Problems solved by technology

[0003] At the same time, in order to reduce the emission of carbon dioxide gas and curb the trend of global warming, the promotion and application of pure electric vehicles has attracted more and more attention. However, disorderly charging of a large number of pure electric vehicles will affect the normal operation of the power grid, which will not only Generate a large harmonic current, reduce the power quality of the power supply system, and when the pure electric vehicle power battery is charged during the normal power consumption period or peak power consumption period, the additional charging current demand will increase the burden on the power supply system and affect the power grid The safe and stable operation of a large number of pure electric vehicles, the contradiction between the disorderly charging of a large number of pure electric vehicles and the normal operation of the power grid has become increasingly prominent
[0004] At present, there is no strategy and system for coordinated control of wind power generation and charging and discharging of pure electric vehicles

Embodiment Construction

[0029] The invention is a coordinated control system for orderly charge and discharge of pure electric vehicles combined with wind power generation. It utilizes the power battery to charge and obtain energy from the grid when the load is low and the wind power is strong, and sends power back to the grid when the load is peak. At the same time, harmonic control is carried out in each power battery charging station to improve power quality. The present invention transmits the information of each charging station to the power grid dispatching command center, and the power grid dispatching command center judges the state of the current power system according to wind power prediction, load prediction and power grid state monitoring, and generates a corresponding charging control mode. Power grid, wind power and power battery are all favorable control strategies. When the wind power is small and the power load of the grid is large, the power battery will send power back to the power...

Abstract

The invention relates to the technical field of wind power generation, in particular to a wind power generation-combined ordered charge and discharge coordinated control system of a pure electric vehicle. The system is characterized in that: information of each charging station is transmitted to a power grid dispatching center, the power grid dispatching center judges the state of the current power system to generate a corresponding charging control mode, and then, the information is transmitted to a charging station concentrated coordination monitoring system to carry out information interaction; the power gird dispatching center transmits a pitch peak instruction to each dynamic battery, namely a dynamic battery group, through a communication network of the charging station concentrated coordination monitoring system; and the dynamic battery group receives the pitch peak instruction to realize pitch peak and feeds back residual electric quantity to a power grid at the same time. According to the system disclosed by the invention, an advantage complementation relation among wind power generation, charge and discharge of the electric vehicle and power gird stabilization is realized and coordinated; the acceptability of wind and electricity is improved; the harmonic pollution caused by disordered charge of the pure electric vehicles and the adverse influence on the power grid are reduced to the greatest extent, and the utilization efficiency of wind and electricity and the stabilization level of the power grid are improved.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a coordinated control system for orderly charge and discharge of pure electric vehicles combined with wind power generation, which is a coordinated control system for orderly charge and discharge management of pure electric vehicles. Background technique [0002] In recent years, the wind power industry has developed rapidly, and more and more wind farms are connected to the grid. Wind power generation is not only highly random, intermittent and uncontrollable, but also has obvious anti-peak characteristics. In order to ensure the safety of the power grid, the wind must be abandoned, and the abandoned wind not only causes energy waste, but also brings damage to the wind turbine and shortens the life of the wind turbine. The contradiction between large-scale wind power grid integration and grid security and stability has become increasingly prominent. [0003] At t...
