Robust AGC in a competitive environment

Bevrani, Hassan, Mitani, Yasunori, & Tsuji, Kiichiro (2004) Robust AGC in a competitive environment. In 39th Universities Power Engineering Conference-UPEC 2004, 6-8 Sept. 2004, UK.


A decentralized robust approach is proposed for an automatic generation control (AGC) system based on a generalized AGC structure. This work addresses a new strategy to adapt a well-tested classical AGC scheme to the changing environment of power system operation under deregulation. The effect of bilateral contracts is taken into account in each control area dynamical model as a set of new input signals. The PI-based AGC synthesis is formulated via an H/spl infin/ static output control problem and is solved using an iterative linear matrix inequalities (ILMI) algorithm. A three area power system example with possible contract scenarios and wide range of 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.
