Realization of PV Power Structure with PSO Tuned Fuzzy Logic Control

A hybrid optimal control has been considered for renewable energy systems in this paper. The Maximum Power Point Tracking (MPPT) control is achieved by combining the Particle Swarm Optimization and Fuzzy Logic Control (PSO-FLC). The system employs a ZETA converter with MPPT for utilization of dc-link voltage under different irradiance levels. The proposed system supplies AC power to the grid and thus locates the MPP of the photovoltaic (PV) array globally. The PSO algorithm is employed to accurately optimize the fuzzy values. The proposed PSO-FLC topology is realized in the MATLAB/Simulink environment, and then integrated with the PV array for real-time implementation. The presented results validate the proposed hybrid approach.
