The utility model is a power generation system that comprehensively utilizes offshore wind power, tides, and pumped storage technology: utilizes the favorable terrain of the bay to construct tidal water storage reservoirs, and install tidal pumped water generating units. During the low tide period of the system load at night, according to the anti-regulation characteristics of wind power generation, Utilize the excess wind power to pump water to the upper reservoir. During the peak load period of the system, use the tide and the water volume of pumped water to generate electricity to realize the peak regulation and frequency regulation of the system.
