UNE-EN IEC 61850-7-420:2021

This International Standard defines the IEC 61850 information models to be used in the exchange ofinformation with distributed energy resources (DER) and Distribution Automation (DA) systems. DERsinclude distribution-connected generation systems, energy storage systems, and controllable loads, aswell as facility DER management systems, including aggregated DER, such as plant control systems,facility DER energy management systems (EMS), building EMS, campus EMS, community EMS,microgrid EMS, etc. DA equipment includes equipment used to manage distribution circuits, includingautomated switches, fault indicators, capacitor banks, voltage regulators, and other power managementdevices.The IEC 61850 DER information model standard utilizes existing IEC 61850-7-4 logical nodes wherepossible, while defining DER and DA specific logical nodes to provide the necessary data objects forDER and DA functions, including for the DER interconnection grid codes specified by various countriesand regions.Although this document explicitly addresses distribution-connected resources, most of the resourcecapabilities, operational functions, and architectures are also applicable to transmission-connectedresources.
