Embodiment Construction

[0045] Embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0046] Define the following technical terms:

[0047] EV (electric vehicle): An electric vehicle, powered by the on-board power supply, needs to be charged when the power is insufficient.

[0048] Time slot: Divide 24 hours a day into T time slots on average, and each time slot has Hour.

[0049] Conflict set: For each time slot, the vehicles that need to be charged in this time slot among the currently reserved vehicles form a set, which is called the conflict set of this time slot. The conflict set is expressed as V(t)={v i |vehicle v i In the charging state at time slot t}, where t∈[t s , t e ].

[0050] Conflict set inequality: If the size of the conflict set exceeds the number of charging piles in the charging station, then the charging station cannot meet the charging needs of all vehicles. For each time slot t, the collision set inequality ...

Abstract

The invention provides a method for efficiently allocating charging piles based on conflict sets, and belongs to the technical field of electric vehicle charging scheduling in smart grids. The present invention adjusts the charging time for the reservation requests of electric vehicles sent successively by judging the conflict set to meet the reservation requests that may not be acceptable originally, and makes the working time of the charging pile more compact, thereby improving the success rate of electric vehicle reservations and Utilization of charging piles. In addition, it adopts the method of unified distribution by time period, and coordinates dispatching of vehicles between charging piles, and adjusts the distribution of vehicles among charging piles, so as to meet as many charging requests as possible and balance the working power among charging piles. And every time, for multiple reservation requests that have been accepted, the charging pile allocation scheme aimed at power balance can allocate specific charging piles on the premise of meeting the charging needs of all reserved vehicles, and get the best charging pile. Allocation scheme to improve the working power of charging piles.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle charging scheduling in smart grids, and in particular relates to a method for efficiently allocating charging piles based on conflict sets. Background technique [0002] With the development of new energy vehicles for nearly two decades, the world's major automotive powers have expressed that they will upgrade it to the national strategy, and China also regards new energy vehicles as one of the important strategic industries. Sales of electric vehicles have been increasing in recent years, and demand for charging them will also spiral upwards. However, at the same time, charging stations (piles) are not fully popularized, and it is often difficult to meet the electricity demand of all users. In order to use limited resources to provide charging services for more electric vehicles, many scheduling schemes for electric vehicle charging have been proposed at home and abroad. [0003] Howev...
