Solar Photovoltaic based Brushless DC Motor Driven Water Pumping System using PSO-MPPT Algorithm

In this paper, analysis of Solar Photovoltaic (SPV) powered brushless dc motor driving water pumping system is presented. The power-voltage (P-V) wcurve of SPV array contains a large number of local maximum power points (MPPs) and one global point (GP). To find the global point of maximum power, a particle swarm optimization (PSO) technique is used. PSO based MPPT technique has proven better performance in contrast with the conventional P&O for the BLDC motor-water pump. A dynamic and steady-state examination of BLDC motor with Cuk converter has been carried out. The simulation in MATLAB/SIMULINK shows the faster tracking speed with PSO based MPPT technique in comparison with P and O. In addition to this oscillation at the operating point of maximum power is observed to be less. The hardware results will be available at the final version of this manuscript.
