풍력발전 연계 다목적 BESS의 실시간 운영을 위한 혼합정수선형계획법 기반 최적 충방전 전략

 Abstract Large thermal plants-based conventional power system has been changing the system structure to the distributed and decentralized one in which a various number of REs and ESSs are installed regionally. The change leads to new market policies and emergence of prosumer. There can be several considerations to operate the Wind-BESS hybrid system. For the prosumer’s perspective, maximizing operational profit can be one of the most prioritized goals. Another important thing to be considered is to control the output not to lead to severe frequency fluctuation in case of incident wind speed deviation. In this paper, two operation algorithms based on mixed integer linear programming are proposed. First scheme is the wind ramp-rate constrained economic operation. According to domestic RPS policy, the EMS provides the most profitable 1 day scheduling that does not exceed the limitation assigned by local grid code. Secondly, Peak shaving algorithm dispatching multiple BESSs is proposed. BESS resources will be able to lighten the system’s burden when certain local grids experience peak load. So the algorithm will dispatch applied batteries considering each performance, efficiencies and its physical limit. The output throughout this study could be references of BESS operation and controller. Also, the designing EMS with proposed algorithms are expected to maximize the advantages for both prosumer and grid operator.
