WG D 2. 24

Industry Coordination WG D 2. 24 sets the vision and requirements, not the standards Objectives o o Standard Committees/Initiatives Align with current and emerging standards, and leverage work done Produce a complete and consistent specification of the architecture Coordination with o o IEC TC-57 related working groups (mainly CIM) North American ISO/RTO Council EAS Project

WG D 2. 24 1. IEC-CIGRE Relationships Liaison type A between CIGRE D 2 and IEC TC 57 IEC Category A liaison for Organizations that make an effective contribution to the work of the Technical Committee for questions dealt with by this TC. Such organizations can exchange all relevant documentation and are invited to meetings. They may nominate experts to participate in a WG. 2. Mo. U to clarify organization & management General management: CIGRE: D 2. convenor => A. Steven IEC: TC 57 chairman => T. Lefebvre Operational management: CIGRE: S. Neuman (CIGRE member, TC 57 member) IEC: P. Skare (CIGRE member, TC 57 -WG 19 chairman) Members: Most of D 2. 24 members are TC 57 members

WG D 2. 24 In brief The ultimate goal of WG D 2. 24 is to deliver a complete specification for the next EMS/MMS architecture This specification will become a key building block for future EMS/MMS procurements WG D 2. 24 will work closely with the vendors to develop requirements and a time-based prioritized roadmap, which is technically and commercially viable WG D 2. 24 intends to leverage existing IEC TC-57 Standards. Conversely, new IEC TC-57 standardization efforts may emerge from the WG D 2. 24 work products
