Market Operations prepares and submits bids and offers into the market. Bids and offers are evaluated against needs, offsetting bids and offers, and then accepted, matched, or rejected. The evaluated bids will lead to load curtailment when it is economically feasible, the matched bid and offer curtail load, instead of accepting the offers from supply side resources within the ancillary services market. This use case proposes a computer system known as the Distributed Resources Availability and Control System (DRAACS), which would serve as a clearinghouse for demand response requests submitted to the AMI system. Some of these requests may originate from Market Operations for economic dispatch purposes, and some may originate from the Grid Control Center for reliability purposes. This use case deals specifically with economic dispatch requests.
