A new type of charging pile power distribution system

Abstract

A new charging pile power distribution system. The charging pile system includes a charging pile main control module, a charging pile controlled module, a charging billing module, a charging controller module, and a charging power supply module. The microgrid subsystem includes a wind power generation module, a photovoltaic power generation module module, power storage module, and micro-grid control module; the city grid subsystem includes a city grid module, a power load module, a city grid power consumption estimation module, a primary power storage module, a city power grid control module, and a micro-grid grid-connected module ; It can solve the waste of electricity in scattered micro-grids, which is beneficial to the peak-shaving and valley-filling of the national grid; through the monitoring of the charging power of each charging pile in the area and the statistics and regulation of the user's electricity consumption according to the electricity consumption estimation module of the city grid, the charging and distribution Control the charging power to provide charging users with a variety of charging modes for users to choose. By controlling the change of charging unit price, users are encouraged to use full power charging during low power consumption periods, so as to maintain the efficient circulation of electric energy in the city grid.

Description

technical field [0001] The invention relates to the technical field of electric vehicle charging, in particular to a novel charging pile power distribution system. Background technique [0002] An electric vehicle (BEV) refers to a vehicle that is powered by a vehicle-mounted power supply, drives the wheels with a motor, and meets the requirements of road traffic and safety regulations. Due to its smaller impact on the environment than traditional cars, its prospects are widely optimistic. Electric vehicles need charging piles to supplement electric energy. The charging of a small number of electric vehicles will not have a great impact on the power grid. However, due to the state's support for electric vehicles in recent years, the use of electric vehicles has greatly increased. The number of vehicles will reach 60 million. Assuming that these electric vehicles are charged at the same time, the peak power will reach 500 million kilowatts, resulting in excessive load on the...

Electric vehicles need charging piles to supplement electric energy. The charging of a small number of electric vehicles will not have a great impact on the power grid. However, due to the state's support for electric vehicles in recent years, the use of electric vehicles has greatly increased. The number of vehicles will reach 60 million. Assuming that these electric vehicles are charged at the same time, the peak power will reach 500 million kilowatts, resulting in excessive load on the power grid, especially during the peak power consumption period in summer or winter, and the stable operation of the power grid cannot be guaranteed.

[0003] With the development of my country's technology and economy and the increasing attention to energy conservation and emission reduction, the state vigorously supports the construction of micro-grids. Micro-grids are a power network that includes power generation, power distribution, and power consumption. Micro-grids mainly use photovoltaic power generation, Wind power generation is the mainstay, and the load is connected to energy storage equipment. However, due to the sparse distribution of the micro-grid and the large environmental factors, the power supply is unstable. With the rise of more and more household charging piles, the existing technology Lack of power distribution system for charging piles
