Performance Evaluation of a Grid Connected Hybrid Microgrid Using ANN Based PWM Control

The proposed work presents a performance analysis of a grid-connected hybrid microgrid integrating wind and solar energy sources. The system enables optimal utilization of renewable resources through adaptive MPPT control combined with the conventional perturb and observe method. Depending on resource availability, the wind and solar units can supply the load individually or simultaneously. In the wind subsystem, turbine rotor speed governs mechanical power extraction, while in the solar subsystem, the operating voltage of the PV array determines output power. A Permanent Magnet Synchronous Generator (PMSG) is coupled with the wind turbine for efficient energy conversion. The inverter converts the DC outputs of both renewable sources into usable AC power for grid connection. To minimize harmonic distortion, an ANN-based PWM control strategy is employed. Simulation results validate the operational feasibility, effective power transfer, and reliability of the hybrid system under normal environmental conditions.
