This paper presents a voltage optimization control approach based on the coordination of battery storage, heat storage, and gas storage to handle the problem of grid voltage fluctuation in multi-energy systems. First, the system's various operation modes for electricity, heat, and gas were investigated, and a coupling model of an energy system with multi-energy storage was developed. Second, a collaborative optimization model based on the energy storage properties of distributed energy storage. According to the American Council for an Energy-Efficient Economy, switching from conventional wire ropes to PU-coated multiple-rope belts has significantly increased the energy efficiency of lifting mechanisms, so applying this knowledge to the design of gravity energy storage systems appears to be a promising next step.

In recent decades, clean heating technologies have been developed, and several tactics have been implemented to improve the heat transmission performance of energy storage radiators. Nonetheless, the combined heat storage/release effect achieved by increasing the thermal conductivities of PCMs and the radiator has received little attention, and the energy consumption efficiency required consideration of the cascading and stratification effects. Long-term energy storage devices on a massive scale are required to radically decarbonize the energy system using variable wind and solar energy. Electric Thermal Energy Storage (ETES) is a commercially accessible system that stores intermediate thermal energy in a packed bed of low-cost natural rocks.
