Technical process information

Automated bids are a function of manual bids

All Initial Bids are to be submitted manually.

The latest manual bid is called the Reference Bid.

All physical components and pricebands of the Reference Bid are inputs into the algorithms and these values are preserved in the Algo bid.

Not all periods will necessarily be solved by the algorithms, for example the late rebidding period (optional), past periods or beyond the solve time horizon (optional). If a new Reference Bid is detected then the dispatch intervals of the Reference Bid will be submitted for the dispatch intervals not solved by the algorithms.

If a new Reference Bid is not detected then the Current (or Active) Acknowledged Bid will be submitted for the dispatch intervals not solved by by the algorithms. The Current Acknowledged Bid is used so that components of an earlier Algo bid moves into the late rebid period and then into the dispatch interval. This helps ensure that the late rebidding period has a bid structure that is formulated by the algorithm.

For FCAS bids, the algorithms derives and allocates the optimal volume across the ten BandAvail MWs entirely from scratch. The BandAvail MWs of a manual FCAS bid are not consumed by the algorithms.

For Energy bids, the algorithms reallocates a limited optimal volume of BandAvail MWs from the Reference Bid. Therefore the BandAvail MWs of a manual Energy bid are consumed by vAdvisor and the bulk of the bid structure is preserved. The limited volume that can be reallocated is a Trader Parameter called Trader delta Limit Volume, TdLV.

The following diagramme shows how the final Algo Bid is a composite of the Last Acknowledged Bid, The Last Acknowledged Manual Bid (reference bid) and the Modified Bid that was optimised by the solver, and which consumed the Reference Bid.
