Abstract
Power supply systems and methods for controlling such systems are provided. One power supply system includes a generator set configured to provide an electrical output to an electrical bus, over which power is supplied to heavy equipment. The power supply system further includes a computerized controller configured to be coupled to an energy storage element, wherein the computerized controller is configured to couple the energy storage element to the electrical bus in advance of a predicted increase in demand upon the electrical bus to maintain a substantially constant voltage on the electrical bus during the predicted increase in demand and prevent a drop in voltage on the electrical bus that would otherwise result from the predicted increase in demand. The predicted increase in demand is anticipated by the computerized controller as forthcoming based upon extrapolation, at least in part, from data related to a past operation of the heavy equipment.
