TPQA: Three point quadrature approximation MPPT algorithm

Abstract

Growing concerns about environmental issues and the world energy crisis have attracted a great deal of interests for the development and application of the photovoltaic (PV) power system that uses the nonpolluting and the most abundant solar energy. This paper introduces a novel maximum power point tracking (MPPT) algorithm that is based on the fact that the PV power curve is similar to a parabolic curve in nature. The algorithm is implemented and validated on Simulink/MATLAB. The simulation results show enhancement in tracking time and accuracy in comparison to the Perturb and Observe (P&O) algorithm.
