Update on CIGRE D2.24 initiative

Summary form only given. CIGRE D2.24, EMS architectures for the 21st Century, was created in 2007, but the work was originally started in the very large power grid operators organization. The intention of this group is to define the architecture needed for both energy management systems (EMS) and market management systems (MMS) based on service oriented architectures (SOA). An agreement with the International Electrotechnical Committee (IEC) Technical Committee 57 (TC57) power systems management and associated information exchange exists to incorporate the aspects of this work into the standards of TC57 where applicable. The D2.24 work has embraced the existing TC57 standards, and is basing the new work on such IEC standards as IEC 61970/61968 - the common information model (CIM). The key elements of the D2.24 work include: information architecture; integration architecture, user interface architecture, and security and network architeure. This paper will describe these sections.
