Fractional Order PID Control for AGC of Interconnected Power System

The automatic generation control(AGC)of an interconnected power system,based on the NERC's control performance standard(CPS),has made some forward.It has raised concerns that fractional order PID(proportionalintegral-derivative)controller is robust and suitable for the nonlinear systems.This paper studies how to use fractional order PID controller in the AGC of an interconnected power system and sums the parameter setting rules about λ and μ.The results of simulation show that in an AGC system,the fractional order PID controller is also robust,suitable for the nonlinear systems and more suitable for CPS assessment than the classical PID controller.
