The IEC SRD 62913 delivers an applicable methodology to draft Use Cases (Part 1), clarifying ‘who does what’ with regards to Smart Energy Use Cases, and it also initiates the process of listing, organising and making available the Use Cases which carry the Smart Energy requirements which should be addressed by the IEC core technical standards (Part 2).


Part 1

Specific application of the Use Case methodology for defining generic smart grid requirements according to the IEC systems approach

This part of the IEC 62913 describes a common approach to define Generic Smart Grid Requirements. It uses as input the Use Case Methodology defined as part of IEC 62559 series, namely the Use Case template, and provides a method and tools for describing Generic Use Cases. This is necessary to help ensure a consistent and homogeneous description of requirements for the different areas which make up the Smart Grid environment.

It also provides a consolidated overview of the roles and of the Generic Use Cases that are described in Part 2 of IEC 62913 series. As such, this section of the present document (under clause 7 ‘Consolidated Smart Grid Role Model’) will be updated as new editions of Part 2 are published.

Part 2

is composed of five subparts which refer to the clusters that group several domains:

  • Part 2-1: Grid related domains – these include transmission grid management,
  • Part 2-2: Market related domain;
  • Part 2-3: Resources connected to the grid related domains – these include bulk generation, distributed energy resources, smart home / commercial / industrial / DRcustomer energy management, and energy storage;
  • Part 2-4: Electric transportation related domain;
  • Part 2-5: Support functions related domains – these include metering management and asset management.

Part 2-1: Grid related domains – these include transmission grid management, Distribution Grid Management, Microgrids and Smart Substation Automation

This part of IEC SRD 62913 initiates and illustrates the IEC’s systems approach based on Use Cases and involving the identification of generic smart grid requirements for further standardization work for grid related domains – i.e. grid management regrouping:

transmission grid management, distribution grid management, microgrids and smart substation automation domains – based on the methods and tools developed in IEC SRD 62913-1.

The Grid management domain groups Use Cases and associated requirements common to the EHV, HV and MV/LV networks operations and the business analysis of the general electric network life cycle. Use Cases specific to parts of the general electric network are described in transmission grid management, distribution grid management, microgrids and smart substation automation clauses.

This document captures possible “common and repeated usage” of a smart grid system, under the format of “Uses Cases” with a view to feeding further standardization activities. Use Cases can be described in different ways and can represent competing alternatives. From there, this document derives the common requirements to be considered by these further standardization activities in term of interfaces between actors interacting with the given system.
