系统会利用电网中多余的电能驱动电机，电机带动绞盘运转，通过缆绳将重物提升至山地高处。在此过程中，电能转化为重物的重力势能储存起来。根据重力势能的计算公式E=m×h×g×eh，其中：m为重物质量，g为重力加速度，h为重物提升的高度，提升高度越高，储存的重力势能就越大。

01 Energy Storage Stage
The system will use the excess electricity in the power grid to drive the motor, which will then drive the winch to operate and lift heavy objects to high places in the mountains through cables. During this process, electrical energy is converted into the gravitational potential energy of heavy objects and stored. According to the calculation formula of gravitational potential energy E=m × h × g × eh, where m is the mass of the heavy object, g is the gravitational acceleration, and h is the height at which the heavy object is lifted. The higher the lifting height, the greater the stored gravitational potential energy.

02 释能阶段

当电网需要电能时，控制重物下落，重物通过缆绳带动绞盘反转，绞盘驱动发电机发电，将重物的重力势能转化为电能并输送至电网。

02 Energy Release Stage
When the power grid requires electrical energy, the heavy object is controlled to fall. The heavy object drives the winch to reverse through the cable, and the winch drives the generator to generate electricity. The gravitational potential energy of the heavy object is converted into electrical energy and transmitted to the power grid.
