An Improved Energy Management Strategy for a DC Microgrid with Electric Vehicle Fast Charging Stations Using Fuzzy Logic Control

This extension of the original study presents the incorporation of a fuzzy logic controller (FLC) into the control strategy for the DC microgrid, further enhancing the integration of the electric vehicle fast charging station (EVFCS) and distributed generation units. The fuzzy controller is employed to optimize the operation of the system by providing adaptive control for voltage regulation, improving the performance of the distribution static compensator (D-STATCOM) device, and ensuring more efficient interaction between the EV battery and the grid. The results, obtained through MATLAB Simulink/SimPower Systems simulations, demonstrate that the FLC improves the system’s ability to handle voltage fluctuations, reduces charging durations, and enhances grid stability, particularly under varying load and generation conditions. The extension showcases how the fuzzy controller enhances the overall efficiency of the EVFCS, making it a more reliable and flexible solution for modern grid applications, especially in the context of vehicle-to-grid (V2G) technology.
