An Assessment Of The Implementation Of Mppt Algorithm For Pv Pumping Based On Perturb And Observe Logic (P&O) Controller

Abstract

Solar cells convert solar light into electricity, but their major drawbacks include high initial costs, low photo conversion efficiency, and unreliable power generation. The maximum power point (MPP) of solar cells depends on solar insolation level and temperature, which causes the current-voltage characteristics to vary. Utilizing an MPPT technique to maximize the production of power from solar panels is among the most interesting areas of research in photovoltaic (PV) systems.The main parts of the PV system consist of PV panel, converter, controller and load. Converter and controller play a major role in the system. Controller is used to extract the maximum power from the PV panel. In this paper, a suitable converter topology to extract maximum power is suggested and performance of the converter is also tested with P&O fuzzy logic controller. The performance of the proposed controller and converter topology is appraised with conventional boost converter topology in terms of output power. It confirms that the proposed topology performed better than the conventional boost converter. The results show that the designed MPPT controller improves the efficiency of the PV panel when compared to conventional charge controllers.
