Description

BS PD IEC/TS 62786 – Distributed energy resources connection with the grid

BS PD IEC/TS 62786:2017 provides principles and technical requirements for distributedenergy resources (DERs) connected to the distribution network. It applies to the planning,design, operation and connection of DERs to distribution networks. It includes generalrequirements, connection scheme, choice of switchgear, normal operating range, immunity todisturbances, active power response to frequency deviation, reactive power response tovoltage variations and voltage changes, EMC and power quality, interface protection,connection and start to generate electrical power, active power management, monitoring,control and communication, and conformance tests.

This document specifies interface requirements for connection of generating plants with thedistribution network operating at a nominal frequency of 50 Hz or 60 Hz.

DERs include distributed generation and permanently connected electrical energy storage inthe form of synchronous generators, asynchronous generators, converters, etc., connected tothe medium voltage (MV) or low voltage (LV) distribution network.

NOTE Mobile electrical energy storage devices (e.g. electrical vehicles) are under consideration for futureeditions.

The requirements of this document can be superseded by laws and regulations whereapplicable.
