Standing data. The input is a constant that represents the tolerance of the zero test used for the Metered Energy Adjustment Factor calculation. The input’s initially programmed value = 0.0000000009.
Actual implementation of the Metered Energy Adjustment Factor (MEAF) calculations is influenced by a a product limitation whereby the software engine utilizes numbers within its cache that may have a precision beyond 9 decimal places. A number may appear to be zero as it is written to and read from the database, yet the number utilized within the cache during the calculation may appear as a very small, non-zero number. The ZeroTolerance input is used to check whether the value of a given BD = 0 within the tolerance specified by the ZeroTolerance input. The zero test is performed in a MEAF ratio’s calculation for which the BD is used as a divisor, in order to provide the correct mathematical results when the BD’s value is considered infinitesimal.
DA Energy Schedule (in MWh) that corresponds to the flat hourly Day-Ahead Schedule (DAS). It is composed of Day-Ahead Minimum Load Energy, Day-Ahead Self-Scheduled Energy, and Day-Ahead Bid for a given resource and Dispatch Interval.
Flag (as a 0/1 Boolean value) that indicates for a given Dispatch Interval whether (1) or not (0) a specified resource is expected (as part of an instructed operation) to be in a startup, shutdown, or MSG transition period, or a period in which it is crossing over a Forbidden Operating Region, or the time period for which a Dispatch Operating Point correction is performed due to a verbal Dispatch Instruction issued by the CAISO Operator, as long as the resource is in fact in the operational mode instructed by the CAISO.
Ramping tolerance (in MWh) measured as the Expected Energy Dispatch Operating Point (DOP) less the Expected Energy Dispatch Operating Target (DOT) over a 5-minute Dispatch Interval for a given resource. The input is intended to be added to the Tolerance Band as ramping tolerance in the configured calculation of the Performance Metric Tolerance Band (as specified in the “CAISO Formula” section herein).
A count (as an integer value) that serves as the lthreshold for the number of Settlement Intervals over a 2- hour adjacent window where in the interval a resource can exceed the Performance Metric Tolerance Band without having its bid cost basis mitigated as a consequence of persistent deviation. The count is stored in the Settlements system as resident “factor” data. The currently specified count threshold value = 6.
Variable Energy Resource Flag for Resource r. A value of “1” indicates a certified Variable Energy Resource (VER), while a “0” value indicates that the resource is not certified as a VER.
The input represents the infinite ramp rate for Generation. Its value shall be the constant “9999”. A VER is presumed to have infinite ramp rate, whereby the resource is deemed capable of instaneously correcting its output for a change in its hourly Energy forecast from one FMM Interval to the next.
The input represents the hourly Real Time Market Energy Bid Quantity (in MW) by Business Associate and resource ID.
