Average recent load projection

The Average Recent Load Projection register estimation routine can extrapolate registers forward, based on the last two (2) available registers. It can use mid-point registers (for example, from a pickup read) in addition to boundary registers, and can use both actual and estimated registers.

​If the estimation is done with Low selected in the Reading Quality Level field, the estimated register read will be marked with an X status to indicate the low quality.

As an example scenario, let's say that the meter stops communicating on April 28. The routine will estimate the midnight register for April 29 00:00 using the last two actual midnight registers (April 27 00:00 and April 28 00:00). If the Reading Quality Level is set to Low, on the next day, the routine will estimate the midnight register for April 30 00:00 using the April 28 00:00 register (actual) and the April 29 00:00 register (estimated). It can use the April 26 14:30 midpoint register and Apr 28 00:00 as the anchor registers. The routine first calculates the average daily consumption (ADC) as the difference between the two anchor registers, divided by the minutes between the two anchor registers. The routine then calculates the estimated register read as:

closest preceding anchor register + (ADC * number of minutes between register gap and closest preceding anchor register)

The estimation set skips this routine if two anchor registers that meet the specified Reading Quality Level setting are not available. As an example, let's say a meter stops communicating and available registers are an actual register for April 28 00:00 and an estimated register for April 29 00:00. If the Reading Quality Level is set to High, this routine marks the estimated register reads with a status of ESTAVGLOADPROJ and uses only the actual reading for estimation.

If there has been a critical configuration change between the anchor registers or between the anchor register and the register gap, the estimation is skipped.

The routine uses the same estimation logic regardless of how the data is imported: ARI, SRI/SRI-E, manual edit, or pickup read via MDUS. It can run as part of an automated estimation or a manual estimation.
