Performance Analysis of 250kW Grid-Connected Photovoltaic System

The utilization of renewable energy sources such as solar and wind power for the creation of electrical energy has become increasingly prevalent in response to the growing demand for electricity. The incorporation of renewable energy sources into the system is crucial for efficient energy consumption. Directly injecting power from renewable energy sources into the grid is a challenging task. Therefore, the system requires power electronic inverters to serve as a connection between renewable energy sources and the grid or load. This research examines the performance of a 250 KW grid connected to a solar system under three different input source scenarios. The inverter generates a clean sinusoidal voltage of 415 V in three phases, which is then used to supply power to the grid and the three-phase load. This study offers several additional benefits, including reduced switching losses, decreased voltage stress of dv/dt on switches, and improved electromagnetic interference. The MATLAB/Simulink software is used to simulate and evaluate the performance of a 250 KW grid. The accuracy of the results will be confirmed.
