Load Rolling executes the following process once each minute:
-
LR sums the load ratings for all loads currently shed for load rolling.
-
If LR shedding is below the tariff target, LR selects and sheds available priority 10 loads until it reaches the currently active target for Load Rolling. Loads are shed in rotation.
-
If shedding all priority 10 loads does not reach the target savings, LR selects and sheds all available priority 9 loads until the load shedding goal is reached.
-
If shedding all available priority 9 loads does not satisfy the load shedding goal, the process continues with priority 8 loads, and so forth, until finally the priority 1 loads are shed.
Note: All loads within a load priority must be either shed or ineligible to be shed before LR sheds a load from the next highest priority. For example, if a load is configured at priority 10, it might be shed many times before a priority 9 or higher load is shed even once. Also, before a priority 8 load is shed, all priority 9 and priority 10 loads already must be shed (or be ineligible to be shed). -
If shedding all available LR loads still does not reach the target savings, the following occur:
-
The Status Indicator on the DLLR Focus view displays Trouble. (If in Monitor Only mode, DLLR instead indicates its status as Monitor Only Mode Active.)
-
The DLLR Status attribute in the DLLR Focus view reads LR cannot meet target.
-
The LR not Shed attribute under the Advanced Load Rolling section of the DLLR object UI indicates the unsheddable value.
