Another attribute of the Sliding Window Alg Advanced section of the DLLR object UI is Target Ramp Down Enabled. This optional attribute ramps down the target incrementally over the course of one interval. The default setting is False. The behavior prevents excessive, immediate shedding by the DLLR object. The following values are used:
Trev = revised target level
Told = target level at the time the target level is decreased
Tnew = new target level
N = number of readings of electrical consumption per demand interval
j = 1, 2, 3, ..., N
The process loops on j after each new reading of energy consumption.
Figure 2 shows the revised target level following a decrease in the target level from Told to Tnew. Notice that the revised target level follows a decreasing staircase pattern. In this example, the number of readings (N) of electrical consumption per demand interval is five. Upon a second target change within the same interval, a new stair step begins, which uses the current ramped target value (Trev) as Told.
