© ABB Power Technologies - 2 Next Steps – Messaging standard Proof of concept demonstration – SCUC messaging Scope Create XML input messages Use a small 100 bus model Create Prototype Adapters for each SCUC ABB, Areva, and Siemens Prototype testing Verify SCUC XML output complies with the schema Documentation for standards promotion Goal Further ‘cleanup’ and tuning of CME schema Demonstrate the feasibility of SCUC as ‘plug and play’

© ABB Power Technologies - 3 Next Steps – Messaging Standard Standards Promotion IEC TC57 WG13 and WG16 At conclusion of Proof of Concept UML and supporting documents Messaging Standard for Additional Applications Market Participant Bid Submission Extensive schema reuse from SCUC messaging Network Applications (e.g. power flow, security analysis, state estimation) Partially accomplished w/ SCUC messaging Settlements Metering
