【 摘 要 】

In this paper, virtual synchronous generator (VSG) model based control of photovoltaic power generations (PVs) for power system stability improvement is proposed. Different from other studies on VSG, a large-scale power system is the main target of the proposed control. Therefore, digital simulations are conducted using the IEEJ WEST 10-machine System Model, which is a typical large-scale power system model in Japan. In this power system, the system stabilization effect of the control is verified. In addition, the storage capacity of the energy storage device in PV required for achieving the control is evaluated. The simulation results show that the proposed control is more effective for the system stability improvement than the constant power control of the PV. In addition, it is shown that AVR function of the VSG model based control is necessary in the power system with poor voltage stability.
