Problems solved by technology

[0003] In order to reduce the impact of electric vehicle charging on the new load brought by the power grid, the existing technology usually adopts a peak-shaving and valley-filling scheme. An electric vehicle charging system, which includes a power supply area, an energy storage area, a charging area and a management area, stores the electric energy during the low valley of the power grid through the energy storage device and uses it for the peak load of the power grid, but this scheme only uses the The electric energy is stored and used at the peak time, and no corresponding time-sharing control strategy is formulated according to the peak, valley, and flat periods of the power grid. It is impossible to realize the dynamic allocation of charging power according to the charging demand of different periods, so it is impossible to improve the power grid. The utilization rate of the energy storage device realizes the smooth transition of the peak and valley mode of the system

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to an electric vehicle flexible charging system and a control method. Background technique [0002] With the increasingly serious environmental and energy problems, electric vehicles and new energy power generation have emerged as the times require. Electric vehicles use electric energy as the main energy source, and their operation will not produce substances harmful to the environment, so they are strongly advocated worldwide. With the increasing popularity of electric vehicles, the number and power requirements of DC chargers are also increasing. DC chargers take power from the mains and convert the mains into DC power for electric vehicles through AC / DC rectification modules. Charging, when a large number of electric vehicles charge during peak load periods on the grid, can put enormous pressure on the grid. [0003] In order to reduce the impact of electric v...
