STS Enhancements
• Initial concepts
• Market requirements
• International standardization
• Enhanced functionality
• The way forward
Overview
• Working group constituted (August 2002)
• User requirements collated (Feb 2003)
• Concepts formulated (Oct 2003)
• STS Standardization commenced (2004)
• STS Enhancement reformatting (Nov 2005)
Historical roadmap
• Backward compatibility• Existing one-way token transfers
• Unit credit transfer
• Meter specific management tokens
• Numeric & Magnetic card token technologies
User requirements
• Bulk data transfers• Meter configuration tables• Tariff tables• Feedback information• Consumption feedback data
User requirements
• Meter feedback data• Meter capability
• Default consumption feedback
• Specific detailed information
• Meter status
• Customer profile information
User requirements
• Dual key management
User requirements
• Facilitates zoning
• Simplifies field maintenance
• Assists management
• Token carriers• Numeric
• Magnetic card
• Dallas iButtons
• Smartcards
• Wireless / PLC carrier technologies
User requirements
• Adoption of a Virtual Meter Model
• Separation of STS Enhancement Standard and Companion specifications
• Translation and acceptance of STS into an IEC format
• Implications for vending (POS), key management, meter, and meter certification
Format standardization
Virtual meter model
STS reference model
• Service types supported:• Electricity (currency and units)
• Water (currency and units)
• Gas (currency and units)
• Connection time (currency and units)
• Heat (currency only)
Enhanced functionality
• Functionality enhancements• In-line water meters
• End-of-line water meters
• Energy / water balancing
• Maximum demand meters
• Time of use meters
• Line quality information
• Load control
Enhanced functionality
• Encryption algorithms• STA• Single DES• Triple DES
• Key management• Existing key management centre• Secure module upgrades• Key management centre upgrade
Enhanced functionality
• Introduction of the UML format• Finalisation of meter objects• Definition of meter object processes• Detailing the extensions to
IEC62055-41, IEC 62055-51• Submission to the STS Association
board by December 2006
The way forward
