Electrical thermal storage with edge-of-network tailored energy delivery systems and methods

摘要

A method and apparatus of controlling the electric power usage of electric thermal storage heaters and systems are based on: 1) current and recorded measurements local to the heater and building; 2) current measurements external to the heater and building; 3) forecasts communicated to the apparatus. The method also includes sending out communications about power use as well as various other local measurements. The apparatus has local controls on the electric thermal storage, including but not limited to the relays that control flow of power into the heating elements, a logic module that integrates the local controls, as well as communication channels that extend outside the building to entities capable of providing automatic forecasts and potentially other types of information not available locally.

主权项

1. An energy management system for at least one device drawing power from an electric grid, comprising:
a system having at least one controller, the system able to connect to a computer network, the at least one controller operating on an ETS heater, the ETS heater including a heat sink, wherein the system uses characteristics of the ETS heater, heated space characteristics, temperature data, current weather data, forecasted weather data, and electricity price data to operate the heater to control the draw of power from the electric grid, wherein the system controls the ETS heater such that a minimum temperature of heated space is maintained, power is drawn under a maximum price of electricity, and maximum temperature of the heat sink is not exceeded.
