Comparison of IC and P&O algorithms in MPPT for grid connected PV module

In the last decade, the use of renewable energy resources instead of fossil fuels pollutants has increased exponentially. Photovoltaic energy generation is ever more important as a renewable resource since it does not cause in fuel costs, pollution, maintenance, and emitting noise compared to other renewable resources as more accessibility of solar irradiation. In this paper, The Maximum Power Point Tracking (MPPT) controller for boost converter based on Perturb and Observe control is developed and compared to conventional tracking algorithm Incremental Conductance. The different steps of the design of these controllers are presented together with its simulation. The whole system is simulated under standard climatic conditions (1000 W/m2, 250C) in MATLAB and the irradiance is varied from 600 W/m2 to 900 W/m2. Results of this simulation shown that the system with MPPT using P&O controller increase the efficiency of energy production from PV.
