Embodiment Construction

[0024] The present invention will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.

[0025] figure 1 Shown is a schematic diagram of the overall functional structure of the integrated system of distributed energy and electric vehicle wireless power supply based on magnetic resonance coupling technology. The distributed energy generation system 1 includes a photovoltaic power generation system, a wind power generation system and a wind-solar hybrid power generation system. Photovoltaic power generation system and wind power generation system can supply power independently, or consider the complementarity between photovoltaic power generation and wind power generation, combine the two, and form a wind-solar hybrid power generation system for power supply according to the optimal ratio of wind and wind power to achieve the maximum system power output.

Abstract

The invention relates to a distributed energy source and an electric vehicle wireless power supply integrated system based on a magnetic resonance coupling technology. The system comprises a distributed energy source power generation system, a resonance magnetic coupling wireless electric energy transmission system and an electric vehicle (EV). The distributed energy source power generation system and the resonance magnetic coupling wireless electric energy transmission system form an organic integrated system by virtue of a form of a direct current micro-grid, and are centralized together in a proper connecting mode by matching with an energy storage system and related electric equipment to meet a charging requirement of the electric vehicle and characteristic control of a renewable energy source, thereby achieving elimination and utilization on the spot of the renewable energy source by the electric vehicle. The invention solves many problems generated by a distributed energy source grid, and avoids a great pressure on the structure and running of a power grid caused by a large amount of electric vehicles which are charged by plugging into the power grid. According to the invention, a resonance magnetic coupling wireless electric energy transmission technology is adopted to supply power to the electric vehicle, and the defects of a conductive charging mode are avoided, which is helpful for promoting popularization of electric vehicles.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle wireless power supply, and in particular relates to an integrated system of distributed energy and electric vehicle wireless power supply based on magnetic resonance coupling technology. Background technique [0002] Unlike large-scale renewable energy power generation connected to the transmission grid, which requires long-distance transmission, renewable distributed power generation is close to the load end, which can effectively reduce transmission loss. It has the advantages of small and flexible, high efficiency, and low investment cost. It is a smart grid One of the important directions of development. However, due to the influence of geographical location and weather conditions on distributed power generation, the intermittent nature is strong, the output power is not stable, and the time is not consistent with the load fluctuation, resulting in a large peak-valley difference, wh...
