Abstract
AbstractThe Sun energy radiating on the earth's surface is in the form of direct and diffuse radiation. Solar photovoltaic is an energy conversion technique, which converts solar radiant energy directly into electricity using solar PV panel. Solar radiation coming onto the solar panel, both direct and diffuse are variable in nature. Due to this, power produced by solar photovoltaic is also variable. To track maximum power from the available radiant energy, a maximum power tracker is required. Maximum power point tracker having fixed step size is not accurate and it oscillates below the true maximum powerpoint. For optimum maximum power tracking, a large step size beyond the maximum power point tracking zone and a small step size within the tracking zone is required. In this paper, a variable shrinking step size maximum power point tracking technique for the Incremental Conductance controller-based boost converter based on the concept of fix and variable power slope region method is employed. It also compares the performance of the universally adopted Incremental Conductance method.KeywordsSolar PVRenewable energyMaximum power point trackingBoost converterIncremental conductance
