In primary frequency regulation (PFR) using battery energy storage system (BESS), the droop configuration for BESS needs to be considered thoroughly. This paper modified the traditional droop configuration method by considering more BESS`s internal nonlinear constraints and then proposed a variable droop strategy for operation. By doing this, a modified BESS model for PFR was constructed. Finally, the validity of BESS droop configuration method in this paper is testified with a three-area equivalent model based on the data of actual grid. The results show that variable droop strategy is more suitable for PFR than fixed traditional one.

Lithium-ion battery energy storage technology has recently made great development, which can play a significant role in power system. Take grid load shifting for example, lithium-ion battery energy storage technology can alleviate the problem of the growing difference between peak and valley, and reduce power system equipment investment, etc. While the high cost of lithium-ion battery energy storage technology limits its large-scale application at present stage. Hence, during early stage of energy storage project investment planning, it is necessary to analyze the economic problems of its investment. Based on the technical level of the lithium-ion battery at present, lithium-ion battery energy storage system capacity configuration strategy is proposed and economic analysis model is established. Finally, economic issues of investment in lithium-ion battery energy storage system for grid load shifting are studied, and the capacity configuration recommendations are given.
