基于大规模电动汽车接入电网经济运行的研究 PAGE PAGE I 【摘 要】 为应对日益严重的能源危机和环境污染问题,电动汽车作为一种无污染零排放的绿色交通工具在世界各国得到了广泛的推广和应用。规模化的电动汽车接入将会给电力系统运行带来压力和挑战。本文根据用户充电规律，首先通过蒙特卡洛法模拟得到电动汽车无序充电情况下的日负荷曲线,结果显示在用电高峰时段无序充电会对电力系统造成很大的冲击。其次，针对如何利用电动汽车有序充电对电网实现削峰填谷效果的问题，提出了基于分时电价的优化方法。最后，对大规模电动汽车接入电网进行无序充电与有序充电进行比较，并阐明大规模电动汽车接入电网有序充电的经济性和实用价值。 关键词：电动汽车；蒙特卡洛算法；有序充电；分时电价； PAGE PAGE II 【Abstract】 In order to deal with the growing energy crisis and environmental pollution, electric vehicles as a pollution-free zero emission green vehicles in the world have been widely spread and application.The scale of the electric vehicle access will bring the power system to run the pressure and challenge.This paper according to the user charging rules, first of all by Monte Carlo simulation get electric vehicle disorderly charge of daily load curve. The results showed that the peak hours of electricity in the disordered charge will cause great impact on power system.Secondly, according to the problem of how to use the ordered charging of electric vehicles to achieve the peak load and fill effect in the grid, the optimization method based on the sub-power is presented.In the end, the disorder charging and ordered charging of the large scale electric vehicle access network are compared, and the economical and practical value of the large scale electric vehicle access to the orderly charge of the electric vehicle is expounded.
