Optimization of Solar Photovoltaic Water Pumping System

Solar Photovoltaic Water Pumping System, as an integrated system of PV, Variable frequency drive and pumping system, which deals with the simulation and design of an effective pumping system. Thus the techniques of modeling and photovoltaic theoretical studies can be obtained by using equivalent circuits. The system also includes the maximum Power point tracking (MPPT), which can add efficiency to the total system. This paper presents the effective way to optimize the Solar photovoltaic Water Pumping System (SWPS) through both by simulation and by using a practical setup and thus evaluating the whole system performance. However the system also includes DC-DC converters for the proper voltage conversion and operation. Thus the whole SPWS system is being simulated through MATLAB, so the comparative study can be done on the performance of the system. Here the simulation in MATLAB verifies the system and MPPT functionality. Incremental Conductance (IC) method is used for maximum power point tracking (MPPT). The maximum Power variation is due to both irradiance and temperature. Since the conversion efficiency of PV Array is very low, it requires maximum Power point tracking (MPPT) control techniques. Thus every VFD’s will power with MPPT Technology. This basically deals with Total System evaluation, which will be optimized based on the obtained water output for the given DC Power input.. The simulation results were carried out to verify the effectiveness of the proposed Scheme improved the performance of the systems.
