We need to solve the problem due to the nonlinearity and power fluctuation in the photovoltaic (PV) connected storage system and grid; for that, the authors develop an algorithm to obtain the maximum power point tracking (MPPT) via control of the duty cycle of DC/DC boost converter. Consequently, they design an MPPT based on the second-order sliding mode control. Next, generating the law control founded on the Lyapunov theory can augment the robustness and stability of the PV connected grid. Then, they add a battery energy storage system (BESS) with a control management algorithm in the DC/DC side to eliminate any fluctuation of the output power of the PV system because of the temperature and irradiation variation. On the grid side, they control the DC/AC inverter side by the three-phase voltage source inverter control (VSIC) as a charge controller for the grid parameters.

This paper deals with a nonlinear control algorithm based on a sliding mode theory to reach the maximum power point tracking of a variable-speed wind energy conversion system. The proposed method allows us to combine the sliding mode and fractional-order theory. The fractional-order component of the control law is introduced by a sliding surface. In order to validate this controller, fractional and integer sliding modes are developed. The proposed fractional-order sliding mode control law is tested in a Simulink/Matlab environment. The simulation results show the effectiveness of the proposed scheme, suppression of the chattering phenomenon and robustness of the proposed controller compared to the integer sliding mode control law.

In this paper enhanced control strategies for standalone microgrids based on solar photovoltaic systems (SVPAs) and diesel engine driven fixed speed synchronous generators, are presented. Single-phase d-q theory-based sliding mode controller for voltage source converter voltage source converter (VSC) is employed to mitigate harmonics, balance diesel generator (DG) current, and to inject the generated power by SVPA into local grid. To achieve fast dynamic response with zero steady-state error during transition, sliding mode controller for inner control loop is employed. To achieve maximum power point tracking (MPPT) from SVPA without using any MPPT method, a DC-DC buck boost converter supported by battery storage system is controlled using a new control strategy based on sliding mode control with boundary layer. In addition, modeling and detailed stability analysis are performed. The performance of the developed control strategies, are validate by simulation using MATLAB/Simulink and in real-time using hardware prototype.
