Fractional Order PID Control for AGC of Interconnected Power System

控制性能标准(CPS)下的互联电网自动发电控制(AGC)的控制策略已经取得一些进展。分数阶PID的较强的鲁棒性和非线性适应能力的特征已引起研究人员关注。文中研究了将分数阶PID应用于互联电网AGC控制的问题,并且总结了参数λ、μ的整定规律。仿真结果表明,互联电网AGC的分数阶PID控制系统具有鲁棒性强和非线性适应能力好的优点,并且在CPS指标考核上也比传统PID控制器强。

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 （proportional- integral-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.
