Design of Control Algorithm for Renewable Energy Resources

Abstract

The need for renewable energy sources is on the rise because of the subtle energy crisis in the world today. By the year 2020, India plans to produce atleast a minimum of 20 Gigawatts of Solar power, whereas we have only tapped less than half a Gigawatt of our potential as of March 2010. Solar energy is an important untapped resource in a tropical country like ours. The main obstruction for the penetration and reach of solar PV systems is their high capital cost and low efficiency. In this thesis, we examine a schematic to extract maximum obtainable solar power from a PV module and use the energy for DC and AC application also tackling with the problem of partial shading in PV. This project also uses the concept of Maximum PowerPoint Tracking (MPPT) which significantly increases the efficiency of the solar photovoltaic system. But in this project our main intention is to interface the PV array with the MPP tracker and process power for dc and ac loads. All simulations are carried under MATLAB/Simulink environment.
