Abstract

In this paper, the transient response characteristics of microgrid containing virtual synchronous generator (VSG) and synchronous generator (SG) and their coordinated control methods under load fluctuations when they operate together are investigated and the instability in the transient process caused by the different mechanical structures and operation modes of heterogeneous micro-sources is analyzed. On this basis, a coordinated control strategy of SG-VSG based on power coupling is proposed to effectively reduce the overshooting and oscillation in the active power and frequency of the VSG. Meanwhile, in a microgrid containing energy storage, a low-pass filtered hybrid energy storage coordinated control strategy considering power equalization within the system is proposed to improve the power regulation capability and frequency stability of the system based on the principle of energy conservation at the input and output sides of the inverter. Finally, the proposed strategy is verified on the MATLAB/Simulink simulation platform.
