SYSTEM AND METHOD OF POWER CONTROL FOR AN ENERGY STORAGE CHARGING STATION
First Claim
1. A system comprising:
- a control unit comprising a processor and a communication interface operably coupled to the processor, wherein the communication interface is configured to communicate with one or more charging stations electrically coupled to receive electrical power from a power distribution grid and configured to selectively charge one or more energy storage devices connected to the one or more charging stations,wherein the processor of the control unit is configured to generate first control signals for communication by the communication interface to the one or more charging stations to control transfer of at least one of reactive power or active power from the one or more charging stations to the power distribution grid based at least in part on a load cycle profile of one or more electric machines electrically coupled to the power distribution grid.

Abstract
A system includes a control unit having a processor and a communication interface. The communication interface is configured to communicate with one or more charging stations that are electrically coupled to receive electrical power from a power distribution grid and that are configured to selectively charge one or more energy storage devices connected to the charging stations. The processor is configured to generate first control signals for communication by the communication interface to the one or more charging stations to control transfer of reactive and/or active power from the charging stations to the power distribution grid. The control signals are generated based at least in part on a load cycle profile of one or more electric machines electrically coupled to the power distribution grid.
