Methods and systems are disclosed for determining a power distribution for a plurality of power sources of a hybrid power system. The plurality of power sources may comprise an energy storage device, preferably a battery. The energy storage device may be associated with a charge rate and/or a discharge rate, and with a state of charge. The plurality of power sources may further comprise one or more electric-power generators electrically coupled to the energy storage device. An electric-power generator may be associated with a maximum amount of provided power, Pmax, and may also be associated with a power-specific fuel consumption, sfc(P), defining a quantity of fuel consumed per quantity of energy provided as a function of provided power. The method may comprise determining a discharging equivalent specific fuel consumption based on the respective power-specific fuel consumptions of the respective one or more electric-power generators. The discharging equivalent specific fuel consumption may define an estimated amount of fuel that will be consumed by recharging the energy storage device. The method may, additionally or alternatively, comprise determining a charging equivalent specific fuel consumption obtainable by determining the amount of fuel consumed according to the discharging equivalent specific fuel consumption at a discharge rate that is equal to a given charge rate. The method may further comprise determining a power distribution based on at least the discharging equivalent fuel consumption and/or the charging equivalent fuel consumption.
