Maximum Power Point Tracking (MPPT) Control of Grid Connected Solar-Wind Energy Conversion System

Grid-connected solar-wind energy conversion systems are distinguished by their dependability and operational efficiency. Modeling, simulation, and control of a system that converts energy from solar and wind and feeds it into the grid are described in this paper. The system contains of a wind turbine, a synchronous generator with permanent magnets, a solar array, a controller, and converters. An MPPT control technique with optimal tip speed ratio (OTSR) delivers maximum power in wind energy systems independent of variations in wind flow. The solar system’s highest power point is monitored with the use of the Perturb and Observe (P&O) Maximum Power Point Tracking (MPPT) algorithm. The control technique works on the inverter to keep the DC link voltage constant and controls the injected power to maintain the constant voltage and frequency fluctuations within the limit at the grid side. In the MATLAB/Simulink software, the suggested system’s dynamic behaviour and control are examined.
