如今，它是一个共同关心的现代电网和能源管理系统，以获得一个最佳的运行管理，考虑能源成本，污染物排放和安全性，系统中的插入式电动汽车（PEV）的存在。在本文中，多目标优化问题解决的电源调度在一个典型的微电网，而PEVs被视为一个随机因素。居住在城市中的PEV被认为是可能的负载和/或发电量，这取决于它们如何与公用电网相互作用。一种新的随机方法被用来计算24小时预期的电力需求和发电的车辆聚集在市政停车场。该问题的目标函数是电压安全裕度最大化和总功率损耗、总电能成本和电源总排放量最小化。基于不同的情况下，PEVs穿透对基本负荷，电压分布的影响，以及目标函数的值，进行了评估。数值结果显示了不同的PEV车队的影响，以及对未来微电网的操作。
Nowadays, it is a common concern for modern electrical networks and energy management systems to derive an optimal operation management considering energy costs, pollutant emissions, and security, of the system in the presence of plug-in electric vehicles (PEVs). In this paper, a multiobjective optimization problem is solved to schedule power sources in a typical microgrid, while PEVs are viewed as a stochastic factor. PEVs residing in a city are considered as probable loads and/or generations depending on how they interact with the utility grid. A novel stochastic methodology is used to calculate the 24 h expected power demand and generation of vehicles aggregated in municipal parking lots. The objective functions of the problem are voltage security margin to be maximized and the total power losses, the total electrical energy costs, and the total emissions of power sources, which should be minimized. Based on different scenarios, the impact of PEVs penetration on base load, voltage profile, and also the value of objective functions, are assessed. Numerical results show the effect of different fleets of PEVs, as well as on the operation of future microgrids.
