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.
