1
Q

What is the difference between critical validations and VEE rules?

A

Critical validations are technical data checks that ensure we can read and perform VEE on the measurements– example, invalid device ID.

Then VEE rules are used to validate, estimate, and edit measurements from a business perspective– example, high-low check, spike checks, etc.

Q

What is VEE eligibility criteria used?

A

A VEE rule may optionally have eligibility criteria that controls if the rule is applied. This feature can reduce the number of VEE groups required by an implementation, because it allows a single group to have conditional VEE rules. So eligibility criteria determine if a VEE rule will be called.

Q

How can factors be used to dynamically assign VEE groups?

A

The “VEE Group Matrix (Factor)” rule allows for a Factor to determine which VEE Rule gets executed based on defined characteristics.

D1-AVEER-FCT - This VEE rule algorithm uses the factor configured on the rule to determine a VEE group, and then calls the VEE processor to execute the rules for that group.

The rule can be configured to produce an error if no VEE group is returned upon evaluation of the input factor. Otherwise, if no VEE group is returned, the rule exits without error.

Q

Can multiple estimation process be called for the same IMD?

A

Yes, All rules can be called multiple times from a single VEE group. Calling multiple estimation rules is often a good technique to estimate data.

For example, one rule can be called to fill gaps, then another rule called to scale the interval data up or down to agree with the corresponding registered ratings.

Q

How are multipliers used? How many standard multipliers does MDM include?

A

During the prepare for VEE stage, the system applies the product of the channel and installation multipliers to the pre-VEE consumption.

Q

What are the three VEE exception severity levels?

A

Info: Used to highlight something interesting, but not sufficient to cause the initial measurement to be put into the Exception state. Exceptions of this category can be used to report on the frequency of interesting, but not fatal issues.

Issue: Used to report a problem that will prevent the initial measurement from being finalized. Multiple “issue exceptions” can be created during VEE processing. If at least one issue exists after all rules have been applied, the initial measurement is transitioned to the Exception state.

Terminate: Used to report a severe issue that will cause the VEE process to stop and the initial measurement to be transitioned immediately to the Exception state. Only one terminate exception can be issued (as the first one causes VEE to stop on an initial measurement).

Q

Are exceptions deleted?

A

Exceptions are not deleted when an initial measurement is adjusted or corrected. After any issues are corrected or the initial measurement is overridden (or manually completed), the exceptions persist in a closed state for reporting purposes.

Q

Can VEE reprocessing be automated?

A

A template can be used to generate TOU data for TOU maps whose SPI divides evenly into the template’s SPI”.
Choose the best choice on what possible TOU data will be generated by the TOU Map template with 60 SPI value:

Q

Consider a rate that has different prices depending on:
a. The season of the year (winter, spring, summer, fall)
b. The time of day (peak, off-peak, shoulder)
c. The actual temperature as compared to the historic average (normal, hotter, colder)
How many TOU codes need to be set-up?

A

This rate would require 36 TOU codes (4 seasons * 3 time of days * 3 temperature bands)

22
Q

When is consumption aggregated?

A
  • The system periodically aggregates consumption in batch (using a deferred monitor on the aggregator MCs)
  • Users can re-aggregate real-time if they can’t wait or if the original aggregation needs to be redone due to incorrect admin or master data
  • Users can create ad hoc aggregations “on the fly” and these will persist in the database
  • Aggregation typically lags the current date by a few days to give the system time to upload and VEE the consumption; the amount of lag time is configured by the implementation
  • Aggregation is always performed through a given “through time” (e.g., 12am) rather than through the time of aggregation
  • Note: Exam only ask you to choose 4 correct answers. The incorrect choice is “Users can create ad hoc aggregations “on the fly” and these will NOT persist in the database“
