This invention discloses a combined solar power generation and gravity energy storage power supply system and method. The power supply system includes a solar power generation system, a gravity energy storage system, and an intelligent control system. The intelligent control system presets a power generation threshold and dynamically controls the gravity energy storage system to store or release energy based on the difference between the real-time solar power generation and the threshold, thus stabilizing the combined output power. The gravity energy storage unit adopts a symmetrical double-sloped support tower and a dual energy storage structure design, achieving bidirectional conversion between electrical energy and gravitational potential energy through a clutch mechanism. The intelligent control unit dynamically adjusts the floating threshold based on predicted wind speed and historical power fluctuation rate, improving the system's adaptability to different wind fields.
