多Agent系统在区间振荡控制中的应用

Application of Multi-Agent System in Control of Inter-Area Oscillation

针对目前区间振荡控制模式中存在的集中控制和广域电力系统延时等问题,在对现有的广域网内区间振荡控制系统和多Agent系统研究的基础之上,提出了基于相角测量单元和多Agent系统的区间振荡控制协作模型。论述了该模型内各Agent的主要功能,设计了基于该模型的3级电力系统稳定器信号的监控策略,并给出了该模型抑制区间振荡的协作过程。数字仿真验证了基于多Agent系统构建区间振荡控制系统的可行性和有效性。

In view of the problems existing in inter-area oscillation control modes such as centralized control and time delay in wide area power system, on the basis of the research on inter-area oscillation control system within wide area and the research on multi-agent system （MAS）, an inter-area collaborative oscillation control model based on phasor measurement units （PMUs） and MAS is proposed. The main functions of all agents in this model are dissertated; the monitoring strategy of signals in the three-level power system stabilizers （PSSs） based on the proposed model is designed; and the collaborative process of suppressing inter-area oscillation by the proposed model is given. Digital simulation results verify the feasibility and effectiveness of constructing an inter-area oscillation control system based on MAS.
