Electric vehicle charging scheduling method considering reservation and queuing in charging station

Abstract

The invention discloses an electric vehicle charging scheduling method considering reservation and queuing in a charging station, being applied to the technical field of electric vehicle charging scheduling in a smart power grid, aiming to solve the charging scheduling problem that two charging modes of reservation charging and on-site queuing charging exist at the same time in an existing electric vehicle charging transition stage. The electric vehicle charging scheduling method comprises the following steps: firstly, determining a scheduling time window, reasonably allocating proportions ofcharging piles accessible to users in different modes through reinforcement learning based on historical charging data information of the users in the charging station, and then intelligently switching charging modes by comparing queuing waiting time and appointment waiting time of dynamically arriving users. The charging experience of the user in different charging modes is balanced and improvedin the transition stage, and the flexibility of user charging mode selection is improved, and the resource utilization rate of the charging pile is increased.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle charging scheduling in smart grids, and in particular relates to an electric vehicle charging scheduling technology that takes both reservation and queuing into consideration. Background technique [0002] The rapid development of modern cities requires the continuous consumption of large amounts of fossil energy, but it also causes serious air pollution. Electric Vehicle (EV) has become the main trend of the future development of the automobile industry due to its characteristics of zero emission, low noise and high energy efficiency. However, the development of electric vehicles is not all smooth sailing. Limited by battery capacity and charging efficiency, the current user experience of electric vehicles is far from meeting expectations. Charging station resources are not optimally configured according to charging needs. This is of no benefit to the use of charging facilities, the ch...

Second, by intelligently switching the charging mode, the reservation user can abandon the reservation and join the queuing queue instead when he arrives at the charging station in advance. Conversely, the queuing user can also give up the queuing and make an on-site reservation, which can make timely adjustments to the dynamically changing charging needs of users to avoid There are situations where there are idle charging piles and user needs cannot be met by adjusting the charging method
