Embodiment Construction

[0016] Preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention, and are not intended to limit the protection scope of the present invention.

[0017] At present, among the charging and swapping stations that provide electric energy supply for electric vehicles, there are charging and swapping stations that use photovoltaic systems to generate electricity, AC charging piles and DC charging piles that use power directly from the grid, and there are also battery energy storage for backup during peak periods. feed back to the grid. The purpose of the present invention is to solve the problem of how to optimize the allocation of energy in time and space, and realize the reasonable distribution and scheduling of electric energy among photovoltaic systems, grid systems, energy storage syste...

Abstract

The invention belongs to the technical field of power charging and conversion of an electric vehicle, and in particular relates to a light charging, storage and conversion integrated station and a power distribution method thereof. The invention aims to solve the problem of relatively single energy storage and flow process in an existing charging and conversion power station. For this purpose, the light charging, storage and conversion integrated station comprises a photovoltaic system, a power distribution system, a charge-discharge system, an energy storage battery and a control system. By reasonably using and allocating first electric energy generated by the photovoltaic system, second electric energy, received by the power distribution system, of a power grid, third electric energy of the energy storage battery and power supplement demand of the electric vehicle, the electric energy among the photovoltaic system, the power grid, the energy storage battery and the electric vehicle is flexibly switched. Moreover, in order to response to an economic adjustment means of the difference between peak and valley of the power grid, peak shaving and load shifting are achieved by the photovoltaic system and the energy storage battery.

Description

technical field [0001] The invention belongs to the technical field of charging and swapping electric vehicles, and in particular relates to an integrated light-charging-storage-swapping station and a power distribution method thereof. Background technique [0002] With the promotion of electric vehicles, how to timely and effectively provide electric energy supply for electric vehicles with insufficient power has become a problem that manufacturers and car owners are very concerned about. The mainstream solution in the current market is the electric vehicle charging and swapping station that adopts the charging mode and battery swapping mode, and configures AC slow charging piles or DC fast charging piles in the parking spaces or directly replaces exhausted batteries with fully charged battery packs. Group. In addition, there are charging and swapping stations that use photovoltaic power generation, and technologies such as grid connection and battery energy storage have a...
