IEC 62386-221:2018

Digital addressable lighting interface - Part 221: Particular requirements for control gear - Demand response (device type 20)

IEC 62386-221:2018 specifies the methodology of demand response which focuses on the curtailment of electric loads during peak demand times thus avoiding the requirement to find new sources of generation capacity. By using load shedding, the lighting system responds to the demands of the energy supply.
This document is applicable to control gear supporting the demand response functionality.

Interface d’éclairage adressable numérique - Partie 221: Exigences particulières pour les appareillages de commande - Réaction à la demande (dispositifs de type 20)

L’IEC 62386-221:2018 spécifie la méthodologie de la réaction à la demande qui cible la réduction de la consommation des charges électriques au cours des périodes de pointe de la demande, ce qui évite l’exigence de nouvelles sources de capacité de production. À l’aide du délestage, le système d’éclairage répond aux demandes de l’alimentation en énergie.
Le présent document s’applique aux appareillages de commande prenant en charge la fonctionnalité de réaction à la demande.

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
