Abstract

This paper presents a new approach to Load Frequency Control (LFC) for a hydro-power plant. The control algorithm combines sliding mode control with H_∞ technique. The dynamic model of an entire hydro-power plant has been developed. The sliding hyperplane is constructed by H_∞ full state feedback control method. The ideal lossless turbine-penstock model is used in this paper to conduct the simulation. Results are compared with those from traditional PI and LQR designs. It is demonstrated that the proposed sliding mode control blended with H_∞ method improves the system performance under a load disturbance and parametric uncertainties.
