The requirements, recommendations, and guidance of this part of IEC 60364 apply to low-voltage electrical installation 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 local connected sources delivering it to:
– current-using equipment, and/or
– local storage units, and/or
– distribution network.
Such electrical installations are designated as Prosumer’s Electrical Installations (PEI).
These requirements and recommendations apply for new installations and modification of existing installations.
This document also provides requirements and recommendations for proper behaviour and actions of PEI in order to efficiently obtain sustainable and safe operations of these installations when integrated into smart grids.
NOTE: requirements for Electrical sources for safety services are given 60364-5-56
Information related to grid interaction to ensure the stability of the electrical system for grid connected PEI are covered in annex B
This document covers the requirements related to stability of the PEI when island or stand alone.
