Embodiment Construction

[0043] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0044] The present invention takes a charging dispatching system composed of 5 electric vehicles as an example, and its communication network topology relationship is as follows figure 1 As shown, the specific implementation steps are as follows Figure 4 Shown:

[0045] 1) Set system parameters: given the number of electric vehicles in the charging dispatching system N=5, τ=0.2, β=1, ψ=1, Ω i =0.03, Φ 1 =30kWh, Φ 2 =20kWh, Φ 3 =18kWh, Φ 4 =25kWh, Φ 5 = 40kWh,

[0046] 2) Describe the communication network topology of the charging dispatching system: set a communication connection coefficient a ij , if information interaction can be performed between the i-th electric vehicle and the j-th electric vehicle, then set a ij =τ; otherwise, set a ij = 0; the connection coefficient of the i-th electric vehicle itself where i=1...

Abstract

The invention discloses an electric vehicle charging scheduling method based on an event triggering consistency algorithm. The method considers the balance among factors such as system economy, power distribution level limitation and electric vehicle battery performance degradation. In order to effectively reduce the communication pressure of the network, an event triggering mechanism is adopted in the process of transmitting and updating the individual electricity price of the electric vehicle. Based on a proposed event triggering consistency algorithm, the problem of distributed electric vehicle charging coordination is solved, and an optimal charging strategy of the system is obtained. According to the invention, on the basis of ensuring that the charging scheduling task is effectively completed, on-demand transmission of the individual electricity prices among the electric vehicles is realized, the communication pressure of the network is obviously reduced, the communication congestion of the network is avoided, and the safe and stable operation of the whole electric vehicle charging scheduling system is ensured.

Description

technical field [0001] The invention belongs to the field of electric vehicle charging scheduling, and in particular relates to a distributed charging scheduling method for electric vehicles based on an event-triggered consistency algorithm. Background technique [0002] In recent years, with the rapid development and popularization of new energy vehicles, new energy vehicles have gradually entered our lives. However, with the development of the new energy vehicle industry, the charging problem of electric vehicles has also emerged. Among them, the charging scheduling problem It is a basic problem in the research and application of electric vehicles. Its purpose is to reduce the operating cost of the system and improve the reliability of the system operation by using related algorithms. At present, the traditional optimization methods for electric vehicle charging scheduling are all based on centralized control methods. However, centralized control is particularly dependent...
