Abstract

An energy management system includes a controller that receives a signal representative of current electrical generation. A storage source stores energy from the current electrical generation associated with the controller. The controller predicts the amount of storage of energy in said storage source over time, receives pricing information, includes a model of a temperature system of a building, and includes a comfort model of a user. The controller selects a desirable temperature based upon the current electrical generation, the stored energy, the pricing information, the building model, and the comfort model.

Claims

1. An energy management system:

(a) a controller that receives a signal representative of current electrical generation;

(b) a storage source to store energy from said current electrical generation associated with said controller;

(c) said controller predicting the amount of storage of energy in said storage source over time;

(d) said controller receiving pricing information;

(f) said controller including a model of a temperature system of a building;

(g) said controller including a comfort model of a user;

(h) said controller selecting a desirable temperature based upon said current electrical generation, said stored energy, said pricing information, said building model, and said comfort model.

2. The energy management system of claim 1 wherein said controller receives a temporal input including at least one of (1) time, (2) day, and (3) season.

3. The energy management system of claim 1 wherein said current electrical generation includes at least one of (1) a photovoltaic source, (2) a water source, (3) a wind source, (4) an ocean source, (5) a geothermal source, and (6) a generator source.

4. The energy management system of claim 1 wherein said amount of storage is based upon historical information.

5. The energy management system of claim 4 wherein said amount of storage is based upon local weather.

6. The energy management system of claim 1 wherein said pricing information includes at least one of (1) current pricing, (2) historical pricing, (3) future pricing, and (4) time of day.

7. The energy management system of claim 1 wherein said controller receives at least one of an outdoor humidity input and an outdoor temperature input.

8. The energy management system of claim 1 wherein said controller receives a desired indoor temperature.

9. The energy management system of claim 8 wherein said desired indoor temperature is temporal based.

10. The energy management system of claim 1 wherein said model of said building is based upon an outdoor temperature, an indoor temperature, parameters of said building, and a target temperature.

11. The energy management system of claim 1 wherein said comfort model is user adjustable.

12. The energy management system of claim 1 wherein said controller includes a tradeoff factor for said pricing and said comfort.

13. The energy management system of claim 1 wherein said controller receives a demand response event.

14. The energy management system of claim 12 wherein said tradeoff factor for said pricing and said comfort is based on a monthly electricity bill limit input from user.
