With the increasing proportion of renewable energy

the power grid is facing intermittent and fluctuating challenges

and large-scale long-term energy storage technology is urgently needed. As a mature technology

pumped storage is limited by geographical conditions

but its information and intelligent transformation provides an important reference for the development of new productivity. Gravity energy storage technology has become a research hotspot because of its advantages of flexible site selection

high efficiency and environmental friendliness. In this paper

the principle and development status of vertical and sloping gravity energy storage technologies are systematically analyzed

and the key issues such as weight control

grid-connected technology and system efficiency are discussed by integrating them into the informatization practice of pumped storage projects. It is pointed out that gravity energy storage technology needs to make breakthroughs in heavy-weight transmission

cluster control and material research and development

and informationization and intelligence will be the important development direction in the future. The engineering management and control experience of pumped storage can provide reference for it.
