Decentralized robust load-frequency control: A PI-based approach
Bevrani, Hassan, Mitani, Yasunori, & Tsuji, Kiichiro (2004) Decentralized robust load-frequency control: A PI-based approach. In International Conference on Electrical Engineering (ICEE) 2004, 2004, Sapporo, Japan.
This paper addresses a robust control method to decentralized PI-based load-frequency control (LFC) synthesis in a multi-area power system. The LFC problem is reduced to a static output feedback H∞ control problem and then it is solved using a developed iterative linear matrix inequalities (ILMI) algorithm to get an optimal performance index. A three control area power system example with a wide range of load changes is given to illustrate the proposed approach. The obtained controllers are compared with full dynamic H∞ controllers. The results show the proposed controllers guarantee the robust performance for a wide range of operating conditions as well as full-dynamic H∞ controllers.
Impact and interest:
Citation counts are sourced monthly from and 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.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
Full-text downloads displays the total number of times this work’s files (e.g., a PDF) have been downloaded from QUT ePrints as well as the number of downloads in the previous 365 days. The count includes downloads for all files if a work has more than one.
