This paper deals with the study of different type of MPPT (Maximum Power Point Tracking) algorithms in a solar photovoltaic system (SPV) in order to extract maximum power from the solar modules. Here the solar array is integrated with the grid to provide power, as the traditional sources of power generation is depleting at a faster rate and also to provide power during peak hours in urban areas...

This Paper presents Maximum Power Point Tracking (MPPT) of Photovoltaic Array under partial shading condition. The power available at the output of photovoltaic cells keeps changing with solar insolation and ambient temperature because photovoltaic cells exhibit a nonlinear current voltage characteristic.

This paper presents a new direct maximum power point tracking (MPPT) with reference voltage (Vref) based on the metaheuristic earthquake algorithm (EA) where optimization variable is Vref for hard-switching converters. The efficiency and performance of EA-MPPT-Vref compared perturb-and-observe (P&O) counterpart technique due to fact that it widely used commercial products. Static dynamic re...

The maximum power point tracking (MPPT) in photovoltaic (PV) systems varies depending on the fluctuation of the solar radiation and temperature; while the energy transfer from the PV to the load is controlled by specific algorithms. Conventional techniques for MPPT (Perturb and observe (P&O)) are easy to implement but they suffer from oscillations at MPP and speed is less due to fixed perturb s...
