Abstract: A method may include receiving power supply-related information, cost-related information, power demand-related information, and operational priority or site configuration-related information associated with hydraulic fracturing rigs. The hydraulic fracturing rigs may be each associated with a fuel consumption component or an emissions component. The method may further include receiving operational data and determining operational parameters based on the operational data and emissions output predictions for the hydraulic fracturing rigs. The method may further include outputting the operational parameters to a computing device or a controller. The method may further include, based on outputting the operational parameters, receiving operational feedback data and determining whether to modify the operational parameters. In addition, based on the outputting, the method may include determining whether to modify the operational data based on determining to not modify the set of operational parameters and modifying the operational data based on determining to modify the operational data.

Abstract: A power system for powering a load is provided. The power system includes a plurality of power sources with each power source including an engine. A SCR system is associated with the engine of at least one of the plurality of power sources. A controller is in communication with the plurality of power sources. The controller is configured to receive engine operation information, emission output information associated with each engine and conversion efficiency information associated with the SCR system and selectively apportion the power demand presented by the load between each of the plurality of power sources based on minimizing total engine emissions across the plurality of power sources and using the engine operation information, the emission output information and the conversion efficiency information.

Abstract: A system for allocating power generation between a constant speed generator set and a variable speed generator set. A controller determines an operating power demand from on-line consumers, and determines an anticipated transient power demand from a new consumer or one with an increasing power demand. The controller allocates the electrical power response between the generator sets to meet both the operating power demand prior to a transient condition and the total power demand upon the occurrence of the transient condition. The allocation may be based upon operating modes of the system.
