IEC SRD 63268:2020(E) depicts a comprehensive standardization landscape of the interfaces between the main grid stakeholders and the grid users, grid users comprising DERs and Customer Premises.
This document considers the main "physical" and "logical" interactions (i.e. through wires/functions – power and/or communication) between grid users and grid stakeholders, both from an electrical standpoint and from a data standpoint. Then for each interaction type, the document presents the standardiz...

The scope of this part of IEC 61968 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 looselycoupled
implementations, there are no technical limitations for systems with which a DERMS
might exchange information. Also, it ...

The common information model (CIM) 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 and interoperability of network applications
developed independently by different vendors, between entire systems running network
applications developed ind...

The scope of this part of IEC 62351 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 inc...

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.
