A microgrid is composed of distributed power generation systems, distributed energy storge systems, loads as a small scale power system. Generally, the microgrid is operated by an energy management system (EMS)
. In this paper, a testing technique for a microgrid EMS using the hardware-in-the-loop simulation (HILS) technique is introduced. Especially, the microgrid is composed of multiple buildings and each building has a combined heat and power (CHP) generator, a photovoltaic (PV) system, a heat only boil (HOB) system, electrical load, and heat load. In addition, electrical and heat energy each building is managed by a building energy management systems (BEMS). The microgrid EMS manages total electrical and heat energies of the microgrid by cooperation with each BEMS. To show validation of the proposed testing technique based on the HILS technique, a HILS system is developed and is tested.
Keywords: Microgrid, building energy management system (BEMS), energy management system (EMS), hardware-in-the-loop simulation (HILS)
