Hybrid Renewable Energy System Control Comprising Wind Turbine System, Photovoltaic Panels System, and Battery Energy Storage System

This study focuses on enhancing the power quality of a renewable hybrid energy system (RHES) that integrates wind turbine (WT), photovoltaic (PV), and battery storage (BS) technologies. These components are linked together using a DC/DC converter, and a multifunctional voltage source inverter (MFVSI), which ensures a stable operation of the electrical grid while supporting a nonlinear load. The MFVSI plays a critical role in improving reactive power and mitigating harmonics in the power network. To maximize energy conversion efficiency, Maximum Power Point Tracking (MPPT) algorithms are applied to both the wind and solar energy systems. The battery storage is managed through a bidirectional DC/DC converter. For optimal control of the active (P) and reactive (Q) power flow, the system employs an advanced Direct Power Control (DPC) strategy within the Grid Side Converter, effectively managing power exchange with the grid under varying conditions. Finally, the simulation of this study was conducted using MATLAB Simulink to acquire the best results.
