摘要：
In order to overcome the defects of virtual droop control and virtual inertia control, we proposed a comprehensive frequency regulation strategy with participation of battery energy storage (BES), which fully considered the regulation requirements in different frequency ranges, the respective advantages of two control methods, and capacity limitation of ES unit. Moreover, we analyzed the influence of virtual inertial control on system dynamic characteristics,which revealed that the inertial control could hinder the frequency recovery, then a virtual negative inertial control strategy was accordingly designed. Besides, to guarantee the maintaining performance of state of charge (SoC), we proposed an adaptive control method considering the SoC feedback. Finally, the proper deviation values were defined for choosing corresponding strategy according to system’s requirements. The proposed strategy is verified with a typical regional power grid on MATLAB, which includes scenarios of 1.5% step power disturbance and continuous disturbance within period of 20 min. The SoC performance is also assessed through the simulation results, proving the effectiveness of the strategy. © 2018, High Voltage Engineering Editorial Department of CEPRI. All right reserved.
