Adaptive load shedding
First Claim
1. A load shedding system for shedding loads within a building to maintain power demand below a predetermined limit, said loads affecting actual conditions in associated zones within said building with respect to desired conditions, said system comprising:
- condition sensing means for sensing said actual conditions in said zones of said building;
connecting means adapted to be connected to said loads within said building; and
,control means connected to said condition sensing means and to said connecting means for shedding said loads in order of those loads affecting those zones having the least deviation between said actual conditions and said desired conditions being shed first and those loads having the most deviation being shed last to maintain said demand below said predetermined limit.

Abstract
A load shedding system for shedding loads within a building to maintain power demand within the building below a predetermined level (i.e. current demand limit) wherein the loads which can be shed are those which affect or control actual conditions in the zones associated with the loads is disclosed having condition sensors for sensing conditions such as temperature in the zones of a building and a control apparatus responsive to the conditions being sensed by the condition sensors and connected to the loads for shedding the loads in order of those loads affecting or controlling the zones having the least deviation between the actual condition and a desired condition being shed first and those loads affecting or controlling those zones having the most deviation being shed last to maintain power demand below the predetermined level.

5. A load shedding system for shedding loads within a building to maintain power demand within the building below a demand limit wherein said loads which are shed are those loads which control the temperatures in zones supplied with air treated by said loads, said loads having a desired temperature to which said actual temperature is controlled, said system comprising:
-
temperature sensing means for sensing said actual temperatures in said zones of said building; and
,control means connected to said temperature sensing means and to said loads for shedding said loads in order of those loads controlling those zones having the least deviation between the actual temperatures and the desired temperatures being shed first and those loads controlling those zones having the most deviation being shed last to maintain said demand below said limit. - View Dependent Claims (6)
