Backstepping Controller Design for Maximum Power Harvesting from Solar-Wind Hybrid Energy Conversion System

Renewable energy sources are essential in the battle against escalating dangers associated with climate change and global warming. Among these resources, wind and solar energy are readily available and frequently used. An effective approach to harnessing these sources involves integrating a wind energy conversion system (WECS) and a solar energy conversion system (SECS) and utilizing the combined output to supply the grid. This paper presents a backstepping controller to maximize the power transfer from this hybrid system to the grid. The proposed controller enables the fast realization of the maximum power point (MPP), resulting in grid-side total harmonic distortion (THD) below 5%. The results are simulated in MATLAB/Simulink to demonstrate the system's effectiveness.
