摘要

The growing number of plug-in electric vehicles (PEVs) poses challenges for the distribution system, such as voltage fluctuations and intricate power management issues. This research optimizes the charging and discharging behavior of PEVs to overcome these difficulties. To reduce power losses, peak loads, and queue, it incorporates both fast-charging and slow-charging PEVs into existing charging stations (CSs) by categorizing their state of charge (SOC) into two scenarios. A PEV discharge approach that allows users to generate revenue is proposed. Priority scheduling, which considers waiting times and queues, is employed to enhance CS revenue and mitigate voltage violations in the specified area. The average minimum and maximum final SOC for slow-charging PEVs are 0.3154 and 0.3465, respectively, whereas for fast-charging PEVs, they are 0.3188 and 0.3482. The average minimum and maximum charging durations for slow-charging PEVs are 54.344 min and 57.821 min, respectively, whereas for fast-charging PEVs, they are 10.967 min and 11.363 min. Experiments conducted on the IEEE 33-bus distribution system validate the optimization of PEV scheduling and the enhancement of system performance across various hourly PEV penetration levels.
