Technical process information

Automated bids are a function of manual bids

All Initial Bids are submitted manually.

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

Not all periods will be (re) solved by vAdvisorthe algorithms, for example the late rebidding period. If a new Reference Bid is detected then the Reference Bid will be submitted for the periods not solved by vAdvisorthe algorithms.

If a new Reference Bid is not detected then the current acknowledged bid will be submitted for the periods not solved by by vAdvisorthe algorithms. This helps ensure that the late rebidding period has bids formulated by vAdvisor and therefore NEMDE will consume bids that were formulated by vAdvisorcontinues to have values formulated by the algorithm.

• Important: any manual bid should be drafted from a bid synchronised with the current acknowledged bid. If a manual bid is drafted from, for example, a bid template, then the late rebidding period bid structure that had been previously optimised by vAdvisor will be lostoverwritten by the content of the new manual bid, irrespective of the source of the new manual bid.

For FCAS bids, vAdvisor 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 vAdvisorthe algorithms.

For Energy bids, vAdvisor relocates 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 relocated reallocated 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 The optimisation and bid allocation processes then takes approximately 30 seconds to complete. At the end of a solve cycle vAdvisor checks The Autobidder then checks to see if a new manual bid has been acknowledged during the these 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 in the current dispatch interval. .

If a new manual bid has not been found then the autobidder submits the new Algo bid. However if a new manual bid is found then the Autobidder pauses the submission process until the next dispatch interval. This is done to ensure that the new manual bid takes precedence. If the autobidder was not paused then there could be an inconsistency between the new manual bid and the algo bid.
