Efficient Power Control in Hybrid Solar and Wind Energy Systems with Bidirectional Converter and Advanced MPPT Control

This study focuses on the development of a 1 kW hybrid solar/wind energy conversion system with a battery, utilizing a bi-directional converter to efficiently deliver power to the grid and local loads. A digital controller is employed to implement power control methods and enhance the system's energy utilization efficiency, reducing energy expenses. The proposed system integrates advanced Maximum Power Point Tracking (MPPT) algorithms and a bidirectional converter system modeled using Matlab Simulink, specifically incorporating Buck-Boost and Flyback models. The bidirectional converter, with a primary emphasis on stability and efficiency, demonstrates its capability to manage energy flow between solar panels, wind generators, and the grid. The introduced Perturb and Observe (P&O) and Particle Swarm Optimization (PSO) MPPT control methods are compared, with the latter proving to be more effective in minimizing voltage and current ripples. The PSO-MPPT-controlled bidirectional converter exhibits a remarkable efficiency of 97.4%, showcasing its superiority over traditional P&O MPPT and systems without MPPT.
