ENERGY STORAGE SYSTEM
First Claim
1. An energy storage system comprising:
- an energy storage device;
a bidirectional inverter configured to control a flow of power into or out of the energy storage device via a plurality of phases; and
a controller configured to control the bidirectional inverter based on a load condition on one or more of the plurality of phases, wherein the controller is configured to control the bidirectional inverter to store power generated by a generator set in the energy storage device and transmit power from the energy storage device to a load driven by the generator set in response to detecting a load imbalance between the plurality of phases.

Abstract
Systems and methods for controlling power flow to and from an energy storage system are provided. One energy storage system includes an energy storage device and a bidirectional inverter configured to control a flow of power into or out of the energy storage device via a plurality of phases. The energy storage system further includes a controller configured to control the bidirectional inverter based on a load condition on one or more phases. The controller is configured to control the bidirectional inverter to store power generated by a generator set in the energy storage device and transmit power from the energy storage device to a load driven by the generator set in response to detecting a load imbalance between the phases.
