Technical Committee 57 POWER SYSTEMS MANAGEMENT AND ASSOCIATED INFORMATION EXCHANGE

This technical committee explores CIM to XML data exchange for transmission market EDI, with EDF prototypes supporting the methodology. Learn about IEC-ENTSO harmonization, European market standards, and the benefits of standardization for IT cost reduction. Discover the methodological framework and examples, as well as the importance of harmonized business processes and market interfaces. Explore how the CIM Market Extensions and role models enhance IEC standards for a unified European market approach.

  2. TC 57 – WG16Cim Market Extensions for EUCIM and ENTSO-E Market EDI harmonizationFor transmission market EDIleveraging a Common approach for derivating CIM into XML exchanged dataEDF prototypes to support it. Cyril Effantin EDF R&D cyril.effantin@edf.fr

  3. Agenda • Introduction • Aims of the IEC ENTSO-E Market EDI standards harmonization • Methodological framework • Short methodology examples • EDF Prototypes to support the methodology • Conclusion

  4. ENTSO-E (European Network of Transmission System Operators for Electricityhttp://www.entsoe.eu/) • Harmonization Works started in 2005 within IEC-ETSO collaboration (European Transmission System Operators) • from July 2009, ETSO is now fully merged into ENTSO-E ENTSO-E: 42 TSOs from 34 countries ~ 500 million citizen served • 650 GW Generation • 230 000 km EHV-HV lines • 1 500 000 km MV/LV lines Demand: 3 000 TWh/year Exchanges: 300 TWh/year Investments by 2030 for T&D: ~500G€

  5. Strategic targets • Market unbundling has distributed Business Processes across various Energy Stakeholders, typically : • Scheduling • Capacity allocation and nomination • Reserve management • Customer switching • Settlement Calculations… • This however requires coordination of standards across stakeholders • Standardisation is a key element for IT Total Cost of Ownership reduction through : • Harmonization of business processes • Improved component reusability • Market Interfaces • Reduced integration costs

  6. Aims of IEC - ENTSO-E Market EDIstandards harmonization • CIM Market Extension CME creation • Mainly north American vision of the market in 2003 • Taking into account European market design : OTC Over the counter market not modelled • Harmonization benefits • Integrating the European market standard defined by ENTSO-E Market EDI works into IEC • Harmonized European role model • Enhance IEC standards with business processes • Many business processes already modelled by ENTSO-E • Extensive business exchanged messages • Reuse of the ENTSO-E implementation guides • Building of a working framework based on UN/Cefact specification • Hosting the European profile as IEC international standards • Taking advantage of the standardization community

  12. ex: ENTSO-E Scheduling Process Common Methodological frameworkbased on UN/Cefact CCTS UN/Cefact (United Nations/Centre for Trade Facilitation and Electronic Business) CCTS (Core Component Technical Specification) • CCTS Gives a working framework to enhance semantic, interoperability in electronic data exchanges • In particular, it helps to link business processes data exchanges with a common global information model (such as the CIM model)

  13. 3 2 4 Contextual Model or Business Information Entity ( Profiles ) (Sub-Set, Constraints, restrictions) Message Conceptual Model or Message Assembly (Exchanged at app interfaces) Information Model or Core Components ( CIM ) 1 Exchanged Data analysis 5 Implementation Message Model ou Syntax Binding CIM extensions Validation Technological derivation XSD, OWL,RDFS, SQL …etc XML Exchanged Data OMS Common methodological framework inspired from UN/Cefact CCTS (Core Component Technical Specification) standard Business Process Study: Ex: outage Management DMS

  22. XML NDR Naming and Design Rules XSD One more complicated ENTSO-E message derived through the methodology

  23. Proposed CIM Extensions • With Scheduling and Capacity Allocation processes studies we have the following new CIM classes : • Process • TimeSeries • BidTimeSeries • Auction • Price • MeasurementPoint

  24. Proposed CIM Extensions inside IEC62325 package

  25. CIM Issues about combined shared CIM packages

  26. EDF Prototypes to support the modelling methodology • Choice to develop EA’s addins • Addressing the following features : • CIMValidator : • validation of UML Profiles, contextual models and UML message assembly • BasedOn Traceability builder between the stack of UML models • CIMSync : Synchronize UML Models (profiles, contextual, assembly) with the CIM when an CIM evolution is made. • ENTSO-e XSD Builder : production of XSD models from UML Message assembly compliant with ENTSO-e.

  33. Feedback on the common methodological approach • Un/Cefact based methodology facilitated the CIM ENTSO-E Market EDI harmonization. • Having a whole information model giving the next step for future European work, EDI harmonization. • The methodological frameworkreduced the number of added new classes into the CIM to cover all ENTSO-e market exchanged messages through their business processes. • Supporting the methodology with prototypes gives a real proof of concept.
