Nonlinear control for an optimized grid connection system of renewable energy resources

This paper proposes an integral backstepping based nonlinear control strategy for a grid connected wind-photovoltaic hybrid system. The proposed aims at extracting the maximum power available while respecting connection standards. system has reduced number of electronic converters, thereby ensuring lower costs and energy losses, which improves profitability efficiency effectiveness topology methodology is validated using MATLAB/Simulink software environment. satisfactory results achieved under various atmospheric conditions in different operating modes system, confirm high strategy.
