5. Mission & Scope Mission Scope
Develop the vision for the architecture of the next generation of Energy Management and Market Management Systems,
Gain broad adoption by the industry
Facilitate its implementation as a de facto standard
Scope
Real-time Systems associated with the transmission and market operations
Extendable to generation and distribution

6. Goals and Objectives
Goal: to develop the vision for a highly interoperable and reusable architecture, and to facilitate its implementation through a common coordinated procurement process
Objectives
Develop a common set of requirements
Develop a description of the architecture and its standard components
Facilitate its implementation and its funding through a coordinated procurement process along with a roadmap agreed upon between end users and manufacturers

8. WG-2 Initial Findings Common Issues Perceived Root Causes
High development and maintenance/support costs
Lack of modularity and interoperability among multiple vendors
Limited innovation
Limited number of viable vendors
Inadequate security
Multiplicity of user interfaces
Perceived Root Causes
Limited standardization (Market requirements as well as vendor products)
Limited market(s) size
Real-time performance imperatives
High investment in legacy products
Limited software reuseability

9. Design Principles
Component based, Services Oriented Architecture for integration and reusability within the Enterprise
Modularity based on businesses processes componentization
High Speed Bus for real-time message exchange
Common Information Model for data standards
Security layer
Built on industry standards
Common User Interface
Common Modeling tools integrating display and data maintenance
Transportable to future technologies
Scalable

18. Industry Coordination Standard Committees/Initiatives
WG D2.24 sets the vision and requirements, not the standards
Objectives
Align with current and emerging standards, and leverage work done
Produce a complete and consistent specification of the architecture
Coordination with
IEC TC-57 related working groups (mainly CIM)
North American ISO/RTO Council EAS Project

19. IEC-CIGRE Relationships
Liaison type A between CIGRE D2 and IEC TC57 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.
MoU to clarify organization & management
General management:
CIGRE: D2.convenor => A. Steven
IEC: TC57 chairman => T. Lefebvre
Operational management:
CIGRE: S. Neuman (CIGRE member, TC57 member)
IEC: P. Skare (CIGRE member, TC57-WG19 chairman)
Members:
Most of D2.24 members are TC57 members

20. In brief
The ultimate goal of WG D2.24 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 D2.24 will work closely with the vendors to develop requirements and a time-based prioritized roadmap, which is technically and commercially viable
WG D2.24 intends to leverage existing IEC TC-57 Standards. Conversely, new IEC TC-57 standardization efforts may emerge from the WG D2.24 work products
