Abstract:
1. A method of rescheduling energy for a virtual energy load, said method comprising: computing an energy schedule for said virtual load, said energy schedule indicating an energy level to be consumed by said virtual load for each of a plurality of time intervals within a time period, said virtual load representing a plurality of actual energy loads; distributing an individual control schedule to each of said actual loads such that said actual loads in total consume energy according to said energy schedule; receiving power logging data from at least one of said actual loads during a current one of said time intervals, said power logging data indicating an amount of energy consumed by said at least one of said actual loads in said current time interval; estimating a total energy consumption of said virtual load in said current time interval; comparing said total energy consumption with said energy level from said energy schedule for said current time interval; recomputing said individual control schedules using an updated value for said energy level for said current time interval; distributing said recomputed individual control schedules among said actual loads, whereby each actual load receives its recomputed individual control schedule and whereby said actual loads in total consume energy according to said energy schedule; recalibrating a load model for each of said actual loads using logged state variables for each of said actual loads received during said current time interval, wherein said recomputing includes using an inverse model for each of said recalibrated load models in order to output said recomputed individual control schedules; and controlling said actual loads during said time period using said recomputed individual control schedules.
