Embodiment Construction

[0048]figure 1 This is a flowchart of a method for timing charging of an electric vehicle charging pile for peak regulation of a distribution network provided by the embodiment of the present application.

[0049] First, see figure 1 , The method for timing charging of electric vehicle charging piles for peak shaving of distribution networks provided by the embodiments of the present application includes the following steps:

[0050] S1. Determine the peak period, the normal period and the trough period of the electricity consumption period of the charging pile; and, determine the allowable charging period and the required charging period of the electric vehicle to be charged;

[0051] Since electricity is used in different time periods, the corresponding electricity prices are different, and if a large amount of electricity is used in the same time period, that is, the load of the distribution network increases, it will affect the stability of the electricity consumption of t...

Abstract

The application discloses a fixed-time charging method and a fixed-time charging device for an electric automobile charging pile for peak regulation of a power distribution network. The fixed-time charging method and the fixed-time charging device are suitable for application scenes such as a charging pile at the parking side of a user, which can be occupied for a long time and has low charging current. By using the method and the device, the charging pile preferably selects a low-valley period for charging, and then normal period and final peak period according to load characteristics of a power distribution network line; an optimal fixed-time charging scheme which is most beneficial to peak regulation of the power distribution network is automatically generated, so that fixed-time charging of a to-be-charged electric automobile is realized by the power distribution network with a relatively-small electrical load, and on-site peak regulation is realized. Therefore, according to the method and the device, on the premise of meeting charging demands of the user and peak regulation demands of the power distribution network, the charging pile can select the period with lower use expenses for automatic fixed-time charging; optimal charging time is used as the reference of peak regulation of the power distribution network, and real-time communication between the peak regulation and scheduling is not needed; in addition, real-time adjustment of the load of the power distribution network line is not needed, so that a peak regulation realizing mode is simpler and more convenient.

Description

technical field [0001] The present application relates to the technical field of electric vehicle charging, and in particular, to a method and device for timing charging of electric vehicle charging piles used for peak regulation of power distribution networks. Background technique [0002] With the country's development strategy of replacing and converting non-petrochemical energy sources, and avoiding the problems of energy shortage and environmental pollution caused by traditional vehicles, electric vehicles with zero emissions and multiple energy sources are gradually being used as power sources. widely used. Electric vehicles use power charging to achieve power supply, and charging for electric vehicles is usually achieved by using charging piles configured in the distribution network. However, if electric vehicles appear in large numbers, there will inevitably be situations where multiple electric vehicles need to be charged at the same time, which will increase the l...
