Abstract: An environment-friendly, efficient and simple control method for solar photovoltaic (PV) and wind-based water pumping system using brushless DC (BLDC) motor drive and battery storage is proposed in this paper. This technology provides continuous water pumping under different climate conditions. By using perturb and observe (P&O) maximum power point tracking (MPPT), the solar PV and permanent magnet synchronous generator (PMSG)-based wind energy conversion system (WECS) generate maximum power, and feed it to a common DC bus. The power is delivered to a BLDC motor that operates the water pump. The motor speed and the battery charging are controlled, and the DC bus is always maintained at fixed voltage. Power generated by solar PV and WECS is delivered to charge the battery using a single-ended primary-inductor converter (SEPIC)-based charge controller if water pumping is not demanded. In MATLAB, the proposed model is developed and simulated, and demonstrated under various operating conditions.
