Abstract: An energy-saving seawater desalination device using power generated in complementary cooperation of wind energy and light energy, and a control method are provided. The device comprises an electrical control cabinet, a photovoltaic power generation component, a wind power generation component, an energy storage device, an electric heater, etc. The present invention supplies power for power loads of a seawater desalination system through solar power generation and wind power generation in a grid-connected system, and cooperates with the traditional power grid to maximize and localize the utilization of new energy power and reduce the waste of resources. In an off-grid system, the photovoltaic power generation component and the wind power generation component convert redundant power into other forms of energy resources for energy storage through a battery or an electric heater under the condition that the generating capacity is enough.
