OASIS Standards for smart grids

• Light, loose integration for inter-domain

2
Smart grids are meant to save resources through
improved awareness and control
3
Inappropriate focus on process can actually waste
resources

• "If something is not worth doing, its not worth
  doing well" - Peter Drucker

4
Simple Interfaces let us optimize interoperable
services without committing to fixed processes

6
Interacting with complex objects is hard
Simplified schematic of flatworm nervous system
7
Process integrations value effort over performance
8
Process compliance merely defines poor performance
9
Details are a barrier to interoperation
10
Interfaces should hide details to enable
interoperation
11
Define business needs, not technical processes.
12
We use composite protocols and security when we
want them to scale.
13
Coordinate systems using result-oriented semantics
14
Only coordination that is simple and secure will
scale
15
Building systems are becoming interoperating
services
16
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

17
Zero net energy buildings will require ever more
integration
18
Three CIMs for inter-domain interaction

• Power Load Management (TC57)
• Financial Instruments (ISO20022)
• Enterprise Scheduling (CalConnect)

19
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

20
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

21
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)

22
There are many standards, select the right one
for the job
