This paper studies the problem of capacity optimization configuration for the hybrid system of gravity energy storage and pumped storage. Combining the characteristics of these two energy storage methods, a new optimization model is proposed to realize their synergistic effect. Through optimal configuration, the overall energy storage cost can be reduced under the premise of ensuring system stability and operational efficiency. By means of mathematical modeling, the paper analyzes factors such as system power demand, energy storage capacity, and operational constraints, and proposes a corresponding optimization algorithm. The hybrid system of gravity energy storage and pumped storage has obvious advantages in coping with large-scale power load fluctuations and improving energy utilization efficiency. The results of this study provide theoretical support and practical significance for the flexibility and stability of energy systems.
