Abstract

Photovoltaic power generation system can not participate in the friendly interaction of power grid because of the lack of inertia damping. Virtual synchronous Generator（VSG） technology is an effective means to solve this problem. However, moment of inertia of technology based on virtual synchronous machine set is too large or too small are not conducive to the stability of the system frequency, based on the analysis of virtual synchronous machine running mechanism, this paper proposed virtual synchronous machine inertia adaptive control strategy, according to the load disturbance caused by frequency variation, the real-time dynamic adjust the moment of inertia, and thereby avoid frequency rapidly rising and falling. Finally, the effectiveness of the theoretical analysis is verified by MATLAB/Simulink simulation.
