A new design approach to load frequency control tuning

This paper presents a new robust technique for tuning the parameters of a state feedback controller for load frequency control (LFC) of interconnected power systems using sequential quadratic programming (SQP) method. In this method the frequency deviation of the system is directly utilized to tune the controller parameters. The simulation studies are carried out for two-area interconnected power system. The Comparative results of the proposed method and a conventional PI controller show its robustness with a satisfactory response when the parameters of the system change.
