Design and Analysis of Maximum Power Point Tracking (MPPT) based Solar Powered Battery Charging System

Abstract

Continuous efforts are being made to make PV panels more efficient where Maximum Power Point Tracking (MPPT) algorithms are an important part of modeling of renewable energy utilization. Advances are being made in the design as well as material which can affect the efficiency of PV panels. Aim of this project is to implement different MPPT algorithms to PV panels and do comparative analysis of the results. The temperature and irradiance are significant parameters to be governed for a PV panel's performance. The output power of the PV keeps changing with respect to the changing weather conditions. To get maximum and continuous power, DC-DC boost converter has been used along with the MPPT algorithm. The duty ratio of DC-DC converter is controlled by the MPPT algorithm and apparently the output power of the PV panel will be controlled. The output power of the PV panel hasibeen utilised to charge battery. Simulation and analysis of Perturb and Observe P&O and Incremental Conductance(INC) has been carried out using simulation software.
