The invention discloses a charging pile power supply method suitable for an expressway service area and a control system. According to the power supply method, each charging pile can select one from a plurality of power supply and distribution networks to take power; the power supply method comprises the following steps: acquiring charging power required by a charging pile based on a charging request of the charging pile; collecting the power of a distribution transformer corresponding to each power supply and distribution network, and obtaining the power supply power capacity residual value of each distribution transformer; and selecting the optimal power supply and distribution network to supply power to the charging pile based on the charging power required by the charging pile and the residual value of the power supply power capacity of each distribution transformer. The method solves the problem that the single-side capacity of the high-speed service area does not meet the charging requirement, but the capacity of the opposite-side distribution transformer is left but cannot be complemented with each other, reduces the capacity expansion pressure of a power grid of the service area, and improves the charging capacity and the power supply and distribution asset utilization rate of the high-speed service area.
本发明公开了一种适用于高速公路服务区的充电桩供电方法及控制系统,该供电方法使每个充电桩都可从多个供配电网中选取一个进行取电;该供电方法包括:基于充电桩的充电请求,获取充电桩所需的充电功率;采集各供配电网对应的配电变压器的功率,获得各配电变压器供电功率容量剩余值;基于充电桩所需的充电功率、各配电变压器供电功率容量剩余值,选择最佳供配电网对该充电桩进行供电。本发明解决了高速服务区单侧容量不满足充电需求而对侧配电变压器容量有剩余却无法给予互济的问题,降低服务区电网的扩容压力,提升了高速服务区的充电能力和供配电资产利用率。
