Abstract: A method may include receiving information related to operation or a configuration of a hydraulic fracturing system. The hydraulic fracturing system may include a plurality of electric power source outputs and a plurality of hydraulic fracturing rigs. The method may further include performing, based on the information, asymmetric power management of the plurality of electric power source outputs. The method may further include performing, based on the information, asymmetric load management of the plurality of hydraulic fracturing rigs.

Abstract: In some implementations, a controller may monitor an available power supply of at least one power source for a system for hydraulic fracturing, and a current power demand of the system. The controller may determine, based on monitoring the available power supply and the current power demand, whether a relationship between the current power demand and the available power supply is indicative of an impending power failure. The controller may cause, based on determining that the relationship between the current power demand and the available power supply indicates the impending power failure, reduction of flow rates of one or more fluid pumps of the system to reduce the current power demand.
