Application of Kharitonov's Theorem and its Results to Load Frequency Control
Bevrani, Hassan (1998) Application of Kharitonov's Theorem and its Results to Load Frequency Control. Iranian Journal of Electrical Science and Technology (BARGH), pp. 82-95.
The classical design of load-frequency controller is usually based on the conventionally tuned PI controllers. These controllers are designed for a particular operating point of the system. Closed-loop system stability and acceptable performance is only achieved for slight deviations from the nominal operating point of the power system. In the present paper, to overcome the problem of parameter variations and to maintain the simplicity of controller, a new robust power system load-frequency controller is proposed. The Kharitonov’s theorem and its results are utilized to design robust controller to achieve robust stability and performance. Then, robust stability analysis is carried out graphically by employing the notions of "Value set" and "Zero exclusion". Simulation results are given to show the robust stability and performance of the designed controller over a wide range of system uncertainties and load disturbances.

Citation countsare sourced monthly fromand 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.
