多区域互联电力系统负荷频率的分散控制

THE DECENTRALIZED LOAD FREGUENCY CONTROL FOR MULTI-AREA POWER SYSTEMS

通过引入实时可测量,给出了一种多区域互联电力系统负荷频率控制的动态解耦模型。在大系统关联预估法的基础上,导出了一种仅需本区域的状态信息和在该区域内可测信息的实用有效的分散控制方法。通过实例计算和动态数字仿真,表明用该法设计的分散控制系统,在提高系统的稳定性和动态品质方面,其效果与集中最优控制系统几乎一致。

A decoupled load-frequency control model of a multi-area interconnecting power system is presented and a practical and effective decentralized control method is developed, which needs only its own state information and the information measured in it. It can also improve the stability and dynamic characters of the system. The dynamic simulation of the numerical example of a three-area interconnecting system with this controller showes the dynamic characters are almost the same as the centralized full state feedback optimal control.
