基于多Agent 优化协调的电力系统二级电压控制

在多Agent的二级电压控制系统基本原理的基础上,将多Agent系统的相关技术引入无功电压快速协调控制,探讨了在电力系统紧急情况下,基于多Agent的二级电压控制系统的协调和协作方法以及优化控制策略.通过引入虚拟控制Agent分组的概念,将多Agent系统中常用的合同网协议应用于二级电压控制的多Agent协调,改善了紧急状态下系统的电压调控能力.以装有多个静态无功补偿器的新英格兰系统为例进行数字仿真研究,验证了控制策略的有效性和灵活性.

Optimal Coordination for Multi-agent Based Secondary Voltage Control in Power Systems

Within the framework of the multi-agent based secondary voltage control system,the communication methods,collaboration protocol and optimal control strategy are investigated for enhancing the ability of fast and coordinated voltage control in power system.The performance in system contingencies is mainly discussed.The concept of virtual control agency is proposed to adapt the emergent dynamic control environment.Contract net protocol,which is widely used in coordination of multi-agent system(MAS),is introduced to realize optimal coordination and cooperation among control agents.The simulation results of the classic New England system equipped with several static var compensators(SVC) show the effectiveness and flexibility of the control scheme.
