Abstract

In this paper, a hybrid load frequency controller for a network with two-area interconnected power system is presented to damp the deviations in frequency and tie line power due to load changes in each time. The system includes DC control interacting with the conventional AC area controls. The stability of the network in these two areas is controlled by a new control method. This method is a Model Reference Adaptive Control method (MRAC) based on the combination of Linear Quadratic Regulator (LQR) control and pole placement that are regulated by a Genetic Algorithm (GA). Digital simulation results are obtained to prove the effectiveness of these hybrid controllers over the load frequency control system. ฉ 2012 IEEE.
