Research of EMS architecture based on wide-area information

Along with the development of the modern information technology, a lot of wide-area information such as WAMS (Wide-Area Measurement System) information, need to access to the energy management system (EMS). But all the present EMS system architectures are designed in a tight coupling way which is inflexible and closed. This causes these systems hardly to benefit from this information. A new EMS system design solution is presented in this paper. By means of the research to the Service-Oriented Architecture (SOA) and other technologies such as the Common Object Request Broker Architecture (CORBA), the Rich Internet Application (RIA), as well as the IEC61970 standard, this solution provides a scalable and reusable system architecture for the future energy management system. This architecture will become the foundation of the next generation EMS system, and will bring a bigger benefit to the electric power enterprises.
