Part 7-420 - Distributed energy resources and distribution automation logical nodes

After tremendous work on the revision and extension of the IEC 61850-7-420 Edition 1, IEC TC 57 just published the 366 page committee draft IEC 61850-7-420 ED2:


Communication networks and systems for power utility automation – Part 7-420: Basic communication structure – Distributed energy resources and distribution automation logical nodes

Commenting period closes 2018-08-17

Excerpt from the introduction:

"Increasing numbers of DER (distributed energy resources) systems are being interconnected to electric power systems throughout the world. As DER technology evolves and as the impact of dispersed generation on distribution power systems becomes a growing challenge – and opportunity – nations worldwide are recognizing the economic, social, and environmental benefits of integrating DER technology within their electric infrastructure.
The manufacturers of DER devices are facing the age-old issues of what communication standards and protocols to provide to their customers for monitoring and controlling DER devices, in particular when they are interconnected with the electric power system. In the past, DER manufacturers developed their own proprietary ...

This document addresses the IEC 61850 information modelling for DER, although some types and aspects of DER information models have been developed or are being developed separately through technical reports before they are added to this international standard DER model. These consist of the following:
• IEC 61850-90-6: Use of IEC 61850 for Distribution Automation Systems
• IEC 61850-90-8: Object model for electric mobility
• IEC 61850-90-9: Use of IEC 61850 for Electrical Storage Systems
• IEC 61850-90-15: DER Grid Integration using IEC 61850 "

This document is one of the crucial parts for the application of IEC 61850 in distributed power systems.
