Energy-saving seawater desalination device using power generated in complementary cooperation of wind energy and light energy, and control method

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. When the generating capacity is not enough, the loads are allocated to avoid the waste of energy as much as possible.
