This guide covers the design and selection of protective devices and the coordination between them for various modes of operation of the microgrid. These include grid-connected and islanded modes and transitions between modes.

This guide facilitates the deployment of protection systems, given the challenge of protecting equipment and assets in the microgrid’s different modes of operation, including grid-connected or islanded modes and during transitions between modes. The guide proposes different approaches, centralized and decentralized, passive and active, to detect and take proper actions to dependably and securely protect the microgrid and its equipment.

New IEEE Standard - Active. A microgrid control system and a microgrid protection system are required for microgrid deployment. The nature of the microgrid assets, which may include a significant amount of distributed energy resources, and the modes of operation, either grid-connected or islanded, need to be considered in the design of both systems. The design and selection of protective devices and their coordination for the microgrid’s different modes of operation are covered by this guide. Different approaches to detect and take proper actions and to dependably and securely protect the microgrid and its equipment are proposed.
