Improved frequency response of a wind-diesel power system with adaptive RBF sliding mode control of SMES

In this paper, improved frequency response of a wind-diesel power system is reported with the adaptive RBF-based sliding mode control of SMES. With the converter interface, a fast-acting and high power density device i.e SMES is interconnected with the system to carry the required power exchange. On the basis of switching manifold design and adaptive RBF neural network, a sliding mode controller is developed to control the firing angles of the converter, and hence the effective operation of SMES is achieved. MATLAB simulations are carried out and are presented to show the improved frequency response whenever any disturbance in load, disconnection of wind power or wind power disturbance occurs in the system
