Modeling and Simulation of Incremental Conductance MPPT Algorithm for Photovoltaic Applications

Photovoltaic (PV) is a technical name in which radiant (photon) energy from the sun is converted to direct current (dc) Electrical Energy. PV power output is still low, continuous efforts are taken to develop the PV converter and controller for maximum power extracting efficiency and reduced cost factor. The maximum power point tracking (MPPT) is a process which tracks one maximum power point from array input, varying the ratio between the voltage and current delivered to get the most power it can. A number of algorithms have been developed for extracting maximum power. This paper details the study of incremental conductance MPPT algorithm. And it can be experimentally verified by modeling the PV system with MPPT algorithm in Matlab/Simulink Software.
