Abstract:
In this article novel fast sweeping method is proposed as MPPT for PV fed water pumping system. Solar photovoltaic (PV) array which is exposed to the uniform solar irradiance shows the non-linear P-V characteristic. Though, the P-V characteristic becomes further complex with numerous maximum power points (MPP) when the array is functioned in partially shading condition. PSC results hotspots, power loss and reduces the reliability of the solar power generation system. Furthermore PV characteristic curves of solar panel array reveal several peaks. The main disadvantages of traditional MPPT methods are that they are unable to track global peak under non-uniform irradiance/insolation. Under this condition traditional MPPT methods frequently are unsuccessful to provide optimum MPP. In this paper novel Fast sweeping method is proposed as MPPT to track global MPPT. The performance of proposed MPPT is compared with existing intelligent controllers such as Fuzzy logic controller, artificial neural network controller and adaptive Neuro Fuzzy inference system based MPPT in a partial shading condition. Entire system is analysed using Matlab. Experimental analysis is done to validate the simulation.
