  1. Interaction for EITC W. T. Cox 2010-05-04 Draft 4

  2. Zoom in on Interoperation • 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 DREvents Aggregator- Operator Signals and responses Participant- Operator

  3. A Slice Through the Notification Tree DREvent Participant- Operator Participant- Operator Participant- Operator Participant- Operator Aggregator- Operator Participant- Operator Participant- Operator Participant- Operator Participant- Operator Participant- Operator Participant- Operator Participant- Operator Participant- Operator ISO Aggreg Agg Client Industrial Pk Tenant

  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)
