  4. 4. MicroGrids are defined according to the IEEE Std 1547.4-2011  Guide for Design, Operation, and Integration of DR Island Systems with EPS. The term DR island systems, sometimes referred to as microgrids, is used for electrical power systems (EPS) as: 1. Have DR and load 2. Have the ability to disconnect from and parallel with the area EPS include the local EPS and may include portions of the area EPS, and 3. Include the local EPS and may include portions of the area EPS, and they are intentionally planned. DR island systems can be either local or area EPS islands 4 Microgrid Research Programme – ET – AAU 4
