Problems solved by technology
However, these two control methods are relatively simple, and there are the following problems: 1) The actual charging scheduling results may be unacceptable to the user due to the neglect of the user's subjective wishes, so that the EV cannot be effectively scheduled; Appropriate and reasonable control is likely to bring new load peaks during low-price periods; 3) This management method is a centralized control mode. With the increase of EV scale, its calculation amount, communication overhead, and bandwidth will increase rapidly. At this time Centralized control is no longer applicable

Embodiment
[0047] Embodiment In conjunction with the accompanying drawings, the concrete steps of the technical solution of the present invention are as follows:
[0048] Step 1. Scene layout and parameter initialization settings:
[0049] 1) Select a charging pile in a residential area as a control network and predict the initial load L of the day based on the historical conventional load 0 .
[0050] 2) Set the time interval range of the charging pile network as T S = 16:00 to T of the next day E =8:00 and equal division [16:00 8:00] with dt=15min is N=64 period;
[0051] 3) Set the transformer power limit Bkw of the charging pile network, and the industrial time-of-use electricity price is a yuan / kw h from 7:00-23:00, and b yuan / kw h from 23:00-7:00;
[0052] 4) All EVs in the service are set to have the same maximum charging power P max =8kw, battery capacity C=40kw h, expected to be fully charged, charging efficiency η=0.9;
[0053] 5) The number of electric vehicles served by...

The invention provides a distributed electric automobile ordered charging control method. The method comprises the steps of carrying out initialization setting on a controlled charging network and inputting t-period electric automobile charging data; constructing a t-period virtual dynamic time-of-use power price according to a network power price and load; calculating an electric automobile charging load in a distributed mode according to the t-period virtual dynamic time-of-use power price and charging data, updating a power distribution network load, and updating next-period electric automobile charging data; and finishing ordered charging control over all electric automobiles until the whole control interval range is finished. The method is applied to load calculation of a large-scale electric automobile access power network, the charging cost is the minimum, the activity of users participating in ordered charging is improved, and a load curve can be gentled.
Description
technical field [0001] The present invention mainly relates to the field of the Internet of Things, in particular to the technical field of the new energy Internet. Background technique [0002] With the deepening of the energy crisis and the intensification of air pollution hazards, people are increasingly aware that new energy is the main development direction of future automotive technology. Electric vehicles have attracted the attention of governments due to their cleanness, environmental protection, high efficiency and energy saving. The development of electric vehicles (EV) is an important means to solve the energy crisis and environmental pollution. In recent years, the central and local governments have successively issued a series of subsidy and support policies, making the domestic electric vehicle industry develop rapidly. [0003] With the popularization of electric vehicles in the future, large-scale electric vehicles connected to the grid for charging will have...
