Design and validation of a single-phase buck–boost inverter with Grey Wolf optimization algorithm under partial shaded conditions

Abstract

The key intention of this research article is to design and validate a single-phase buck–boost inverter which can be utilized to modify DC power from solar panel to AC power without the need of a DC-DC converter. The proposed topology is designed to perform Maximum Power Point Tracking (MPPT) directly and the output from the inverter can be used for standalone load or can be integrated with grid. In this paper, a Global Maximum Power Point Tracking (GMPPT) is executed to gain maximum power under the Partial Shading Conditions (PSC) of solar panel. GMPPT is tracked instantaneously using Grey Wolf Optimization (GWO) technique. The proposed work is successfully carried out using MATLAB software and a prototype model is developed to validate the simulation results.
