Load-frequency regulation under a bilateral LFC scheme using flexible neural networks

Bevrani, Hassan, Hiyama, Takashi, Mitani, Yasunori, Tsuji, Kiichiro, & Teshnehlab, Mohammad (2006) Load-frequency regulation under a bilateral LFC scheme using flexible neural networks. Engineering Intelligent Systems, 14(2), pp. 109-117.


A new approach based on artificial Flexible Neural Networks (FNNs) is proposed to design of load frequency controller for a large scale power system in a deregulated environment. In this approach, the power system is considered as a collection of separate control areas under the bilateral Load Frequency Control (LFC) scheme. Each control area which is introduced by one or more distribution companies, can buy electric power from some generation companies to supply the area-load. The control area is responsible to perform its own LFC by buying enough power from pre-specified generation companies, which equipped with a FNNs based load frequency controller. The proposed control strategy is applied to a 3-control area power system. The resulting controllers are shown to minimize the effect of disturbances and achieve acceptable frequency regulation in the presence of load variations and line disturbances.

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.
