Abstract
This paper presents a new approach for load-frequency control in large scale power systems. The method uses only samples of area control error signals from which it estimates all states and disturbances in the system. Predictor is used to compensate for the time delay in control signal. A novel approach for designing a sliding surface is presented. Simulation results of three-area power system using designed controller are shown
