PI-based multi-objective load-frequency control in a restructured power system

Bevrani, Hassan, Mitani, Yasunori, & Tsuji, Kiichiro (2004) PI-based multi-objective load-frequency control in a restructured power system. In SICE 2004 Annual Conference, 4-6 August 2004, Japan.


This paper addresses a new decentralized robust LFC design in a deregulated power system under bilateral-based policy scheme. The LFC problem is formulated to a PI based multi-objective control problem via a mixed H2/Hinf control technique. The robust PI control problem is reduced to a static output feedback control synthesis, and it is solved using a developed iterative linear matrix inequalities algorithm to get a robust performance index close to specified optimal one. The proposed method is applied to a 3-control area power system with possible contract scenarios and a wide range of load changes. The results are compared with H2/Hinf dynamic control design.

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.
