Robust Decentralized LFC Design In a Deregulated Environment

Bevrani, Hassan, Mitani, Yasunori, & Tsuji, Kiichiro (2004) Robust Decentralized LFC Design In a Deregulated Environment. In 2004 IEEE International Conference on Electric Utility Deregulation, Restructuring and Power Technologies, 2004. (DRPT 2004), April 2004, Hong Kong.


In this paper, a decentralized robust approach is proposed for load-frequency control (LFC) design in a deregulated environment using bilateral market scheme. First, the effect of bilateral contracts as a set of new input signals is taken into account in the control area dynamical model, and then the LFC problem will be formulated as a multi-objective problem to cover robust performance,practical constraint on control action and minimize the effects of load disturbance under wide range of demand changes. A mixed H2/Hinf is used to solve the problem and design the desired robust controllers. A three control areas power system example with possible contract scenarios and load changes is given to illustrate the proposed approach. The resulting controllers are shown to minimize the effect of disturbances and maintain the robust performance.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
