Summary The conventional upstream/downstream protection coordination approach and master/slave information communication method in radial distribution network can no longer satisfy the protection requirement in a microgrid because the loads and distributed energy resources (DERs) have stochastic characteristics and the topology of a microgrid changes over time. In the proposed microgrid protection architecture, to have the intelligent protection intelligent electronic devices (IEDs) with IEC 61850 communication protocol is applied regardless of grid‐connected mode or islanded mode operation. Furthermore, real‐time generic object‐oriented substation events (GOOSE) messages and adaptive protection strategies are used. Finally, the feasibility and effectiveness of the proposed microgrid protection scheme are verified through the artificial faults conducted a testing microgrid built in the Institute of Nuclear Energy Research (INER) of Taoyuan, Taiwan.
