Stereo parking garage energy supply depot and method based on distributed multi-energy utilization

Abstract

The invention discloses a stereo parking garage energy supply depot based on distributed multi-energy utilization. The energy supply depot comprises a hydraulic-elevator compressed air energy storage system, a wind power generation subsystem, a solar photoelectricity subsystem, a piezoelectric subsystem and an energy management system. The hydraulic-elevator compressed air energy storage system utilizes compressed air to store remaining hydraulic energy and generates electric energy to lift a car, and is composed of a hydraulic elevator, a solar thermal collector, a heat exchanger, a pump, a turbo expander, an electric generator and a reciprocating compressor. By utilizing the solar photoelectricity subsystem, the wind power generation subsystem and the piezoelectric subsystem, solar energy, wind power and pressure energy are converted into electric energy, and the electric energy is stored into a storage battery for supplying energy to a parking garage. The stereo parking garage energy supply depot can conduct regulation and control on the storage battery and electric supply according to different usage time periods of the electric supply. By using the stereo parking garage energy supply depot, hydraulic energy can be recycled, solar energy, wind power and other various renewable energy sources can be efficiently utilized, energy is saved, emission is reduced, and the energy supply requirements for hydraulic energy of stereo parking garages and electric energy of electric cars are met.

Description

technical field [0001] The invention relates to an energy supply station, in particular to a three-dimensional parking garage energy supply station based on distributed multi-energy utilization, which belongs to the field of new energy utilization. Background technique [0002] The number of cars in my country's cities has increased rapidly, and the limited ground in the city can no longer provide enough parking spaces. The parking problem has become an urgent problem to be solved in many big cities. Building a three-dimensional parking garage is undoubtedly an important way to solve this problem. With the emergence of a large number of new energy vehicles, there will inevitably be problems such as charging difficulties in the future. Traditional energy sources and the national grid will be unable to bear the high-load centralized charging mode. [0003] The hydraulic lifting system is widely used in three-dimensional parking garages due to its advantages of large power-to-w...

AI Technical Summary

Problems solved by technology

However, when the hydraulic system realizes three-dimensional parking, there is considerable waste of hydraulic energy.

At present, the three-dimensional parking garage uses mains power as the driving power source, which is not conducive to energy saving, and the mains power has limitations. It cannot meet the lifting and lowering functions of the parking garage in remote areas and on highways, which limits the promotion and use of the three-dimensional parking garage.
