DESIGN AND IMPLEMENTATION OF CROW SEARCH ALGORITHM TUNED MPPT CONTROLLER FOR GRID CONNECTED PV SYSTEM

Abstract

Abstract: This paper presents the Crow Search Algorithm (CSA) based Maximum Power Point Tracking (MPPT) scheme for solar PV system integrated with utility grid. Incremental conductance based MPPT is used in PV system and its limitations will be overcome by introducing Integral regulator at the grid side. In this work, CSA has been implemented to tune the gain values of the integral regulator at source side and that of the DC voltage regulator at grid side simultaneously based on an optimization criterion for minimizing power error in source side. The static and dynamic power tracking capability of the proposed technique is tested in MATLAB simulation under constant load with variable irradiation conditions.
