MARKETPLACE MUI VS. EIS MUI
3
Similarities• XML-based interface
– Programmatic API– Browser based User Interface (UI)
• Available via SPPNet and Internet• Certificates used for authentication and authorization
– LSA assigns roles for each user• Users may query for the following types Market data
– Private data (e.g. data previously submitted or asset owner specific market results)
– Notification data (i.e., data issued as notifications to all participants) – Public data (e.g. market clearing prices).
• Notification Push Process– 1 Primary and up to 9 additional Participant listeners can be registered per
notify service for each Asset Owner – Retry attempts for failed notifications to the Primary listener
4
Differences• Services partitioned into logical subsets
– Energy, Virtual, Reserve, etc.• Low level operations for Resource Offers
– Allows user to update individual parameters without resubmitting the whole resource offer
– Composite operation is also available to submit the complete resource offer• Authorized users can programmatically manage Notification listeners per notify
service for each Asset Owner– Add, remove and query listeners– Set priority for each listener (primary, secondary, additional)
Note: The same listener URL can be assigned to multiple notify services• Delete operations available for Demand Bids, Virtual Bids/Offers and
Notification Listeners• Asynchronous credit approval response from MUI for Virtual Bid/Offer
