Embodiment Construction

[0036] Embodiment of Electric Vehicle Charging Power Regulation System

[0037] This embodiment provides a charging power adjustment system for electric vehicles. The adjustment system is provided with a control device for adjusting the charging power of electric vehicles. The control device is the core of the adjustment system. A software program related to the vehicle charging power regulation method is used to realize the regulation of the charging power. In addition, in addition to the control device, the regulating system may also include other components, however, other components are not the focus of the present invention, and will not be described here. Therefore, the focus of the control device is on the method for regulating the charging power of electric vehicles, not on the hardware structure for implementing the method. It can be a background monitoring system such as an industrial computer, or other hardware control systems. This embodiment provides a A specific...

Abstract

The invention relates to an electric automobile charging power regulating method and system. The method includes firstly determining scheduling plan power of electric automobile charging power, and then solving actual charging power of various electric automobiles under demand response management according to the scheduling plan power, wherein the scheduling plan power is related to electric load,the higher the electric load is, the lower the scheduling plan power is, the actual charging power is positively correlated to the scheduling plan power, the lower the scheduling plan power is, the lower the actual charging power of the electric automobile is. The charging power is regulated, particularly the charging power of the electric automobile is reduced at the electricity utilization peak, and the charging power of the electric automobile is not limited in the valley of electricity utilization. The system can achieve orderly guide and real-time power control in charging of the electric automobile, reduces charging load to a certain degree at the electricity utilization peak on the basis of the full use of the existing distribution network resources, realizes peak shaving of the power grid, stabilizes the difference between the peak and the valley of the power grid, reduces load fluctuation of the power grid, and improve stability of the power grid.
