Robust LFC design using mixed H2/Hinf technique

Bevrani, Hassan, Mitani, Yasunori, & Tsuji, Kiichiro (2004) Robust LFC design using mixed H2/Hinf technique. In International Conference on Electrical Engineering (ICEE) 2004, 2004, Sapporo, Japan.


This paper addresses a new decentralized robust control design for load-frequency control (LFC) in multi-area power systems. The LFC problem is considered as a multi-objective problem and formulated via a mixed H2/H∞ control technique, then it is easily carried out to synthesis the desired robust controllers by solving standard linear matrix nequalities (LMI). A three-area power system example with a wide range of load changes is given to illustrate the proposed approach. The results are compared with pure H∞ method. It is shown that the designed controllers maintain the robust performance, minimize the effect of disturbances and specified uncertainties, effectively.

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.
