Abstract

Numerous converters enhance the flexibility and manageability of the Grid-Connected Converter (GCC) within a DC/AC microgrid, facilitating the smooth incorporation of renewable energy sources. To capitalize on the power generation from photovoltaic (PV) modules and the wind turbines MPPT technique is employed. A DC voltage regulator is used in the layer of primary control to sustain a stable voltage profile. A coordinated control strategy integrates a grid-connected solar and wind power generation system with electric vehicle (EV) charging stations, balancing AC-DC loads with the support of a battery storage system. The solar PV system incorporates a boost converter with a Circle Search MPPT algorithm to optimize power extraction. The combination of wind and solar energy improves system reliability, ensuring renewable power supply for EV charging and household loads. The Power quality issues, such as the voltage sags and swells, are mitigated using a Distributed Power Flow Conditioner (DPFC), which enhances overall power quality and confirms stable procedure of the distribution system. The proposed system is tested in a MATLAB/Simulink environment, where the control strategy effectively balances loads, optimizes power delivery, and improves power quality under varying conditions.

Keywords: DC/AC Microgrid, Battery Energy Storage System, Circle Search Algorithm Coordinated Control, Photovoltaic Energy, Wind Energy.
