摘要
近年来,随着电动汽车数量增多,配电网负荷波动增大、电压超限现象频繁,无法充分发挥用户侧潜力。为了兼顾电网安全运行与用户收益,利用遗传算法和二阶锥规划建立了一种双层优化调度模型,实现电动汽车与配电网之间的协同优化控制。上层优化以电网稳定为出发点,综合考虑负荷变化、电压控制与网损状态;下层优化则围绕用户收益,以动态电价为手段引导电动汽车合理有序地进行充放电。选用IEEE 33节点系统作为仿真算例,验证了该模型不仅能有效保障配电网安全平稳运行,而且在一定程度上增加了用户的经济收益,实现车与电网双方共赢。
In recent years,with the increase in the number of electric vehicles(EVs),the load fluctuation of the distribution network has increased,and voltage over-limit phenomena have occurred frequently,which has failed to fully tap the potential of the user side.In order to balance the safe operation of the power grid and the benefits of users,a double-layer optimal dispatching model is established with genetic algorithm(GA)and second-order cone programming(SOCP)to achieve the collaborative optimal control between EVs and the distribution network.The upper-level optimization takes the stability of the power grid as the starting point,comprehensively considering load changes,voltage control and network loss status.The lower-level optimization focuses on user benefits and uses dynamic electricity prices as a means to guide EVs to charge and discharge reasonably and orderly.Finally,the IEEE 33-node system is selected as a simulation example,which verifies that this model can not only effectively ensure the safe and stable operation of the distribution network,but also increase the economic benefits of users to a certain extent,achieving a win-win situation for both EVs owners and the power grid.
