Research On Multi-Agent Communication Of EMS-Oriented Based On SOAP

With the development of electric power market, the centralized legacy energy management system (EMS) is hardly adaptive to the polytrope of market environment increasingly. Based on the theory of multi-agent system (MAS) and ontology, and considered IEC 61970 common information model (CIM) as the data ontology of EMS region, the structure of ontology for EMS is established. And concerned with the function and application of EMS, a new and open type of EMS-oriented multi-agent architecture is presented. Furthermore, the simple object access protocol (SOAP) in prevalent technology of Web Service is adopted to transmit data among agents, and the multi-agent communication mechanism is designed. Lastly the presented mechanism is actualized on the platform of J2EE. This architecture can meet the ever-increasing requirements of reliability and interoperability for EMS of new generation, and be suitable for the trend of information interaction in power system via Internet.
