Abstract

The estimation of Maximum Power Point (MPP) of photovoltaic (PV) array is essential for integration of solar power to microgrid. This paper presents the estimation of Maximum Power Point of a solar photovoltaic array under different environmental conditions (i.e. different temperature and solar irradiation) using Levenberg Marquardt method. The estimation is done using the single diode based model parameters of photovoltaic (PV) module. The photovoltaic (PV) module parameters are estimated from the data sheet values given by manufacturer. The estimated Maximum Power Point (MPP) values of the PV array under different environmental condition are presented in the simulated current-voltage and power-voltage characteristics. It is demonstrated that the estimated MPP values of the PV array are nearly equal to simulated MPP values.
