ANALYSIS OF INCREMENTAL CONDUCTANCE AND PERTURB AND OBSERVE METHODS OF MAXIMUM POWER POINT TRACKING FOR PHOTOVOLTAIC SYSTEM

Abstract

Maximum Power Point Tracking (MPPT) algorithms are significant in solar systems because PV systems have non-linear behavior and its power is dependent on solar irradiations. MPPT algorithms are utilized to exploit the efficiency of solar generators and shrink the photovoltaic array cost by decreasing the number of photovoltaic panels essential to attain the chosen solar output power. This paper signifies comparative experimental results of two main MPPT algorithms particularly perturb and observe and incremental conductance. These algorithms are popularly used as its benefits are its low-cost and easy to implement. Some vital constraints such as voltage, current and power output for each special combination have been traced for both algorithms. Hardware experimental design is been implemented for performance investigation of both the algorithms by a 50W photovoltaic (PV) array.
