MPPT controller for a photovoltaic power system based on increment conductance approach

This paper deals with the power optimization problem in photovoltaic generators. Indeed the nonlinear characteristic of photovoltaic generators [1], leads to search for a solution to track the maximum power provided by the PV array in order to exploit well the energy. A maximum power point tracking algorithm based on an approach called increment conductance control of photovoltaic systems is well detailed in this paper. It provides good performance against the different variation of climatic conditions and load. Simulation results prove that this algorithm can effectively attend the maximum photovoltaic power´s production.
