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.

The high proportion of renewable energy sources (RESs) in the system reduces the frequency support capacity and aggravates the generation of unbalanced power, while the dynamic frequency dispersion makes it difficult for a centralized energy storage system (ESS) to take into account the frequency requirements of different regions. In this context, the research takes the region with high penetration of RESs and frequent power fluctuations as the grid node of the ESS. By configuring the parameters of the ESS under the control strategy of virtual synchronous generators, the inertia and the primary frequency reserve of the system are supplemented, and the regulation characteristics of the ESS are depicted. Taking the steady-state recovery time and the amplitude coefficient as the evaluation indexes, the effects of the virtual inertia constant, the virtual damping coefficient, and the virtual frequency regulation coefficient on the behavior of the ESS are deeply analyzed. Finally, the quantitative configuration of the ESS is realized by considering the frequency response and the dynamic frequency dispersion.
