In this study, a fractional-order sliding mode controller is effectively proposed to stabilize a nonlinear power system in a fixed time. State trajectories of a nonlinear power system show nonlinear behaviors on the angle and frequency of the generator, phase angle, and magnitude of the load voltage, which would seriously affect the safe and stable operation of the power grid. Therefore, fractional calculus is applied to design a fractional-order sliding mode controller which can effectively suppress the inherent chattering phenomenon in sliding mode control to make the nonlinear power system converge to the equilibrium point in a fixed time based on the fixed-time stability theory. Compared with the finite-time control method, the convergence time of the proposed fixed-time fractional-order sliding mode controller is not dependent on the initial conditions and can be exactly evaluated, thus overcoming the shortcomings of the finite-time control method. Finally, superior performances of the fractional-order sliding mode controller are effectively verified by comparing with the existing finite-time control methods and integral order sliding mode control through numerical simulations.

Abstract Commissioned for wind power system there are two main types of generators, one is doubly fed induction generator(DFIG), the other is permanent magnetic synchronous generator(PMSG). Compared to DFIG unit, PMSG wind power system is more economical for manufacturing and maintenance. With the higher penetration rate of wind power generation in the grid, the need for the renewable power units to provide active frequency support yields relevant control characteristics in their power converters, for which the visual synchronous generator control exhibits promising features. This paper proposes a visual synchronous technology based PMSG wind power system. The simulation results verified the effectiveness of this proposed controller.
