FRACTIONAL ORDER CONTROL FOR MAXIMUM POWER POINT TRACKING OF PHOTOVOLTAIC SYSTEMS

Abstract

Summary: Green energy sources including solar energy, wind energy, tidal energy, and biomass have attracted considerable attention in recent years due the diverse methods and their renewable nature. Solar energy is attractive, because it directly converts solar radiation energy into electricity. Its energy conversion and control system are simple and easy to maintain. Under various atmospheric conditions, automatic MPPT is essential to maintain maximum output power for different types of PV systems. The main objective of this research is to Develop a fractional adaptive control which will be applied to optimize the PV cells output power in order to enhance the control system performances. Optimization of fractional controller parameters for good tracking characteristics and make a comparative analysis between different methods to get MPP.
