Description

Technical Field

[0001] This invention belongs to the field of energy storage technology, and specifically relates to a parallel frame-type gravity energy storage and transportation system. Background Technology

[0002] To meet the requirements of carbon peaking, the country is vigorously developing clean energy power generation projects, such as wind power, solar photovoltaic power, and tidal power, which are renewable and pollution-free energy sources, thereby reducing carbon emissions from fossil fuel combustion power generation. However, clean energy power generation resources and power load are often mismatched, especially at night when the grid demand for wind power generation along the coast decreases, making it difficult to absorb the electricity. Therefore, energy storage is necessary.

[0003] Energy storage can store electricity or convert it into other forms of energy storage, thereby releasing electricity during peak demand periods and coordinating with the power grid for peak shaving. Currently, commonly used energy storage methods include physical methods such as pumped hydro storage, compressed air storage, and flywheel storage, which have limitations in terms of geographical location and involve high motor inertia and power consumption. Electrochemical energy storage methods such as lithium-ion batteries have short cycle life, are prone to environmental pollution, and pose high safety risks. Supercapacitor energy storage and superconducting energy storage have low energy density and high cost.

[0004] Gravity energy storage uses physical methods, storing potential energy by lifting a heavy object, and is pollution-free. When electricity is needed, the heavy object is released to drive a generator. However, existing gravity energy storage methods, which rely solely on lifting a heavy object, are often inefficient, store little energy, are limited by geographical conditions, have limited expansion capacity, and have high life-cycle costs.

[0005] The applicant has decided to seek technical solutions to address the above-mentioned technical problems. Summary of the Invention
