Low-voltage electrical installations - Part 8-2: Prosumer's low-voltage electrical installations

This part of IEC 60364 provides additional requirements, measures and recommendations for
design, erection and verification of all types of low-voltage electrical installation according to
IEC 60364-1:2005, Clause 11, including local production and/or storage of energy in order to
ensure compatibility with the existing and future ways to deliver electrical energy to currentusing
equipment or to the public network by means of local sources. Such electrical
installations are designated as prosumer’s electrical installations (PEIs).
This document also provides requirements for proper behaviour and actions of PEIs in order
to efficiently obtain sustainable and safe operations of these installations when integrated into
smart grids.
These requirements and recommendations apply, within the scope of IEC 60364 (all parts),
for new installations and modification of existing installations.
NOTE Electrical sources for safety services including associated electrical installations and standby electrical
supply systems for a secure continuity of supply, which are operated only occasionally and for short periods (e.g.
monthly one hour) in parallel with the distribution grid for testing purposes, are outside the scope of this document.

Le présent document spécifie également des exigences relatives au comportement et aux actions adaptés des PEI afin d'assurer leur fonctionnement durable et sûr lorsque ces PEI sont intégrées dans des réseaux intelligents. Ces exigences et recommandations s'appliquent, dans les limites du domaine d'application de l'IEC 60364 (toutes les parties), aux installations neuves et à la modification des installations existantes.

Nizkonapetostne električne inštalacije - 8-2. del: Električne inštalacije proizvajalcev-odjemalcev

Ta del standarda IEC 60364 določa dodatne zahteve, ukrepe in priporočila za načrtovanje, postavitev in preverjanje vseh vrst nizkonapetostnih električnih inštalacij v skladu s standardom IEC 60364-1:2005, točka 11, vključno z lokalno proizvodnjo in/ali shranjevanjem energije za zagotavljanje združljivosti z obstoječimi in prihodnjimi načini prenosa električne energije do električnega porabnika ali javnega omrežja prek lokalnih virov. Takšne električne inštalacije so zasnovane kot električne inštalacije aktivnih odjemalcev (PEI).
Ta dokument prav tako določa zahteve za ustrezno ravnanje in delovanje električnih inštalacij aktivnih odjemalcev za učinkovito zagotovitev trajnostnega in varnega delovanja teh inštalacij, kadar so integrirane v pametna omrežja.
Te zahteve in priporočila veljajo, v okviru skupine standarda IEC 60364 (vsi deli), za nove inštalacije in spremembe obstoječih inštalacij.
OPOMBA: Viri električne energije za varnostno napajanje, vključno s povezanimi električnimi inštalacijami in pomožnimi napajalnimi sistemi za varno neprekinjeno napajanje, ki delujejo samo občasno in krajše obdobje (npr. eno uro mesečno) vzporedno z distribucijskim omrežjem za preskusne namene, so zunaj področja uporabe tega dokumenta.

LOW-VOLTAGE ELECTRICAL INSTALLATIONS –
Part 8-2: Prosumer’s low-voltage electrical installations
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.

International Standard IEC 60364-8-2 has been prepared by IEC technical committee 64:

Electrical installations and protection against electric shock.
The text of this International Standard is based on the following documents:

INTRODUCTION

Historically, utilities were managing the public transmission and distribution network from the

point of view of having a central production adapted to demand variation, a top-down energy

flow, a production/consumption balance done by integrated utility companies and with rather

passive users.
The following key factors are pushing the public electricity network to change:

• the increasing number of electronic devices used daily and the growing needs as well as

future needs (e.g. charging electric vehicles) will result in the structural growing of

electricity consumption;

• the mediated pressure on climate change results in pressure on CO emissions reduction;

• the electricity market is also quickly changing due mainly to its unbundling and

deregulation, and to the greater number of intermittent renewable energy sources (global

and local);

• users’ expectations are also evolving as a result of an increasing need for better public

networks reliability and quality, the search for better economic performance and the

willingness to pro-actively manage their energy;

• technological evolution should also be considered as information and communication

technology (ICT) is affordable and new energy storage solutions are emerging.

All stakeholders directly involved in the electricity generation, transmission, distribution and

consumption have new expectations:

• customers are willing to reduce electrical energy costs in order to meet environment

targets (renewable energy, energy efficiency) but also wish to benefit from the quality of

electricity supply;
• suppliers wish to limit customer churn rate with price and service management;

• producers expect to maximize their yield of assets, to optimize their investments and to

take profit from energy trading;
• the aggregator wants to create conditions suitable for new market emergence;

• the transmission system operator (TSO) aspires to a robust transmission public network

and to meet regulation objectives (price and level of services), while the distribution

system operator (DSO) wants to meet regulation objectives (price and level of services), to

reduce costs by productivity (including meter) and to have a flexible network;

• finally, governments and regulators are willing to create a competitive and sustainable

energy market.

The objective of this document is to ensure that the low-voltage electrical installation is

compatible with the current and future ways to deliver safely and functionally the electrical

energy to current-using equipment either from the public network or from other local sources.

This document is not intended to influence all stakeholders of electricity supply on how the

electrical energy should be sold and delivered.

LOW-VOLTAGE ELECTRICAL INSTALLATIONS –
Part 8-2: Prosumer’s low-voltage electrical installations
1 Scope

This part of IEC 60364 provides additional requirements, measures and recommendations for

design, erection and verification of all types of low-voltage electrical installation according to

IEC 60364-1:2005, Clause 11, including local production and/or storage of energy in order to

ensure compatibility with the existing and future ways to deliver electrical energy to current-

using equipment or to the public network by means of local sources. Such electrical

installations are designated as prosumer’s electrical installations (PEIs).

This document also provides requirements for proper behaviour and actions of PEIs in order

to efficiently obtain sustainable and safe operations of these installations when integrated into

smart grids.

These requirements and recommendations apply, within the scope of IEC 60364 (all parts),

for new installations and modification of existing installations.

NOTE Electrical sources for safety services including associated electrical installations and standby electrical

supply systems for a secure continuity of supply, which are operated only occasionally and for short periods (e.g.

monthly one hour) in parallel with the distribution grid for testing purposes, are outside the scope of this document.
