The invention discloses an unmanned aerial vehicle hybrid power supply system and method. The hybrid power supply system of the unmanned aerial vehicle comprises an energy storage power supply, one or more power generation power supplies and a hybrid power supply controller. The energy storage power supply and the power generation power supply are DC bus output and are directly connected in parallel; and the hybrid power supply controller is electrically connected with the energy storage power supply and the power generation power supply and is used for transmitting control signals and measurement information. According to the hybrid power supply system of the unmanned aerial vehicle, the voltage (electric quantity) maintaining function of the energy storage power supply is realized by adopting cascade control, the load current is regarded as current loop disturbance, so that the voltage (electric quantity) of the energy storage power supply is stably maintained near a preset value, and meanwhile, absorption or release of the load to the current of the energy storage power supply can be quickly compensated; and through the design of the current distributor, cooperative power supply of multiple power generation power supplies is realized.
