Comparative study of maximum power point tracking methods for photovoltaic system

Abstract

Maximum Power Point Tracking (MPPT) is one of the important part of photovoltaic system, which the output power and efficiency of photovoltaic system. A comparative study between perturb and observe (P&O) based on PID controller and incremental conductance (IC) base on PID controller verified in this paper. To verify the response of the MPPT methods under changing solar irradiance and temperature a simulation have been established by MATLAB/Simulink. Experimental study was established to test the response of both algorithms to solar radiation changes, also to compare between to the two algorithms.
