Smart grid user interface - Part 2: Architecture and requirements
IEC TS 62939-2:2018(E), which is a Technical Specification, provides an architecture to define interfaces for the information exchange between smart equipment/systems from the demand side and the power grid. It facilitates the interoperability between the IEC common information model (CIM) and customer facility standards for smart grid applications.
This document presents one possible architecture to connect non-CIM/IEC 61850-based demand-side standards to the CIM, to support demand response type applications.
It presents an immediately available architecture approach for home and building grid users for demand response applications to cope with the fragmented market and lack of harmonized standard solutions. It proposes that a three-layer application be implemented but this does not preclude the ongoing long-term efforts of IEC ideally to promote from a semantic perspective only two-layer implementations.

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. In exceptional
circumstances, a technical committee may propose the publication of a technical specification
when
• the required support cannot be obtained for the publication of an International Standard,
despite repeated efforts, or
• the subject is still under technical development or where, for any other reason, there is the
future but no immediate possibility of an agreement on an International Standard.
Technical specifications are subject to review within three years of publication to decide whether
they can be transformed into International Standards.
IEC TS 62939-2, which is a Technical Specification, has been prepared by IEC project
committee 118: Smart grid user interface.

INTRODUCTION
Over the years, several ecosystems (especially telecommunications, sustainable energy, home
automation) have been growing in parallel but separately in the customer premises. The
perspective of energy applications is triggering a high level of interest in new markets such as
smart home, smart community, smart building, smart industrial park, distributed energy
resources, and electric vehicles. It is a growing trend that the traditional energy consumer may
eventually turn out to be the prosumer, who not only consumes power from but also feeds power
back to the grid, which raises the challenge for grid management.
Considering the relevance and common interests while connecting various demand-side objects
with the power grid, it is urgent and important to ensure effective, economical and secure
operation of the power grid from the point of view of a user as well as enhance the energy
efficiency of the demand-side system and equipment. Under the circumstances, information
exchange may play a more critical role in this field. Currently, various communication standards
have been developed by organizations and manufacturers for customer facility management
and control. However, the industry has become impatient with the lack of standard interfacing
methods and solutions to exchange information with the grid.
This document focuses on standardization in the field of interfacing for information exchange
between smart equipment and/or systems and the grid from the point of view of the user to the
grid for customer facility management and control applications.
IEC 62939 consists of the following parts under the general title Smart grid user interface:
Part 1: Interface overview and country perspectives
Part 2: An architecture and requirements
In addition to the above parts, two documents in the IEC 62746 series cover the SGUI bridge
standard for demand response application. The first is IEC PAS 62746-10-1 and the other is
IEC 62746-10-3.

SMART GRID USER INTERFACE –
Part 2: An architecture and requirements
1 Scope
This part of IEC 62939 provides an architecture to define interfaces for the information
exchange between smart equipment/systems from the demand side and the power grid. It
facilitates the interoperability between the IEC common information model (CIM) and customer
facility standards for smart grid applications.
This document presents one possible architecture to connect non-CIM/IEC 61850-based
demand-side standards to the CIM, to support demand response type applications. It presents
an immediately available architecture approach for home and building grid users for demand
response applications to cope with the fragmented market and lack of harmonized standard
solutions.
It proposes that a three-layer application be implemented but this does not preclude the ongoing
long-term efforts of IEC ideally to promote from a semantic perspective only two-layer
implementations.
