Grid integration of renewable energy generation - Terms and definitions
IEC 62934:2021 provides terms and definitions in the subject area of grid integration of renewable energy generation. The technical issues of grid integration mainly focus on the issues caused by renewable energy generation with variable sources and/or converter based technology, such as wind power and photovoltaic power generation. Some renewable energy generations such as hydro power and biomass power with a relatively continuously available primary energy source and a rotating generator are conventional sources of generation, and are therefore not covered in this document. The intention of this document is to answer the question "what do the words mean" and not "under what conditions do the terms apply".

Intégration de la production d’énergie renouvelable aux réseaux électriques - Termes et définitions
IEC 62934:2021 fournit des termes et définitions relatifs au domaine de l’intégration de la production d’énergie renouvelable aux réseaux électriques. Les questions techniques de l’intégration aux réseaux électriques portent principalement sur les problèmes causés par la production d’énergie renouvelable (par exemple, l’énergie éolienne et l’énergie photovoltaïque) à partir de sources variables et/ou de technologies à base de convertisseurs. Certaines productions d’énergie renouvelable telles que l’énergie hydraulique et la biomasse obtenues à partir d’une source d’énergie primaire disponible de manière relativement continue et d’une génératrice tournante, constituent des sources de production conventionnelles et ne sont donc pas couvertes par le présent document. Le présent document est destiné à répondre à la question "que signifient les termes?" et non "dans quelles conditions les termes s’appliquent?"

GRID INTEGRATION OF RENEWABLE ENERGY GENERATION –
TERMS AND DEFINITIONS
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.
IEC 62934 has been prepared by subcommittee 8A: Grid Integration of Renewable Energy
Generation, of IEC technical committee 8: System aspects of electrical energy supply. It is an
International Standard.
The text of this International Standard is based on the following documents:

INTRODUCTION
The purpose of this terminology document is to provide terms and definitions for all publications
under the responsibility of SC 8A. In this document, renewable energy generation is the electric
power generation which uses renewable energy as its primary source for the conversion into
electricity.
All SC 8A normative documents to be published should keep consistency with this International
Standard (IS). This IS will be revised together with other SC 8A publications in order to avoid
mismatches when necessary.
From the technical point of view, grid integration of renewable energy generation is a
interdisciplinary complex technical field which is concerned with basic equipment, system
integration, control and protection, operation and dispatch, market and trade and so on. Without
a strong standardization of terminology, focal terms can have a different understanding by
different countries, parties, and technical areas. Harmonised vocabulary is critical also from the
market point of view. It impacts economics and this can become a barrier to commerce. The
correct comparison among different options is fundamental, therefore basic terms and
definitions impact economic decisions.
Several IEC product standards give definitions of certain terms which are necessary for the
understanding of how to design, manufacture and use of those products. The International
Electrotechnical Vocabulary (IEV, IEC 60050, http://www.electropedia.org) and the IEC
Glossary (http://std.iec.ch/glossary) allow on-line access to this information.
Terms and definitions of this document have been harmonized with the IEV, the IEC Glossary
and other IEC documents as far as possible. Definitions not included in this terminology
standard may be found elsewhere in other IEC documents.
The use of abbreviations has been optimized, on the one hand to avoid tedious repetition and,
on the other hand, to avoid confusion. A minimum set of abbreviations is identified in Clause
...
