基于配变负载动态调节的电动汽车充电功率控制系统

Electric Vehicle Charging Power Control System Based on Dynamic Adjustment of Load Distribution

基于充电设施接入在公共变压器前提,对应设置充电功率控制系统,节约充电设施投资成本。根据现场实验验证情况,对前期部署的电动汽车负荷功率控制策略进行调整:在配变重过载时,根据两级变压器容量及负载情况,对相应充电负荷进行动态调整,实现减轻或消除配变重过载的目标。调整后的功率控制策略,在考虑电网运行安全的同时,兼顾了充电用户需求,对充电车辆电池寿命更加友好。

Based on the charging facilities are supplied by public transformers,a corresponding charging power control system is set up to save investment costs in charging facilities.Based on experimental verification,when the distribution transformer is overloaded,charging load is adjusted dynamically corresponding transformer capacity and real-time load to achieve the goal of reducing or eliminating the distribution transformer overload.The adjusted power control strategy not only considers the safety of power grid operation,but also takes into account the needs of charging users,making the battery life of charging vehicles more friendly.
