电池储能系统与发电机励磁的多指标非线性协调控制

摘要

A multi-index nonlinear coordinated control scheme for single machine infinite bus power system with battery energy storage system (BESS) is proposed. The outstanding feature of the BESS is its ability to provide fast and effective control of both active and reactive power which makes BESS superior compared with other flexible alternating current transmission system (FACTS) devices. The design process shows that the multi-index nonlinear control design method can effectively solve the control problems of high order MIMO nonlinear control systems. The simulation results show that this control design method is effective for improving the dynamic characteristics of the state variables and enhancing the stability of the system.This project is supported by National Natural Science Foundation of China (No. 60674035).%采用多指标非线性控制方法对电池储能系统(Battery Energy Storage System,BESS)与汽轮发电机的励磁进行协调控制设计.相比于其他的灵活交流输电系统(Flexible Alternating Current Transmi ssion System,FACTS)器件,BESS的优点在于能够同时对电力系统的有功和无功功率进行快速且有效的控制.设计表明采用多指标非线性控制设计方法能很好地解决高维MIM0非线性系统的控制设计问题.仿真结果表明所设计的控制规律能明显地改善系统各状态量的动态特性,并有效地提高系统的稳定运行能力.
