IEC 61970-301:2020(Main)
Energy management system application program interface (EMS-API) - Part 301: Common information model (CIM) base

IEC 61970-301:2020 lays down the common information model (CIM), which is an abstract model that represents all the major objects in an electric utility enterprise typically involved in utility operations. By providing a standard way of representing power system resources as object classes and attributes, along with their relationships, the CIM facilitates the integration of network applications developed independently by different vendors, between entire systems running network applications developed independently, or between a system running network applications and other systems concerned with different aspects of power system operations, such as generation or distribution management. SCADA is modeled to the extent necessary to support power system simulation and inter-control centre communication. The CIM facilitates integration by defining a common language (i.e. semantics) based on the CIM to enable these applications or systems to access public data and exchange information independent of how such information is represented internally.
This edition reflects the model content version ‘IEC61970CIM17v38’, dated ‘2020-01-21’, and includes the following significant technical changes with respect to the previous edition:
a) Added Feeder modelling;
b) Added ICCP configuration modelling;
c) Correction of issues found in interoperability testing or use of the standard;
d) Improved documentation;
e) Updated Annex A with custom extensions;
f) Added Annex B Examples of PST transformer modelling;
g) Added Annex C HVDC use cases.

IEC 61968-5:2020(Main)
Application integration at electric utilities - System interfaces for distribution management - Part 5: Distributed energy optimization

IEC 61968-5:2020 is the description of a set of functions that are needed for enterprise integration of DERMS functions. These exchanges are most likely between a DERMS and a DMS. However, since this is an enterprise integration standard which may leverage IEC 61968-100:2013 for application integration (using web services or JMS) or other loosely-coupled implementations, there are no technical limitations for systems with which a DERMS might exchange information. Also, it should be noted that a DERMS might communicate with individual DER using a variety of standards and protocols such as IEC 61850, IEEE 2030.5, Distribution Network Protocol (DNP), Sunspec Modbus, or perhaps Open Field Message Bus (OpenFMB). One role of the DERMS is to manage this disparity and complexity of communications on the behalf of the system operator. However, the communication to individual DER is out of scope of this standard. Readers should look to those standards to understand communication to individual DER’s smart inverter.
The scope will be limited to the following use case categories:
• DER group creation – a mechanism to manage DER in aggregate
• DER group maintenance – a mechanism to add, remove, or modify the members and/or aggregated capabilities of a given group of DER
• DER group deletion – removing an entire group
• DER group status monitoring – a mechanism for quantifying or ascertaining the current capabilities and/or status of a group of DER
• DER group forecast – a mechanism for predicting the capabilities and/or status of a group of DER for a given time period in the future
• DER group dispatch – a mechanism for requesting that specified capabilities of a group of DER be dispatched to the grid
• DER group voltage ramp rate control – a mechanism for requesting that a DER group following a ramp rate curve
• DER group connect/disconnect – a mechanism to request that DER either isolate themselves, or reconnect to the grid as needed.

IEC TS 61850-1-2:2020(Main)
Communication networks and systems for power utility automation - Part 1-2: Guideline on extending IEC 61850

IEC TS 61850-1-2:2020, which is a technical specification, is intended for any users but primarily for standardization bodies that are considering using IEC 61850 as a base standard within the scope of their work and are willing to extend it as allowed by the IEC 61850 standards. This document identifies the required steps and high-level requirements in achieving such extensions of IEC 61850 and provides guidelines for the individual steps.
Within that scope, this document addresses the following cases:
• The management of product-level standards for products that have an interface based on IEC 61850
• The management of domain-level standards based on IEC 61850
• The management of transitional standards based on IEC 61850
• The management of private namespaces based on IEC 61850
• The development of standards offering the mapping of IEC 61850 data model at CDC level
• The development and management of IEC 61850 profiles for domains (underlying the role of IEC TR 62361-103 and IEC TR 61850-7-6)
This document includes both technical and process aspects:
On the technical side, this document:
• Reminds the main basic requirements (mostly referring to the appropriate parts of the series which host the requirements or recommendations)
• Lists all possible flexibilities offered by the standards
• Defines which flexibilities are allowed/possible per type of extension cases
On the process side, the document covers:
• The initial analysis of how the existing IEC 61850 object models and/or communication services may be applied and what allowed extensions may be required for utilizing them in new or specific domains (including private ones). The results of that step are expected to be documented
• The extension of the IEC 61850 object models for new domains. The typical associated work is to identify existing logical nodes which can be reused "as is", to determine if existing logical nodes can be extended, or to define new logical nodes
• The purpose and process to use transitional namespaces, which are expected to be merged eventually into an existing standard namespace
• The management of standard namespaces
• The development of private namespaces

IEC 61968-1:2020(Main)
Application integration at electric utilities - System interfaces for distribution management - Part 1: Interface architecture and general recommendations

IEC 61968-1:2020 is the first in a series that, taken as a whole, defines interfaces for the major elements of an interface architecture for power system management and associated information exchange.
This document identifies and establishes recommendations for standard interfaces based on an Interface Reference Model (IRM). Subsequent clauses of this document are based on each interface identified in the IRM. This set of standards is limited to the definition of interfaces. They provide for interoperability among different computer systems, platforms, and languages. IEC 61968-100 gives recommendations for methods and technologies to be used to implement functionality conforming to these interfaces.
As used in IEC 61968, distribution management consists of various distributed application components for the utility to manage electrical distribution networks. These capabilities include monitoring and control of equipment for power delivery, management processes to ensure system reliability, voltage management, demand-side management, outage management, work management, network model management, facilities management, and metering. The IRM is specified in Clause 3. The IRM defines the high-level view of the TC 57 reference architecture and the detailed in the relevant 61968 series, 61970 series or 62325 series. The goal of the IRM is to provide a common relevant context view for TC 57 that covers domains like transmission, distribution, market, generation, consumer, regional reliability operators, and regulators.
This third edition cancels and replaces the second edition published in 2012. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) update of IRM section, which has been out of date since the 2nd edition;
b) update to IRM model using ArchiMate modelling language;
c) addition of missing business functions and business objects;
d) alignment with newly released documents from the technical committee;
e) alignment with IEC 61968-100;
f) update of annexes.
