Recently eco-friendly solutions are gaining attraction for energy generation to overcome the environmental problems, but unpredictable nature and high dependency on weather state are the main restriction of renewable sources. To overthrown this drawbacks, various renewable sources need to be integrated such us PV, wind turbines and battery, the biggest challenge of this integration is to control and manage the power flow. In this paper a control method is proposed to deal with the power flow from a standalone PV-wind-battery to meet the load demand. The system is validated in the Matlab/Simulink environment and the simulation results obtained confirm the effectiveness of the proposed control. Streszczenie. Ostatnio ekologiczne rozwiązania zyskują na atrakcyjności dla wytwarzania energii ale nieprzewidywalny charakter i wysoka zależność od stanu pogody są głównymi ograniczeniami źródeł odnawialnych. Aby usunąć te wady, należy zintegrować różne źródła odnawialne, takie jak PV, turbiny wiatrowe i baterie. Największym wyzwaniem związanym z tą integracją jest kontrolowanie przepływu energii i zarządzanie nim. W niniejszej pracy zaproponowano metodę sterowania, aby poradzić sobie z przepływem mocy z autonomicznej baterii wiatrowej PV i aby sprostać wymaganiom obciążenia. System jest walidowany w środowisku Matlab / Simulink, a uzyskane wyniki symulacji potwierdzają skuteczność proponowanej kontroli. Sterowanie i zarządzanie mocą w hybrydowych sysytemach wytwarzania energii

<span>Wind turbines components work as nonlinear systems where electromechanical parameters change frequently [1], which makes nonlinear control an interesting solution to prevail good efficiency. SMC has been largely used in electrical power applications because it offers interesting features like robustness to parametric uncertainties and external disturbances, to conquer the biggest drawback of the SMC, adaptation strategy consists on updating the sliding gain and the turbine torque to contribute with some important characteristics such as chatter-free performance, heftiness, robustness and secure power system operation. Matlab tests are introduced and compared.</span>

In this paper, a robust nonlinear controller based on sliding mode control strategy is adopted for a variable-speed wind energy conversion system with a double-fed asynchronous generator (DFIG). Firstly, field-oriented control law based on PI controllers has been introduced. However, wind turbines components work as nonlinear systems where electromechanical parameters change considerably; thus, a SOSMC with a simple function to smooth control signals is introduced, the aim of the proposed controller is to contributes with some important features such as power fineness, minimize the chattering, ameliorate respond time and deal with grid requirements. Matlab tests are introduced in an attempt to confirm the effectiveness of the proposed control.
