This invention relates to the field of energy consumption simulation technology, specifically to a method and system for simulating the energy consumption of unmanned equipment using hybrid power systems. It solves the technical problem in existing technologies where the quasi-steady-state model neglects mechanical response lag and dynamic coupling losses, leading to distorted energy consumption predictions during simulation. The method includes: acquiring the dynamic characteristics corresponding to the mechanical response lag state of the power system at the current simulation moment; the dynamic characteristics include the battery compensation power used to characterize the power gap and the compensation power change rate used to characterize the severity of the operating conditions; determining a generator efficiency reduction factor based on the compensation power change rate to characterize the proportion of efficiency reduction caused by the generator's magnetic field establishment lag; and correcting the baseline energy consumption data determined based on the steady-state characteristic spectrum according to the generator efficiency reduction factor, battery compensation power, and compensation power change rate, and outputting the corrected energy consumption simulation results.
