OASIS Standards for smart grids Light, loose integration for inter-domain communications Toby Considine TC9, Inc
Smart grids are meant to save resources through improved awareness and control
Inappropriate focus on process can actually waste resources

SIMPLE INTERFACES LET US OPTIMIZE INTEROPERABLE SERVICES WITHOUT COMMITTING TO FIXED PROCESSES

Interacting with complex objects is hard
Simplified schematic of flatworm nervous system
Process integrations value effort over performance
Process compliance merely defines poor performance
Details are a barrier to interoperation
Interfaces should hide details to enable interoperation
Define business needs, not technical processes.
We use composite protocols and security when we want them to scale.
HTML IMAP / POP3 SMTP TELNET URIs
Coordinate systems using result-oriented semantics
Only coordination that is simple and secure will scale
Building systems are becoming interoperating services
Building-based agents will act as personal day traders in new energy markets
• • • • System agents defend mission Enterprise (or home) defines value Power Grid offers clearing market Building agents choreograph response
Zero net energy buildings will require ever more integration
Energy Purchase Energy Generation Energy Use Energy Storage Energy Recycling Energy Conversion
Power Load Management (TC57) Financial Instruments (ISO20022) Enterprise Scheduling (CalConnect) THREE CIMS FOR INTER-DOMAIN INTERACTION
Energy Interoperation TC
• • • Interactions for DR and DER Distinguishes between Managed and Collaborative energy – Direct load management by the utility or service provider – Economic messages to align interests.
Contributions – OpenADR from Lawrence Berkeley Labs – Business cases from NAESB
Energy Market Information Exchange TC (EMIX)
• Price and Product communication – Price is neither tariffs nor pricing – Energy characteristics of interest to consumer – Volatile products are time dependent
Schedules for the internet of things (WS-Calendar)
• • Calendaring & Scheduling Consortium – IETF RFC 2445, 2446, 2447 – now RFC 5545… – Standard XML serialization Common semantics for interactions in – Enterprise – Energy – Buildings – – Finance (PIMs and Vehicles)
There are many standards, select the right one for the job
