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...view more

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 ...view more

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...view more

IEC 62715-6-3:2020 (E) is to define the standard test methods to evaluate the mechanical robustness of flexible display modules, especially mechanical robustness regarding impact and hardness, which include displays such as liquid crystal displays (LCDs), e-paper, and organic light emitting diode (OLED) displays, against external forces applied to a panel.

IEC TS 62898-3-1:2020(E) provides guidelines for the specification of fault protection and dynamic control in microgrids. Protection and dynamic control in a microgrid are intended to ensure safe and stable operation of the microgrid under fault and disturbance conditions.
This document applies to AC microgrids comprising single or three-phase networks or both. It includes both isolated microgrids and non-isolated microgrids with a single point of connection (POC) to the upstream distribution n...view more

IEC 60120:2020 define the dimensions of a series of standard ball and socket couplings using the standard locking devices (see IEC 60372) in order to permit the assembly of insulators or metal fittings supplied by different manufacturers. This document applies to string insulator units of the cap and pin and long rod types and their associated metal fittings. For the pin ball and the socket, dimensions apply to the finished product after any surface treatment. Extreme positions of the pin ball i...view more

IEC 60372:2020 is applicable to locking devices used with ball and socket couplings of string insulator units and used with the corresponding metal fittings standardized in IEC 60120, when they are supplied separately.The object of this document is
- to define the shapes and some standard dimensions for locking devices,
- to define the test methods for locking devices,
- to state the acceptance conditions for supply,
- to give other dimensions for guidance of manufacturing only.

IEC SRD 63199:2020 presents the current status of the IEC systems committee Smart Energy (SyC SE) development plan for readers (not limited to IEC smart energy related members). The document identifies items that require standardization, their current status and work required, possibly by multiple technical committees or working groups, to address any issues.
Since the content of this document represents a snapshot of the dynamic/living standardization processes to be updated, it is subject to ...view more

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...view more

This part of IEC 61968 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 pr...view more
