Power systems management and associated information exchange - Part 2: Use Cases and role model

IEC 62357-2:2019 (E), which is a technical report, establishes the list of Use Cases developed by TC 57, Power systems management and associated information exchanges, in order to prepare International Standards, Technical Reports and Technical Specifications. Use Cases are fundamental to TC 57 publications This Technical Report:
• Identifies in existing standards, technical specification, reports and in ongoing TC 57 work (CD, DTS, DTR etc.) the Use Cases used as well as their links to standards, their status as Use Cases (level of description, standardization of the description referring to IEC 62559) and as IEC deliverables (are they in a TR/TS/IS, what is the status of the document CD, CDV etc.)
• Helps System Committees consolidate Use Cases through terminology and term definition work (link with existing relevant standards on the TC Terminology) and building links between roles and modelling frameworks (Role models). For example in TC 57 building links between the Use Case methodology and the roles used in IEC 62913-2 with CIM Interface Reference Model (IRM – IEC 61968).
• Shares and promotes those Use Cases within TC 57 and outside it. TC 57 mainly describes System Use Cases in the standards it publishes. Business roles and business Use Cases are mainly described within SyC SE (System Committee Smart Energy) deliverables (IEC 62559 series and IEC 62913 series).
• This document provides good input in reusing System Use Cases and System Roles inside and outside TC 57.
• Explains the content of its Use Cases to potential users and providing support on using those Use Cases for standardization (Normative context, maturity of the Use Case, location in standardization work, roles implied)
Those Use Cases aimed to be used as tools to identify requirements as input to further development of technical standards (whether TC 57 or not) and improve the consistency in this work and in that way contribute to interoperability. Use Cases facilitate cooperation at a system level with TCs, other standards-developing organizations, non-traditional players of electrotechnology, and regional organizations. Inside the IEC they provide a convergence platform with overall system level value for support of the Technical Committees and other standard development groups.
This document allows TC 57 to self-assess its work on Use Cases through KPIs (Key Performance Indicator) such as:
• % of Use Cases compliant with IEC 62559-2
• % of Business Use Cases (BUC) and System Use Cases (SUC)
• % of Business Roles and System Roles

Part 2: Use cases and role models
FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

international co-operation on all questions concerning standardization in the electrical and electronic fields. To

this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC

Publication(s)"). Their preparation is entrusted to technical committees; any IEC National Committee interested

in the subject dealt with may participate in this preparatory work. International, governmental and non-

governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely

with the International Organization for Standardization (ISO) in accordance with conditions determined by

agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence

between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in

the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of

patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

The main task of IEC technical committees is to prepare International Standards. However, a

technical committee may propose the publication of a Technical Report when it has collected

data of a different kind from that which is normally published as an International Standard, for

example "state of the art".

IEC 62357-2, which is a technical report, has been prepared by IEC technical committee 57:

Power systems management and associated information exchange.
The text of this Technical Report is based on the following documents:

INTRODUCTION
The IEC is in an operational implementation phase of the System approach of

standardization. Technical Committee 57 (TC 57) has a crucial role in helping other

Application Domain TCs extending their core standards (i.e. CIM

standards/IEC 61850/IEC 62746/IEC 62351) to their specific domains. This should ensure

efficient and secured power network management.

In the system approach working process, it is important for TC 57 to be able to consolidate,

share and explain the numerous Use Cases serving as basis for its standardization work.

These Use Cases are an excellent tool for design and implementation of new processes, also

for external organisations (SDOs, User Groups, Alliances etc.)

The mission of this Technical Report is to list the Use Cases featured in the TC 57

standardization work, thus making them available for re-use in on-going and future work.

Hopefully this will also promote Use Cases as a good tool for further work.

The intended audience for the document is the experts of TC 57 for their standardization work

or experts of other Application Domain TCs for on-going standardization work, independently

from TC 57 or through Joint Working Groups (JWG) or Task Forces (TF), as well as roadmaps

and strategic vision through Ad-hoc Groups, Strategic Groups, System Evaluation Groups or

System Committees.

This document structures and consolidates the TC 57 Use Cases (Status, WG and documents

linked, roles used, roadmap) to facilitate their use and re-use. It will list the following

elements:

• Existing Use Cases used to develop standards and their links with source documents, the

IEC Status of this source document, a short Use Case description, its compliance to

IEC 62559-2

• A roadmap: planned or drafted Use Cases (in on-going standardization work and PWI)

• Roles used in those Use Cases
• Terminology used in standardization work and not present in existing standards
This Technical report is split by active Working Group (WG) of TC 57
• WG 10 Power system IED communication and associated data models
• WG 13 Energy Management Systems Application Program Interfaces (EMS API)"
• WG 14 System interfaces for distribution management
• WG 15 Data and Communication Security
• WG 16 Deregulated Market Communications

• WG 17 Power system intelligent electronic device communication and associated data

models for distributed energy resources and distribution automation
• WG 18 Hydroelectric power plants – Communication for monitoring and control
• WG 19 Interoperability within TC 57 in the long term

• WG21 Interfaces and protocol profiles relevant to systems connected to the electrical grid

Part 2: Use cases and role models
1 Scope

This part of IEC 62357, which is a technical report, establishes the list of Use Cases

developed by TC 57, Power systems management and associated information exchanges, in

order to prepare International Standards, Technical Reports and Technical Specifications.

Use Cases are fundamental to TC 57 publications, as shown in Figure 1.
Figure 1 – TC 57 core standards
The Use Case creation process is shown in Figures 2, 3 and 4.

This Technical Report:

• Identifies in existing standards, technical specification, reports and in ongoing TC 57 work

(CD, DTS, DTR etc.) the Use Cases used as well as their links to standards, their status

as Use Cases (level of description, standardization of the description referring to

IEC 62559) and as IEC deliverables (are they in a TR/TS/IS, what is the status of the

document CD, CDV etc.)

• Helps System Committees consolidate Use Cases through terminology and term definition

work (link with existing relevant standards on the TC Terminology) and building links

between roles and modelling frameworks (Role models). For example in TC 57 building

links between the Use Case methodology and the roles used in IEC 62913-2 with CIM

Interface Reference Model (IRM – IEC 61968).
• Shares and promotes those Use Cases within TC 57 and outside it. TC 57 mainly

describes System Use Cases in the standards it publishes. Business roles and business

Use Cases are mainly described within SyC SE (System Committee Smart Energy)
deliverables (IEC 62559 series and IEC 62913 series).

• This document provides good input in reusing System Use Cases and System Roles inside

and outside TC 57.

• Explains the content of its Use Cases to potential users and providing support on using

those Use Cases for standardization (Normative context, maturity of the Use Case,

location in standardization work, roles implied)

Those Use Cases aimed to be used as tools to identify requirements as input to further

development of technical standards (whether TC 57 or not) and improve the consistency in

this work and in that way contribute to interoperability. Use Cases facilitate cooperation at a

system level with TCs, other standards-developing organizations, non-traditional players of

electrotechnology, and regional organizations. Inside the IEC they provide a convergence

platform with overall system level value for support of the Technical Committees and other

standard development groups.

This document allows TC 57 to self-assess its work on Use Cases through KPIs (Key

Performance Indicator) such as:
• % of Use Cases compliant with IEC 62559-2
• % of Business Use Cases (BUC) and System Use Cases (SUC)
• % of Business Roles and System Roles
• % of non-defined roles

Another objective of this document is to fill up the TC 57 Use Case Repository, as shown in

Figure 5.

numerous major uncertainties in its framework (regulatory, business or technological).

3.4
role

type of actor which has responsibilities and represents the external intended behavior of a

party

EXAMPLE 1 A legally defined market participant (e.g. grid operator, customer), a generic role which represents a

bundle of possible roles (e.g. flexibility operator) or an artificially defined body needed for generic process and Use

Case descriptions.

Note 1 to entry: IEC TS 62913 uses two kinds of roles: Business Roles and System Roles.

is, typically, of value for one or more actors or other stakeholders of the system

Note 1 to entry: There are two types of Use Cases:

– Business Use Cases describe how Business Roles interact to execute a business process. These processes

are derived from services, i.e. business transactions, which have previously been identified.

– System Use Cases describe how System and/or Business Roles of a given system interact to perform a Smart

Grid Function required to enable / facilitate the business processes described in Business Use Cases. Their

purpose is to detail the execution o
