Power control strategies for modular-gravity energy storage plant

So far, the gravity storage power plant in CC mode already has a good compensation performance, while the gravity storage power plant with OC still has a power drop problem. Therefore, for the OC, the CSM-HD is obtained by introducing the dead zone based on the CSM-H, thus solving the power drop problem and finally getting a good compensation result.
