This invention relates to an energy dispatching method and system for a gravitational potential energy power generation system, belonging to the field of power generation system technology. The method includes: calculating the power gap by measuring the power of grid nodes and comparing it to a baseline, and then converting this into the target height of the gravity block. Based on this, the potential energy power generation capacity is deduced, the gravity block lifting and lowering sequence is planned, and the motor torque is allocated. Finally, based on the torque curve, the frequency converter and speed are adjusted to drive the gravity block, achieving dynamic conversion and balance between gravitational potential energy and grid electrical energy. This solves the technical problems of traditional solutions, which result in a disconnect between mechanical action and grid demand, inaccurate power output adjustment, and the generation of useless power surges or vacuum periods during acceleration and deceleration, which can worsen the power quality of the local grid.
