Create Instruction Profiles The Instruction Profile function calculates a piecewise linear trajectory over time, for each Dispatch Instruction, taking into account a subset of the Generator Unit’s input data listed in paragraphs 9 to 16 with the following criteria: In order to derive Dispatch Quantities (qDuoh(t)) for each Generator Unit, u, for each Bid Offer Acceptance, o, in Period, h, the following profiles shall be created: Physical Notification Instruction Profile input data in paragraphs 9 to 14; and Pseudo Instruction Profile using input data in paragraphs 9 to 13 plus paragraphs 15 to 16. In to derive Dispatch Quantities (QDuγ) for each Generator Unit, u, in Imbalance Settlement Period, for the purpose of Undelivered γ, Quantity calculation and Uninstructed Imbalance calculation, an Uninstructed Imbalance Instruction Profile shall be created using input data in paragraphs 10 to 13. Each section of the piecewise linear Instruction Profile for a Generator Unit shall be produced in sequence by stepping through the sequence of Dispatch Instructions and/or Pseudo Dispatch Instructions, for the Generator Unit as follows: The MW/Time Co-ordinates from the previous segment of the Instruction Profile be retrieved. For the initial segment of the Instruction Profile the MW/Time Co-ordinate is the end MW/Time Co-ordinate from the end segment of the Instruction Profile calculated for the previous Day. Where an initial MW/Time Co-ordinate is not available for the Generator Unit from the previous Instruction Profiling run, the Target Instruction Level for the latest Dispatch Instruction for the Generator Unit prior to :00 on the Day shall be used as the initial Instructed Quantity for the Generator Unit. The active Dispatch Instruction or Pseudo Dispatch Instruction shall be identified using the MW/Time Co-ordinates from the previous segment of the Instruction Profile and the Instruction Effective Time that corresponds to that Dispatch Instruction or Pseudo Dispatch Instruction. The active Dispatch Instruction or Pseudo Dispatch Instruction shall be validated by the Market Operator using the MW/Time Co-ordinates from the previous segment of the Instruction Profile, the Target Instruction Level, the Instruction Code and Instruction Combination Code using the rules specified in Table 8 and Table 9.
