In an embodiment of the present invention, the power generation method further includes identifying the current power consumption of the power grid, and if the current power consumption of the power grid is at the peak of power consumption, the power generation process is performed.

The load capacity of the power grid can be improved by releasing the counterweight 12 to drive the power generating device 3 to generate electrical energy output for supplying the power grid during the peak of power consumption.

Among them, the current electricity consumption situation of the power grid can be identified according to the time period. For example, 24 hours a day is divided into two time periods, of which 8:00 to 22:00 is the peak of electricity consumption, and 22:00 to 8:00 of the next day is the valley of electricity consumption.

In addition, it is also possible to determine the time period of the peaks and valleys of electricity consumption according to the power consumption data feedback of the power grid within a period of time, and then control the energy storage process and power generation process; or, it can also be based on the real-time power consumption data of the grid usage. Feedback, adjust the time period division of the peak and valley of electricity consumption in a timely manner. Of course, other methods may also be used to determine the peaks and valleys of electricity consumption, which are not limited here.

In the embodiment of the present invention, multiple gas tank potential energy power generation systems can also be used in a network, and the multiple gas tank potential energy power generation systems can synergistically generate electricity during the peak of electricity consumption to generate larger electric energy for supplying the power grid. . And when the electric wave valley is used, the hoisting device 5 is used to drive the hoisting device 5 to lift the counterweight 12, and the electric energy is converted into the gravitational potential energy of the counterweight 12, thereby reducing the waste of electric energy in the grid and improving the utilization rate of electric energy. And when the electric wave peak is used, the counterweight 12 is released to generate electric energy for supplying the power grid, which plays the role of peak-shaving and valley-filling.
