Abstract
In this paper, a decentralized controller for the load frequency control (LFC) problem in power systems is designed based on a robust H∞ control technique formulated as a Linear Matrix Inequalities (LMI) problem. To achieve decentralization, interfaces between interconnected power system\´s control areas are treated as disturbances. The LMI control toolbox is used to solve such a constrained optimization problem for LFC applications. The robust performance of the proposed controller is illustrated and compared with that of a conventional controller through simulation of a two-area power system with a variety of disturbances. Results show that H∞ control technique via the LMI approach is an ideal tool for decentralized load frequency control design.
