基于组织的多Agent广域服务的模型研究

The Model Study of Multi-agent Wide Area Service Based on Organization

针对分布式实时控制系统,运用Agent和组织的思想,提出了多Agent广域服务的模型。对多Agent参与的问题空间加以描述,由分布在各处的多个Agent构成组织协同完成联合任务、实现广域服务,阐述Agent组织的分布协调、各级协调、平等自治几种新型控制结构,分析广域服务的组织中Agent的内部结构和行为,研究广域动态决策、信息过滤与主动通讯、通过协同和相互支援提高系统可靠性和容错性、综合反射的分析方法等工作机制和策略。以电力系统广域后备保护为例,分析广域协同保护和支援服务的组织行为,与常规方法比较,扩大了保护范围、缩短了保护响应时间、提高了系统整体可靠性。

The model of multi-agent wide area service based presented,The problem space with multi-agent joining is firstly on organization for distributed real-time control system is described,in which distributed multi-agents are composed to the organization to cooperate and complete the joint task then implement wide area service.Several novel control structures of agent organization are analyzed,such as distributed coordinating,hierarchical coordinating and equal autonomous structure.The architecture and behaviors of the agent in wide area service are expatiated. Some mechanisms and strategies which include wide area dynamic decision-making,information filtering and proactive communication, cooperation and supporting each other to improve the reliability and robustness,and integrated-reflecting software analysis method are given.At last,the electric power system wide area backup protection is studied as an example to analyze the organizational behavior of wide area cooperative protection and supporting service.Compared with traditional methods,new wide area protection based agent organization can expand protection range,shorten response time and improve the reliability of whole system.
