Optimal control for a photovoltaic integrated grid system using PSO and modified whale optimization to enhance power quality

Abstract The paper proposes a modified & optimized controller for PV-integrated grid-connected PV systems. As the solar power output depends on environmental conditions, i.e., irradiation and atmospheric temperature, maximum from photovoltaic (PV) module is extracted using perturb observe (P O) algorithm. With variety of controllers, such as conventional proportional integral (PI) particle swarm optimization (PSO), Whale algorithm (MWOA) method based optimum control, compared to panels MWOA-based controllers. A complete simulation implementation single-phase inverter are shown verify proposed controller. flow control grid synchronization also presented when above controllers act MPPT in system. performance system evaluated among optimal under MATLAB-Simulink environment.
