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.
