【摘要】：为解决住宅小区、充电站内充电设施无法同时为多辆电动汽车最优充电的问题,以低压直流多接口充电设施为优化研究对象,提出多目标、分层分区的有序充电优化控制模型,使得充电设施运营商的收益最高,同时配电网的网损最低,电压降落始终未越限,并能在配电网电压降落越限时紧急放电,最大限度减少电动汽车负荷对其他负荷的影响。在此基础上,采用序列二次规划算法和动态规划算法进行求解,通过IEEE 34节点算例分析验证了该模型和算法的有效性。仿真结果表明:有序充电控制策略的引入在减少网损和电压降落的同时,使得充电运营商的经济效益有较大增加,较好地满足了多方面的最优需求。分层优化增强了优化控制方案的实时性、可操作性、可扩展性,使之更易于工程应用。
[Abstract]:In order to solve the problem that charging facilities in charging station can not be optimal charging for multiple electric vehicles at the same time in residential area, a multi-objective, hierarchical and orderly charging optimization control model is put forward, which takes low-voltage DC multi-interface charging facility as the optimization research object. At the same time, the network loss of the distribution network is the lowest, the voltage drop has not exceeded the limit, and the emergency discharge can be achieved when the voltage drop of the distribution network exceeds the limit, thus minimizing the influence of electric vehicle load on other loads. On this basis, sequential quadratic programming algorithm and dynamic programming algorithm are used to solve the problem. The validity of the model and algorithm is verified by IEEE 34 node analysis. The simulation results show that the introduction of orderly charging control strategy not only reduces the network loss and voltage drop, but also increases the economic benefits of charging operators, and meets the optimal demand in many aspects. Hierarchical optimization enhances the real-time, maneuverability and expansibility of the optimal control scheme, and makes it easier to be applied in engineering.
