ECS Users Group,
     I was wondering if anyone is using ECS for residential load control. I am
at a point where I need an algorithm (hopefully not too complex) or a "logical
approach" to develop one, to do load shedding during the demand interval.
     I have installed the metering for both analog watts and digital watthour
telemetry. This includes watt transducers (individual metering of L1 & L2 with
totalizing after assignment of engineering units) and a contact off the
watthour meter. I also integrate the analog over the hour for comparison to
the DKWH. Accumulators are kept for hour, day, month and year. I have also
done a little cost forcasting based on current power use. My Service Entrance
is 200 amp,120/240 single phase.
     Also in place is the load shedding control equipment and sensing to
determine their run/on-off status.
     By the way, the Micro Redac interface easily handles all this. The math
was a little difficult but it gets the job done. I have not tried Mark's new
32 bit math.
     Also if you have opinions on residential "peak splitting" or TOU with
demand billing I would be interested in hearing from you.

Thanks, Larry C.
