A Novel Computational Approach towards Maximum Power Point Tracking for Solar Photovoltaic and Wind Energy Systems

Abstract:

In this paper a new approach for maximum power point tracking (MPPT) is proposed. The fractional open circuit voltage based MPPT states that the photovoltaic (PV) array voltage corresponding to the maximum power gives a linear dependence with respect to array open circuit voltage for different irradiation and temperature levels. This method is the easiest and simplest of all the MPPT methods but the disconnection of the PV array from the load on regular intervals for the sampling of the array voltage causes significant power loss. A new and simple approach is proposed by the simple linear equation of line for calculating the duty cycle of the boost converter which will extract the maximum power for the particular radiations. This topology can also be used for Wind energy systems but here the simulation is done with solar photovoltaic only. The proposed work is verified using MATLAB/SIMULNK and simulation results shows a clear improvement in achieving the desired results.
