Back-to-Back Voltage-Source Converters with PSO-based PI Tuning Controller for Grid-Connected Wind-Solar Cogeneration

Abstract

The main aim of this project is Back-to-Back Voltage-Source Converters with PSO optimized PI Controller for Grid-associated Solar/Wind Cogeneration to reach the desired performance level. An effective and simple wind-solar cogeneration system has been proposed in this research. Utilizing BtB VSCs with PSO -PI controller tuning, a wind turbine is connected to the grid. A dc-link capacitor was used to directly connect a PV generator. There are no phase’s conversion of DC/DC in this system. In addition, to maximize the extraction of renewable energy, the proposed topology incorporates tracking of the individual maximum power points of PV and Wind generators. A Particle Swarm Optimization (PSO) based PI controller with vector control in a rotating reference frame is used to control the VSCs. The suggested system's performance is also examined in light of utility-grid issues. MATLAB/SIMULINK findings are used to verify the proposed topology's efficiency.
