Energy storage system
First Claim
1. A genset system comprising:
- a genset coupled to an alternating current (AC) bus; and
an energy storage device coupled to the AC bus, the energy storage device having a controller;
wherein the controller of the energy storage device is configured to monitor the genset through one or more signals and control a flow of power into or out of the energy storage device to keep the genset within a selected range of operating conditions.

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. The energy storage system further includes a controller configured to control the bidirectional inverter based on one or more signals received from the generator set coupled to the inverter via an AC bus. The controller is configured to, based on the one or more signals, control the bidirectional inverter to store power generated by the generator set in the energy storage device and transmit power from the energy storage device to a load driven by the generator set to maintain the generator set within a range of one or more operating conditions.
