Full Description

This part of IEC 60364 provides requirements and recommendations that apply to low-voltage electrical installations connected or not to a distribution network able to operate:
– with local power supplies, and/or
– with local storage units,
and that monitors and controls the energy from the locally connected sources delivering it to:
– current-using equipment, and/or
– local storage units, and/or
– distribution networks.

Such electrical installations are designated as prosumer's electrical installations (PEIs).

These requirements and recommendations apply to new installations and modifications of existing installations.

This document also provides requirements and recommendations for the safe, efficient and correct behaviour of these installations when integrated into a smart grid.

NOTE Requirements for electrical sources for safety services are given in IEC 60364-5-56. Information related to grid interaction to ensure the stability of the electrical system for grid
connected PEIs is given in Annex B.

This document covers the requirements related to stability of islanded and stand-alone PEIs.
