METHOD AND APPARATUS FOR BALANCING POWER ON A PER PHASE BASIS IN MULTI-PHASE ELECTRICAL LOAD FACILITIES USING AN ENERGY STORAGE SYSTEM
First Claim
1. A system for managing power delivery, comprising:
- a power monitor that is in electric communication with a first phase and a second phase of a multiphase electric line at an electric load location, and is configured to measure the power transferred through the first phase and the second phase; and
a system controller that is configured to receive information regarding the power transferred through the first phase and the second phase from the power monitor, and use the received information to control a transfer of energy from or to the first phase of the multiphase electric line from a bidirectional power converter that is in communication with an energy source.

Abstract
Embodiments of the present invention may include control methods employed in multiphase distributed energy storage systems that are located behind utility meters typically located at, but not limited to, medium and large commercial and industrial locations. These multiphase distributed energy storage systems can operate semi-autonomously, but may be in frequent contact with a cloud-based optimization engine that is configured to develop energy control solutions based on various data inputs and to communicate these energy control solutions to one or more of the distributed energy storage systems. Due to characteristics of the electric load location and/or the use of on-site power generation, imbalances in the power draw per phase can be created within the electric load location. Therefore, embodiments of the invention may include systems and methods that are used to control and/or limit the imbalance in power flowing through one phase versus other phases at the electric load location.
