ABSTRACT
This chapter deals with frequency control of power systems with synchronous generators as the main components. For any control problem, the design procedure consists of understanding of the control objectives, figuring out the plant model, the inputs and outputs of the controller, the controller design, and finally validation of the controller's performance. The chapter presents the plant model, starting from Newton's second law for a rotating mass to derive the swing equation for a synchronous generator. It discusses the first control objective, steady-state frequency deviation reduction, and the design methods. The chapter also presents the second control objective, steady-state frequency deviation elimination, and the design methods. It describes Automatic generation control, and then presents validation results using time-domain simulation. The chapter provides more examples related to frequency control analysis, and illustrates MATLAB codes to help readers improve their skills of conducting linear system analysis.
