摘要
With the development of renewable energy, the influence of photovoltaic power plant on power grid is increasing. In order to study the influence of large-scale photovoltaic power plant on power system, it is necessary to establish a centralized equivalent model of large-scale photovoltaic power plant composed of many power generation units to avoid the problem that simulation time is too long. In this paper, the detailed model of photovoltaic power generation unit including PV array, inverter and its control system is constructed. On this basis, the equivalent polymerization model of PV power plant and its parameter calculation method are deduced. Finally, for a real large-scale photovoltaic power plant in Shenmu, Shan Xi, through Simulink simulation software and RT-lab hardware-in-the-loop simulation platform, the method described in this paper is verified. The error analysis shows that the proposed method can accurately track the dynamic characteristics of photovoltaic power plant.
