Estimation and Prediction in Load-frequency Control
Many controllers designed for load-frequency control (LFC) in power system are based on the knowledge of system state, which is generally not measured. This paper presents a method for estimation of disturbance and system state in LFC. In power systems, measurement signals and control signals are transmitted over long distances between controller and power units what introduces large time delays in the system. Therefore, a state prediction method to overcome the effects of the time delay is presented here. A power system consisting of three interconnected areas represented by thermal power units is simulated. Simulation results of state and disturbance estimation and also state prediction are shown here.
