The invention relates to a hybrid wind and light power generation device used for ships and a control method. The power generation device comprises a ship body floating on water, a ship power device pushing the ship body to move forward, an alternating-current power grid supplying power to the power device, a storage battery connected with the alternating-current power grid, a wind power generator and a solar cell panel, wherein the wind power generator and the solar cell panel feed electric energy back to the alternating-current power grid. The control method comprises a gird-connected control method of the hybrid wind and light power generation device used for ships and a tracking control method used for the hybrid wind and light power generation device used for ships. According to the hybrid wind and light power generation device used for ships, energy can be saved and environmental protection can be achieved. Due to the fact that a solar yaw device is additionally arranged on a solar power generation device, the utilization efficiency of solar energy is improved. The hybrid wind and light neutral network PID grid-connected control method enhances the stability of a voltage of a hybrid wind and light grid-connected system, and operating speed of a grid-connected controller is increased through the powerful operation function of a DSP.
