Abstract

Photovoltaic energy has been widely studied and applied in the power grid in recent years due to its sufficient cleanliness and resource adequacy. However, the increase in photovoltaic penetration rate will also threaten the safe operation of the system. This paper establishes a photovoltaic system model and a microgrid model based on DIgSILENT to quantitatively study the photovoltaic system characteristic curve considering the influence of environmental parameters, and conducts research and analysis before and after the photovoltaic system is connected to the grid and participates in frequency modulation. The simulation results show that the photovoltaic system model and frequency regulation strategy established in this paper have practical value.
