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 Reference Bid will be submitted for the periods not solved by the algorithms.

If a new Reference Bid is not detected then the current acknowledged bid will be submitted for the periods not solved by by the algorithms. This helps ensure that the late rebidding period continues to have values 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 and the Modified Bid that was optimised by the solver, and which consumed the Last Manual Acknowledged Bid.
