System process

How automated bids are related to manual bids.

All Initial Bids are submitted manually.

The latest manual bid is called the Reference Bid.

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

For FCAS bids, vAdvisor allocates the optimal volume across the ten BandAvail MWs. The BandAvail MWs of a manual FCAS bid are not consumed by vAdvisor.

For Energy bids, vAdvisor relocates a limited optimal volume of BandAvail MWs in the Reference Bid. Therefore the BandAvail MWs of a manual Energy bid are consumed by vAdvisor. The limited volume that can be relocated is a Trader Parameter called Trader delta Limit Volume, TdLV.

How manual bids impact the submission process.

The vAdvisor solve cycle begins approximately 3 minutes into a dispatch interval when updated predispatch and p5min data are published and loaded. vAdvisor solve cycle then takes approximately 30 seconds to complete. At the end of a solve cycle vAdvisor checks if a new manual bid has been acknowledged during the 30 seconds of the solve cycle before submitting a new vAdvisor bid.

When a manual bid is submitted while Submit Mode is ON it is therefore possible that vAdvisor will not submit an offer for one or two dispatch intervals. The impact on vAdvisor offers is that one or two dispatch intervals at the end of the late rebidding period will have been optimised 5 or 10 minutes earlier than if the manual bid had not been submitted.
