1. Interaction for EITC

Draft 4

2. Zoom in on Interoperation
DREvents
Aggregator-
Operator
Signals and responses
Participant-
Operator
Recursive pairwise relationship
Participant implements aggregator interface to distribute events to its own participants
Compose appropriate security, reliability, and interaction model as appropriate for each interoperation link

5. ISO Issues and Resistance
ISO issues with varying security and reliability/confirmation of delivery requirements
Application to non-California markets and interactions
Factor out tariffs/contracts
Notification of reliability events is key to ISOs
Distribution is also key to ISOs
Price communication is relatively unimportant to ISOs
Price quote/closing price stream is important and done today
EMIX as the price quote stream

6. Participant/Real Estate Notes
Want a way to distribute events to tenants or separate owned properties
Price distribution appears to be a requirement
Needs discussion/analysis
Consistency of approach allows application to recursive ownership and notification

7. MicroGrid Notes
Each ParticipantOperator is a MicroGrid control access point (a la ESI)
Fit nested/overlapping MicroGrids into the picture on slide 3
Notification to MicroGrid-contained participants has differing security/reliabilty requirements

8. Summary of Application of EI
Signal notification paths have varying requirements
Must be able to apply/compose additional configured solutions
Compose WS-Reliable Messaging
Compose WS-Security components
Compose other needed technologies (undetermined)
Factor
Price Signals (with multiple delivery paths)
Reliability Signals (single secure and reliable path)
Environmental Signals (similar to Price)
All need individual links to have specific characteristics
Non-repudiation, privacy, confirmed/signed source
Reliability, app-level or transport-level ACK
Probably the same at each level (for each Aggregator-Operator instance)
