Abstract: A method of controlling a dual fuel engine configured to receive a first fuel and a second fuel includes operating the engine using the first fuel, measuring a current load of the engine, sending a first signal to a first fuel system to deliver an amount of the first fuel to the engine, and determining at least one first operating parameter associated with the engine. The method also includes determining an engine load estimate based on the first signal and the at least one first operating parameter, comparing the engine load estimate to the measured load, and based on the comparison, determining, an adjusted engine load estimate to compensate for a drift in the first fuel system.

Abstract: Systems and methods for managing loads on a power grid are provided. In some embodiments, the load control system includes one or more power sources connected to a power grid. A method includes determining, by a first genset connected to a power grid, a power average at a first rate, and generating, by the first genset, a filtered power average. The filtered average includes the power average at a second rate. The filtered power average is used in a second algorithm to balance the load share of power sources on the power grid.

Abstract: A method for controlling a dual fuel engine system includes determining a friction power loss amount of an internal combustion engine of the dual fuel engine system, where the friction power loss amount is based on an engine speed of the internal combustion engine and a friction torque estimate. The method also includes determining an accessory power loss amount of a power of the internal combustion engine, where the accessory power loss amount is based on the engine speed and an accessory torque estimate. The method further includes estimating a net engine power amount based on the accessory power loss amount and a brake power amount of the internal combustion engine, estimating an indicated diesel power, and estimating, based on the estimated net engine power, a first indicated engine power and a first gas power.

Abstract: Systems and methods for managing loads on a power grid are provided. The load control system includes one or more energy sources connected to a common bus and a first device connected in series between the common bus and a first load. The first device may be an automatic transfer switch. The first device may include switching hardware configured to connect and disconnect the first load from the common bus and a load control circuit configured to cause the first load to disconnect from the common bus after a pre-determined amount of time detecting a trigger.

Abstract: Systems and methods for determining a remaining useful life (RUL) of a component of an engine system are provided. A method includes: receiving component data comprising sensor data corresponding to a component and engine data; pre-processing the component data by removing a first set of sensor data values that correspond to a first set of engine data values of the engine data; aggregating the pre-processed component data by grouping a second set of sensor values of the sensor data; determining a RUL for the component based on a RUL model that correlates at least a portion of the aggregated data to RUL values; adjusting the RUL based on at least one of detecting a service event or determining that one or more sensor data values of the sensor data are outside a predetermined range of values; and providing the RUL to a user device.

Abstract: A method for controlling a dual fuel engine system includes determining a gas flow target for an internal combustion engine of the dual fuel engine system, where the gas flow target is based on a gas power target of the internal combustion engine, a thermal efficiency estimate of the internal combustion engine, and a lower heating value (LHV) within the internal combustion engine. The method also includes adjusting the gas flow target based on at least one of a measured gas temperature or a measured gas injector pressure and determining at least one base gas injector command based on the adjusted gas flow target, a gas substitution rate estimate, and a gas substitution rate target. The method further includes determining, based on the at least one base gas injector command, a gas injector command for at least one engine bank.
