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.
