Patent attributes
A system for controlling power in a facility having an electrical system including an energy storage device and a generator and an associated fuel tank. The fuel tank provides fuel to the generator and has a gauge indicating remaining fuel. Both the energy storage device and the generator operate. The generator may be used to provide power to the facility, the energy storage device, or both simultaneously. A first power consuming device imposes a first load connected to the electrical system and second power consuming device imposes a second load connected to the electrical system. The system receives information related to the loads and calculates an initial estimated run time of the energy storage device, and information related to the first load and information related to the second load. The system selectively removes the second load in a simulation and calculates a second run time of the energy storage device.
