The objective of the Load Frequency Control (LFC) is to maintain the frequency and to keep tie-line power flows within pre-specified values. In this paper a new systematic approach to design of sequential decentralized load frequency controllers for multi-area power systems based on µ-synthesis is described. System uncertainties according to load, practical constraint on control action and desired performance are included in the synthesis procedure. At each design step, the information about controllers design in the previous steps are taken into account; therefore the method can be less conservative than independent decentralized design and more practical than proposed simultaneous decentralized load frequency controllers. The robust performance in terms of the structured singular value is used as a measure of control performance. A three area power system example is presented demonstrating the controllers’ synthesis procedure and advantages of this method.

Impact and interest:

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.
