Scheduling of an Energy Storage System Operation with Regard to the Market Price Behavior

This paper presents a decision-making tool that enables multifunctional operation of a battery energy storage system (BESS) in combination with renewable energy sources (RES). In the framework of the tool implementation the operation of the BESS in combination with solar photovoltaic panels was studied on the Green Campus of LUT University, Finland. The set-up was adjusted to work in the day-ahead and frequency regulation markets with a separate schedule for every season of the year. The results demonstrate the feasibility of establishing a software that enables operation of a BESS. The tests performed in the study indicate that the operation on the market of ancillary services is more profitable than in the day-ahead market.
