Generalized Design of a Physically Referenced Feed-Forward and State Feedback Controller for Load Frequency Control

In this paper, a generalized Physically referenced Feed-forward State Feedback Controller (PFSFC) for the Load Frequency Control (LFC) system is proposed considering a state feedback controller and a feed forward gain. We have presented a procedure to find a range of controller values for stable operation of the system while maintaining the desired frequency. These wide range of controller variations will give flexibility to the operator to choose a set of controller values according to the need of the load demand from the power system. The effectiveness of the proposed method is presented through a set of results considering standard models from the existing literature. A comparative study with a set of existing works is also presented to demonstrate the applicability and usefulness of the proposed method.
