Abstract
Control of an electric water heater based on a two-mass model may be provided. First, a reserve capacity of an Electric Water Heater (EWH) may be determined. Next, a safe deferred time for the EWH based on the determined reserve capacity may be determined. Then a grid service event initiation may be received. In response to receiving the grid service event initiation, the EWH may be caused to not heat water for the determined safe deferred time.
Claims20
A method comprising:
- determining a reserve capacity of an Electric Water Heater (EWH);
- determining a safe deferred time for the EWH based on the determined reserve capacity;
- receiving a grid service event initiation;
- and
- causing, in response to receiving the grid service event initiation, the EWH to not heat water for the determined safe deferred time.
A system comprising:
- a memory storage;
- and
- a processing unit coupled to the memory storage, wherein the processing unit is operative to:
- determine a reserve capacity of an Electric Water Heater (EWH);
- determine a safe deferred time for the EWH based on the determined reserve capacity;
- receive a grid service event initiation;
- and
- cause, in response to receiving the grid service event initiation, the EWH to not heat water for the determined safe deferred time.
A computer-readable medium that stores a set of instructions which when executed perform a method executed by the set of instructions comprising:
- determining a reserve capacity of an Electric Water Heater (EWH);
- determining a safe deferred time for the EWH based on the determined reserve capacity;
- receiving a grid service event initiation;
- and
- causing, in response to receiving the grid service event initiation, the EWH to not heat water for the determined safe deferred time.
