Abstract: A system may determine configuration information associated with a power system for a work site that includes one or more power sources. The system may determine respective operation parameters of the one or more power sources and one or more performance criteria associated with the power system. The system may determine a baseline operation plan for the power system. The system may identify an optimization analysis technique and may process, using the optimization analysis technique, the configuration information associated with the power system, the respective operation parameters of the one or more power sources, and the one or more performance criteria associated with the power system to generate the optimized operation plan for the power system. The system may cause, based on the baseline operation plan for the power system and the optimized operation plan for the power system, one or more actions to be performed.

Abstract: A system and method for synchronizing a frequency of plurality of variable frequency generators with a variable frequency load over a variable frequency bus independent of a frequency conversion stage. A synchronization controller is configured to determine an optimal bus frequency of the variable frequency bus based on at least one power demand requirement of the variable frequency load operatively connected to the variable frequency bus. With the optimal frequency, an available power range supplied by the plurality of variable frequency gensets at the optimal bus frequency can be determined. The synchronization controller then asymmetrically loads the variable frequency load to the plurality variable frequency gensets at the optimal bus frequency based on the operating range of each variable frequency genset and recursively updates the optimal bus frequency based on operational statistics of the asymmetrically loaded variable frequency gensets.

Abstract: A system and method for variable frequency voltage regulation is presented. The system includes a variable frequency bus and a variable frequency load directly connected to the variable frequency bus. A plurality of variable frequency gensets are directly connected to the variable frequency bus. Each variable frequency genset includes a genset controller configured to select set points based on a selected frequency response curve of the variable frequency bus. A variable frequency voltage regulator is configured to regulate an electrical output of the variable frequency generator based on the selected set points. The system includes a voltage regulation controller configured to determine a desired bus frequency based on the variable frequency load, and determine an optimal frequency response curve based on the desired bus frequency and a frequency response model of each VFG. The selected frequency response curve is updated based on the determined optimal frequency response curve.

Abstract: An engine controller to control a plurality of engines is disclosed. The engine controller may determine that power to a load is to be increased, wherein the load is configured to be powered by one or more of the plurality of engines; determine that an engine, of the plurality of engines, is configured to provide supplemental power to the load after a temperature of the engine satisfies a threshold, wherein the threshold corresponds to a warm-up operation of the engine being completed; determine that the temperature of the engine does not satisfy the threshold; obtain, via an operator interface, an authorization to bypass the warm-up operation of the engine; and bypass, based on obtaining the authorization, the warm-up operation for the engine to permit the engine to provide instantaneous power to the load.

Abstract: A hybrid energy system including a controller that is coupled to at least one generator set and to at least one energy storage device. The controller is configured to cause the at least one generator set to operate at a first operational speed and a second operational speed in response to a change in the load. The controller receives notice that the at least one energy storage device is providing energy to the load and, in response thereto, to changes the amount of energy that the at least one generator set is providing to the load by causing the at least one generator set to operate at a third operational speed.

Abstract: A system for commissioning a machine such as an internal combustion engine includes commissioning probes, and a user interface having a computer receiving test data from the commissioning probes. The computer is structured to store a commissioning profile for the machine on a memory, and to populate the commissioning profile based on a compensation factor that depends on a difference between a performance response of ancillary equipment connected with the machine and an expected response. The computer outputs a commissioning suitability signal based on comparing the commissioning profile to a target profile.
