Solar Frame to Track Power Utilizing Power Decoupling Method with Particle Swarm Optimization

Abstract

In this work, solar PV panel is connected to single phase grid through converters. Dc-Ac inverter is taken to flow ac output to grid. Due to shading of solar radiation on string, we see mismatch of power. Maximum power is tracked at each string with changes in temperature and irradiance. This discrete power can be modified by using converters with P and O method. Full power processing converters are the existing solutions where the power is processed directly and we notice more losses. Boost converter is used to raise the output of panel, which is very low due to shading and it is proposed scheme. There are many techniques used to observe the power from the system. The entire circuit design and process done in MATLAB software. The results indicate that the proposed Particle Swarm Optimization (PSO) setup is very efficient, very simple and low cost.
