1 Cigre WG D2.24 EMS Architectures of the 21st Century
Vasteras 2008 Cigre WG D2.24 EMS Architectures of the 21st Century Alain P. STEVEN PJM Interconnection, LLC, USA CIGRE WG D2.24 Convenor Jay BRITTON AREVA T&D, USA TC57, CIM expert Thierry LEFEBVRE RTE, France TC57 chairman

2 Outline Part 1: Part 2 : (Thierry Lefebvre) (Jay Britton)
Overview, goals Relationships with IEC-TC57 (Thierry Lefebvre) Part 2 : CIM in CIGRE D2.24 Focus on the « Information Architecture » (Jay Britton)

3 Several organizations sharing the same goal
Cigré International Council on Large Electric Systems Facilitates, develops and synthesizes technical knowledge in all the fields related to HV generation and transmission Based in Paris, 80 member countries VLPGO Very Large Power Grid Operators International initiative regrouping the world’s twelve largest grid operators Focus is on addressing challenges unique to the operation of very large power grids (> 50,000 MW) IEC International Electrotechnical Commission Prepares and publishes International Standards for all electrical, electronic and related technologies IRC/ITC IRC = North American ISO/RTO Council (CEO level) ITC = Information Technology Committee, reports to IRC (CIO level)

4 (Cont’d) 10/03: First meeting of the VLPGO
CEO level Creation of WG #2 - EMS Architectures of the 21st Century 01/06: IRC/ITC launches EAS project EAS = Enterprise Architecture Standardization Complementary to the work of WG #2 01/07: VLPGO WG #2 becomes Cigré WG D2.24 Expands membership to the rest of the industry Formalizes the work of WG #2 and provides a formal communication channel with IEC 06/07: EAS project merges with Cigré WG D2.24 Provides a consistent description of the architecture, from the high level requirements down to the detailed message definitions

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

10 Core Business Processes
Common User Interface Operate the Grid - Monitor Operations - Forecast demand - Schedule supply - Control generation - Control transmission Operate the Market - Develop real-time markets - Develop day-ahead markets - Settle the market - Monitor the market Plan the Assets - Determine capacity adequacy - Approve generation citing - Plan transmission expansion - Plan generation capacity Orchestration Engine and Work Flow Optimization engines MIPS engine PRA Clearing engine IAP SE DPF Event correlation Rules LMP calc Lagrangian Substation SCADA Event processing Data acquisition FTR Engine Auction clearing Pattern recognition Intelligent agents ARR engine Visualization Business Services Technical Services Operating system services Database services High-availability services Portal Platform monitoring services User interface components Historical logging components Standard data model [CIM] Rules engine components DW/ODS Security services Application monitoring services Logging services Time management services Diagnostics services High-speed integration services Enterprise integration services Data access services Exception management services Model maintenance services Common name service Data synchronization services Failover/ redundancy services Repository services

14 Seven Layers for a reference architecture
Application and Integration Architecture Information Architecture Security Architecture Platform Architecture Network Architecture Business Continuity Architecture User Interface Architecture

15 Harmonization Process
RTO/ISO (IRC) IT Council Cigre SC D2 VLPGO WG 24 RTO/ISO EAS Project New Members VLPGO WG-2

16 Task Forces & Deliverables
Cigre WG D2.24 Task Forces & Deliverables Detailed Services and Messages Definitions (EAS/TF 5) High Level Architecture Requirements and Applicable Standards (07/08) CRD TF 1/2 Defines Application Modularity and Granularity (07/08) Generic Business Processes (TF 3a) High Level Services Definitions and Interfaces (12/08) Standard Business Services (TF 3b) Standard Technology Services (TF 4)


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
