PV-HESS fed BLDC Driven Water Pumping System with PSO-based MPP Tracking Employing Zeta Converter

The increased importance of renewable sources in the field of automotive sector entails the use of solar photovoltaic (PV)-fed water pumping system driven by a brushless DC (BLDC) motor drive. To overcome the drawback associated with the conventional DC-DC converters, a zeta converter is employed to optimize the power processing. The maximum power is extracted from the solar array by controlling the duty cycle of zeta converter through particle swam optimization (PSO) based maximum power point tracking (MPPT) algorithm. To mitigate the PV output variation, hybrid energy storage system (HESS) is integrated to the PV system which inturn maintains the constant voltage at the input of BLDC motor drive. A robust power management algorithm is employed for proper control of PV-HESS system. The overall MPPT with power management control facilitates the zeta converter to meet smooth performance of the water pumping system. The performance of the proposed controller is demonstrated using MATLAB/Simulink for variation in atmospheric condition and Xilinx system generator control platform interfaced with Zynq ZC-702 FPGA kit.
