On the other hand multi-agent systems are attracting growing interest for different applications of power engineering. This paper presents the possibility that IEC61850 could be applied to build intelligent agents for power engineering applications. The paper investigates the correlation between IEC61850 and multi-agents and presents IEC61850 service tracking as a scenario. First, briefly introduces reporting and service tracking;then, investigates agents, intelligent agents and the characteristics of intelligent agents;last, analyzes the characteristics of service tracking and compares it with intelligent agents. And analysis shows that IEC61850 could be applied to build intelligent agents, which represents a significant step forward for MAS to apply in power engineering.展开更多
