the information infrastructure

IEC TR 61850-7-6:2024(Main)

Communication networks and systems for power utility automation - Part 7-6: Guideline for definition of Basic Application Profiles (BAPs) using IEC 61850

IEC TR 61850-7-6:2024, which is a Technical Report, is focused on building application / function profiles and specifies a methodology to define Basic Application Profiles (BAPs), in textual documents (edition 1, 2019) or in a machine processable SCL format (current edition). These Basic Application Profiles provide a framework for interoperable interaction within or between typical substation automation functions. BAPs are intended to define a subset of features of IEC 61850 in order to facilitate interoperability in a modular way in practical applications.
It is the intention of this document to provide a common and generic way to describe the functional behavior of a specific application function in the domain of power utility automation systems as a common denominator of various possible interpretations/implementations of using IEC 61850.
The guidelines in this document are based on the functional definitions of:
• IEC 61850-5, Communication requirements for functions and device models, which gives a comprehensive overview of all application functions needed in a state-of-the-art substation automation implementation.
• IEC TR 61850-7-500, Basic information and communication structure – Use of logical nodes for modelling application functions and related concepts and guidelines for substations, which illustrates and explains application functions for the substation/protection domain of Logical Nodes in modelling simple and complex functions, to improve common understanding in modelling and data exchange, and finally to lead to interoperable implementations.
• IEC TR 61850-90-3, Using IEC 61850 for condition monitoring diagnosis and analysis, which gives use cases and data modelling for condition monitoring diagnosis and analysis functions for substation and power grid facilities.
• IEC TR 61850-90-30, IEC 61850 Function Modelling in SCL, which describes extensions of the SCL Substation/Process Section allowing to create a comprehensive, IED and hardware independent specification of an IEC 61850 based power system.
This document does not describe the applications and respective implementation requirements; the focus is on their typical information exchange including data and communication services and engineering conventions.
This second edition cancels and replaces the first edition published in 2019. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) New Clause 5 added to describe the way to express Basic Application Profile in SCL files;
b) New Annex F and Annex G added to list specific use cases and roles of the Concept Definition Tool.

Communication networks and systems for power utility automation - Part 6: Configuration description language for communication in electrical substations related to IEDs

IEC 61850-6:2009(Main)

IEC 61850-6:2009 specifies a file format for describing communication-related IED (Intelligent Electronic Device) configurations and IED parameters, communication system configurations, switch yard (function) structures, and the relations between them. The main purpose of this format is to exchange IED capability descriptions, and SA system descriptions between IED engineering tools and the system engineering tool(s) of different manufacturers in a compatible way. The main changes with respect to the previous edition are as follows:
- functional extensions added based on changes in other Parts of IEC 61850, especially in IEC 61850-7-2 and IEC 61850-7-3;
- functional extensions concerning the engineering process, especially for configuration data exchange between system configuration tools, added;
- clarifications and corrections.
This publication is of core relevance for Smart Grid.
