Control of Photovoltaic Grid Connected System Using Incremental Conductance Method

Abstract

The depletion of fossil fuel resources on a worldwide basis has necessitated an urgent search for alternative energy sources to meet up the present day demands. Solar energy is clean, inexhaustible and environment-friendly potential source among renewable energy options. Among the renewable energy sources, the energy thro’ the photovoltaic effect can be considered the most essential and prerequisite sustainable resource because of the abundance and sustainability of solar radiant energy. Regardless of the intermittency of sunlight, solar energy is widely available and free of cost. There are so many ways to generate electricity from solar energy. Recently, PV array system is likely recognized and widely utilized to the forefront in electric power applications. It can generate direct current electricity without environmental impact and contamination when is exposed to solar radiation. Being a semiconductor device, PV system is static, quiet and free of moving parts, and these make it have little operation and maintenance costs. The objective of this work is to study the control of photovoltaic grid-connection and power quality managements.
