Description
Technical Field
The invention relates to the technical field of energy storage, in particular to an automatic connection and parking system for gravity energy storage based on multiple objects.
Background
New source energy such as wind energy, solar energy and the like in China are mainly distributed in northwest regions, solar power generation is concentrated in the daytime, power loads are mainly distributed in southeast coastal regions, the power consumption ratio at night is larger, and the phenomenon causes that strong space-time mismatching exists in the power production and consumption of new energy in China. The new energy power generation is influenced by weather conditions, so that the fluctuation is large, and particularly after the direct grid connection proportion of the new energy power generation exceeds 20%, serious vicious chain accidents can occur to generate large impact on the whole power grid. Therefore, phenomena such as wind abandoning and light abandoning are often generated, and the utilization rate of new energy power is low. However, the energy storage technology with low cost, large capacity and easy addressing can effectively solve the problems of space-time mismatching and grid-connected stability, and is an important guarantee for large-scale efficient development and utilization of renewable energy and realization of green sustainable development strategy in the energy field of China.
Gravity energy storage is an old and relatively mature energy storage technology, particularly a water pumping energy storage technology, and commercial operation is realized. However, the water pumping and energy storage technology has high requirements on site selection, upstream and downstream reservoirs need to be built, the evaporation capacity of water is high, and site selection in northern areas, particularly northwest areas is difficult. The gravitational potential energy storage system for lifting heavy objects by using the slope track and the vertical shaft is widely concerned, and has superiority when being applied to arid water-deficient areas. The slope track is used for gravity energy storage, the efficiency of the gravity energy storage is closely related to the slope of the slope, the larger the slope is, the smaller the friction loss is, but a plurality of problems exist in the construction of large-slope slopes and tracks, and the influence of extreme weather, geological disasters and the like on an energy storage system needs to be considered. The vertical lifting weight is used for energy storage, the technical difficulty and the construction cost are lower if the existing or abandoned structures such as vertical shafts, beam frames and the like can be utilized, and the construction cost is also increased if the vertical beams or the vertical shafts need to be newly constructed. Aiming at a scheme of Energy storage for vertically lifting heavy objects, Energy Vault company in Switzerland proposes a structure for stacking concrete blocks into a tower by using a crane, the concrete blocks are hoisted and hoisted for Energy storage and release, and the weight of a single concrete brick can reach 35 tons. The manipulator that adopts hoist structure hoist and mount concrete piece need high load and high accuracy to grab and put, and the manufacturing degree of difficulty is big, and has the hawser to rock and be difficult to fix a position, pile a great deal of problems such as tower stability is low, has restricted its popularization and application. The great britain Gravitricity company utilizes a shaft hoist to hoist a single weight for gravity energy storage, in order to increase the energy storage capacity, the weight of the single weight is planned to be expanded to 500 tons, and the further improvement of the mass of the single weight brings challenges to the design and construction of mechanical structures such as a supporting beam frame, a hoisting system and the like. In order to solve the defects of gravity energy storage of a single heavy object in a vertical shaft, the Chinese invention patent CN202110714699.8 provides a method for transferring a plurality of heavy objects by using an automatically-driven rail trolley, if the number of the heavy objects is too large, the plurality of automatically-driven rail trolleys all need independent power supply and control systems, the integral reliability of the system is reduced, and the manufacturing, operation and maintenance costs are increased; the Chinese invention patent CN 202111173003.1 provides a multiple-object transfer method using a plurality of beams and radial beams on a portal frame, and the method also has the problems of long transverse transfer time of the objects and high manufacturing cost of the portal frame; chinese patent CN202111561732.4 of the invention proposes a method for transferring weight by using AGV forklift, but the load capacity of AGV forklift is relatively small and needs counterweight, and in addition, it is difficult to reverse the car after transferring one weight due to its special structure to further transfer weight.
