摘要随着社会的发展,环境污染和能源短缺的问题越来越严重。作为新能源交通工具的电动汽车越来越受到人们的关注,电动汽车的主要优点是环境污染小和能源利用率高,而且电是可再生能源。当少数电动汽车接入电网时,并不会对电网产生影响,但是当未来大规模的电动汽车接入电网时,将会对电网的正常运行和控制带来严峻的挑战。为了应对未来大规模电动汽车接入电网,要对电动汽车负荷进行预测,然后分析电动汽车充电负荷对电网的影响。主要包括以下几个方面的内容:在对电动汽车充电负荷建模时,需要充分考虑充电功率,起始荷电量,起始充电时间以及电动汽车的规模这些因素的影响;重点分析不同类型电动汽车的运营状况和充电特性,应用蒙特卡洛模拟法计算电动汽车充电负荷,预测未来电动汽车充电负荷曲线。46131

ABSTRACT With the development of the society, the proplem of environmental pollution and energy shortage are becoming more and more serious. Electric vehicle have been paid more and more attention as a new ground translt’system. It’s major advantage are environmentally compatible and high power utilization., and electricity is a renewable energy source. when a small number of electric vehicles are connected to the power grid, it does little impact on the power grid.but, large scale electric vehicles access to the power grid will bring serious challenge to the normal operation and control of the power grid. In order to deal with the large scale of electric vehicles access to power grid, we should predict the load of electric vehicle and discuss the influence on the power grid of the electric vehicle charging load. The chief contents is as follows: in the modeling of the electric vehicle charging load, need fully think about the effect of initial charging time, the effect of charging power, the scale of the development of the electric vehicle and the initial charge capicity; we should focus on the analysis of different types of electric vehicles of the operation status and charge characteristic. We should use the monte carlo silumation method to predict the electric vehicle charging load curve.
