1. A system including a first industrial machine and a second industrial machine, the system comprising:
a power distribution system configured to provide power to the first industrial machine and the second industrial machine;
the first industrial machine including a first power control system configured to monitor power usage of the first industrial machine,
compare the power usage of the first industrial machine to a first power threshold,
transmit power usage information of the first industrial machine to the second industrial machine when the power usage of the first industrial machine is greater than or equal to the first power threshold,
receive power usage information from the second industrial machine,
control power usage of the first industrial machine based on the power usage information received from the second industrial machine; and
the second industrial machine including a second power control system configured to
monitor power usage of the second industrial machine,
transmit the power usage information of the second industrial machine to the first industrial machine,
receive the power usage information from the first industrial machine,
compare the power usage of the second industrial machine to a second power threshold,
control power usage of the second industrial machine based on the power usage information received from the first industrial machine,
wherein the second power control system is configured to reduce the power usage of the second industrial machine when the power usage of the first industrial machine is greater than or equal to the first power threshold and the power usage of the second industrial machine is greater than or equal to the second power threshold.
