REliable energy supply and voltage control for hybrid microgrid by pid controlled with integrating of an EV charging station

Abstract

The integration of an electric vehicle (EV) charging station into the DC-microgrid requires management control of the energy supply and the voltage variation. The hybrid energy sources of the microgrid consist of battery storage, wind energy, and photovoltaic (PV) energy sources. To optimize power generation from renewable energy sources such as wind and PV, the source-side converters (SSCs) are regulated by the leading edge intelligent PID technique. This strategy enhances the quality of power delivered to the DC-microgrid. The microgrid comprises AC/DC loads, battery storage, EV charging stations, backup power from the main grid, and renewable energy supplies comprising wind and solar energy. The proposed control system relies on monitoring the state of charge of the battery and utilizing renewable energy sources to supply loads efficiently. The final results of the simulation obtained from the simulation software MATLAB and Simulink are used to validate the effectiveness of the suggested energy control technique, which performs well in terms of accurate control and maintaining a stable energy supply even under various load and weather conditions.
