Abstract
In this paper, a PV array is used for water pumping purposes at remote or abandoned locations. This paper focuses, matching the on-site induction-motor (IM) pumping loads with the given PV power for the most optimal operation using maximum photovoltaic power tracking (MPPT) based on perturb and observe (P&O) algorithm and technique with dynamic error driven PI controllers is introduced. A PV array subjected to constant and variable solar irradiations is designed to feed a water pumping load driven by a 3-phase IM. A dc/dc boost converter, dc link capacitor, dc/ac, 3-arm, 6-pulse, 3-phase inverter are used as a power conditioning unit between the motor and PV array. The proposed inverter control selects the suitable operating point for PV voltage, current and power. MPPT based on perturb and observe (P&O) algorithm for the purpose of improving efficiency of the system is connected to the system. Simulation results demonstrate the operation of the unified system with and without controller under constant and variable solar irradiations. The main control objective is to run system as close as possible to the maximum power point operation under constant and variable solar irradiations.
