Abstract :

The Grid-connected EV Charging Station Integrating A Photovoltaic (PV) Array And Battery Energy Storage System (BESS) To Enhance Energy Reliability And Efficiency. A Fractional-Order Proportional-IntegralDerivative (FOPID) Control Strategy Is Employed To Optimize Power Flow, Ensuring Stable Grid Interaction And Effective Energy Management. In This Project, A Charging Station For Electrical Vehicle (EV) Integrated With A Battery Energy Storage (BES) Is Presented With Enhanced Grid Power Quality. The Positive Sequence Components (PSCs) Of The Three Phase Grid Voltages Are Evaluated For The Estimation Of The Unit Templates (UTs) And The Reference Grid Currents. The EV And BES Are Connected At Dc Link Using A Bidirectional Buck-boost Converter. During The Daytime, EV Takes Power From The Solar Array, While In Its Absence, It Consumes The Power From The Grid. The Proposed System Mitigates Grid Dependency By Maximizing Renewable Energy Utilization And Leveraging Battery Storage For Peak Load Management. Simulation Results Demonstrate The Effectiveness Of The FOPIDbased Control In Improving System Stability, Voltage Regulation, And Overall Performance Compared To Conventional Controllers. This Research Contributes To The Advancement Of Smart And Sustainable EV Charging Solutions. Tests Are Conducted On A Software Developed In The MATLAB/SIMULINK For The Validation Of The Satisfactory Response Under Different Dynamics Conditions. Key Words-- Photovoltaic (PV) Array, Battery Energy Storage (BES), Voltage Source Converter (VSC), Bidirectional DC–DC Converters, Digital Signal Processor, Fractional Order PID Controller (FOPID)..
