Reduced µ-based load frequency controller in a deregulated power system environment

Bevrani, Hassan (1999) Reduced µ-based load frequency controller in a deregulated power system environment. In 14th International Power System Conference (PSC), 1999, Tehran, Iran.


Power systems are in transition from large, vertically integrated utilities providing power at regulated rates to restructured systems with competitive companies selling unbundled power at lower rates. In new environment, a power system includes separate generation, transmission and distribution companies with an open access policy. The classical control methodologies do not satisfy new objectives and novel control strategies are needed to maintain system reliability and meet new demands. This paper presents a reduced-order robust load-frequency controller for a restructured power system using singular values theorem. The singular values of the system observability matrix of the high order µ-controller are analyzed, and a method is used to achieve a low order load-frequency controller without degradation of the closed loop system performance. The proposed technique is tested on a power system using computer simulation.

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.
