Method and apparatus for delivering power using external data

摘要

A control system for an energy storage system located behind a utility meter uses a unique, feedback-based, communication and control method to reliably and efficiently maximize economic return of the energy storage system. Operating parameters for the energy storage system are calculated at an external, centralized data center, and are selected to prevent electrical power demand of an electric load location from exceeding a specified set-point by discharging energy storage devices, such as DC batteries, through a bidirectional energy converter during peak demand events. The control system can operate autonomously in the case of a communications failure.

主权项

1. A method of controlling energy transferred between an electric grid and an electric load location, comprising:
monitoring a first rate of energy transfer from an electric line to the electric load location, wherein the electric line is coupled to an electric meter adapted to measure power transferred between the electric load location and the electric grid; receiving a first set of operating parameters that are created based on one or more received external inputs; and based on the first set of operating parameters, varying the energy transfer from an energy storage device to the electric line to cause the first rate of energy transfer to remain below a threshold value, wherein the threshold value varies with time.
