Design and Implementation of an Isolated Solar Photovoltaic Power Generation System

Abstract

Solar photovoltaic power generation system is one of the burning research fields these days, even governments are also making plans toward increasing the amount of power generation from renewable energy sources because in future viability and crisis of conventional energy sources will increase. Further government liberalization and technical developments encourage the use of renewable sources for power generation in terms of distributed generation system. In order to rigging the present energy crisis one renewable method is to develop an efficient manner in which power extracts from the incoming son light radiation calling Solar Energy. This thesis deals with the design and hardware implementation of a simple and efficient solar photovoltaic power generation system for isolated and small load up to 5 KW. It provides simple basic theoretical studies of solar cell and its modelling techniques using equivalent electric circuits. Solar Photovoltaic (PV) power generation system is comprising several elements like solar panel, DC-DC converter, MPPT circuit, Battery charge controller and load, these subsystems are designed in Proteus software and DC-DC (Boost) converter, MPPT circuit using microcontroller and sensors adopting perturbation and observation method, Battery charge controller and single phase inverter for AC loads are implemented in hardware in simple manner.
