확장성을 고려한 전지전력저장장치 연구

The BESS is composed of Battery Package, PCS(Power Conditioning System) Package, BCU(BESS Contorol Unit). In Jeju smart grid test-bed, we have developed a business model by BESS power system, renewable energy, transportation, such as customers, and have demonstrated above things. We have analyzed the EMS(Energy Management System) model of KPX where manages supply and demand of domestic electrical power system. We modified and launched EMS for microgrid but the cost was expensive and the system was large size. For releasing this system from industry as a whole, it is imperative to develop PMS(Power Management System) for microgrid. However, the cost of EMS for microgrid is expensive , some systems because it is a large development of the all of the first fruits in urgent PMS(Power Management System) for microgrid to be used in industry in general. Therefore, in this paper, we propose the BESS model considering the power systems charateristics and extensibility in korea. and also we propose the the PMS to manage the BESS systems.
