Abstract

Frequency control is one of the important control problems in interconnected power system design and operation, and is becoming more significant today due to the increasing size, changing structure, emerging microgrids, renewable energy sources, environmental constraints, and new uncertainties. In a conventional power system, the majority of supply-demand balancing is achieved by controlling the output of dispatchable generation resources rather than distributed generators (DGs) and renewable energy sources (RESs) to follow the changes in demand. The frequency control in a modern power system should handle complex multi-objective regulation optimization problems characterized by a high degree of diversification in policies, control strategies, and widely distribution in demand and supply sources. At present, the power system utilities participate in the frequency regulation task with simple and classical tuned controllers. Most of the parameters adjustments are usually made in the field using heuristic procedures. Existing frequency control parameters are usually tuned based on experiences, classical methods, and trial and error approaches, and they are incapable of providing optimal dynamical performance over a wide range of operating conditions and various load scenarios. This seminar provides a thorough understanding of the fundamentals of frequency control in modern power systems as well as in the Microgrids with distributed DGs/RESs; and addresses some robust synthesis schemes. The seminar mainly summarizes the research and academic experiences of the speaker on the related fields in three countries of Iran, Japan and Australia.
