基于区域配电网有序充电系统的设计与实现

Design and Implementation of Orderly Charging System Based on Regional Distribution Network

摘要: 为减小规模化电动汽车无序充电行为对区域电网的影响，即减少区域电网负荷峰值的增加，电动汽车作为可响应需求的移动负荷，其对电网的影响力随着规模的扩大日益凸显。为了发挥其作为可控负荷的潜力，促进电网与用户间的互动，本文提出基于区域配电网的有序充电的系统，该系统可实现充电桩状态和配电网负荷数据的监测与传输，随后根据有序充电策略的设计原则和管理策略，并结合当前区域内配电网用电负荷、电动车辆运营情况和车辆电量等多种情况，使用多维度多目标算法自动生成有序充电策略。最后以某区域内的充电为应用场景，经过多次试验，结果表明按生成的控制策略，通过引导电动汽车进行有序充电，可以达到降低日负荷峰谷差的目的。

Abstract: In order to reduce the impact of large-scale disorderly charging behavior of electric vehicles on the regional power grid, that is, to reduce the increase of peak load in the regional power grid, as a mobile load that can respond to demand, the influence of electric vehicles on the power grid becomes increasingly prominent with the expansion of the scale. In order to make full use of its potential as controllable load and promote the interaction between power grid and users, an orderly charging system based on regional distribution network is proposed. The system can monitor and transmit the battery status and load data of distribution network. Then, according to the design principle and management strategy of orderly charging strategy, according to the regional distribution of power grid load, electric vehicle operation and vehicle power, combining multi-dimension and multi-objective, the orderly charging strategy is automatically generated. Finally, the charging in a certain area is an application scenario. After many experiments, the results show that according to the generated control strategy, the daily load peak-valley difference can be reduced by guiding the electric vehicle to charge orderly.
