摘要
针对双区域互联电力系统中的负载频率控制(LFC)问题,文中比较了基于模糊逻辑的不同隶属函数的比例积分微分控制器(FPID)。采用蜘蛛猴优化(SMO)算法对控制器参数进行优化,使用再热式燃气轮机系统的线性化模型,结合发电率约束(GRC)和调速器死区(GDB)等非线性因素对研究进行了扩展。实验结果表明,在阶跃负载扰动(SLP)为1%的情况下,SMO算法在峰值欠冲、峰值过冲、稳定时间以及联络线潮流偏差等方面均优于粒子群优化(PSO)和基于"教与学"优化(TLBO)算法。
In order to solve the load frequency control(LFC)of two area interconnected thermoelectric system,the proportion integral differential controller(FPID)is compared based on different membership functions of fuzzy logic.Spider monkey optimization(SMO)algorithm is used to optimize the parameters of the controller,and the linearization model of reheat gas turbine system is used to expand the research with the nonlinear factors such as power generation rate constraint(GRC)and governor dead zone(GDB).Experimental results show that SMO algorithm is superior to PSO and tlbo in peak undershoot,peak overshoot,stability time and tie line power flow deviation when the step load disturbance(SLP)is 1%.
