【摘要】：目前,能源短缺及环境污染日益严重,电动汽车却凭借其突出的节能、环保性能,成为未来交通工具的研究首选。大规模电动汽车充电入网对电网必然会产生重大影响。为适应、满足未来电网运行的需要,有必要对电动汽车的发展做出预测,并基于此,分析其对临沂电网的影响,试图为临沂电网的发展研究做出有益的探索。本文从以下几个方面展开,分析研究其对临沂电网的影响。首先对不同类型的电动汽车充电模式进行了分析。采用蒙特卡罗法来模拟、计算不同充电下各电动汽车的充电负荷。充电负荷模型的基础上,随之分析了大规模电动汽车在自由充电及换电两种模式下入网充电对负荷特性的影响。基于充电负荷特性,又仿真分析了大量大规模电动汽车入网充电对临沂市配电网产生的影响,并从充电站规划、智能充电控制两方面提出了针对性的可行性应对策略。本文最后针对集中充电站的电池负荷特性展开分析研究,并利用PSASP软件建立了仿真模型。通过仿真分析得到了一些对充电站建设上的有益的建议和结论。
[Abstract]:At present, energy shortage and environmental pollution are becoming more and more serious. However, electric vehicles have become the first choice of future transportation by virtue of their outstanding energy saving and environmental protection performance. The charging and entering of large scale electric vehicles is bound to have a great impact on the power grid. In order to meet the needs of future power grid operation, it is necessary to make predictions for the development of electric vehicles, and based on this, analyze its impact on Linyi power grid, and try to make useful exploration for the development of Linyi power grid. This paper analyzes the influence of the Linyi power grid from the following aspects. First, the charging mode of different types of electric vehicles is analyzed. The Monte Carlo method is used to simulate and calculate the charging load of each electric vehicle under different charge. On the basis of the charge load model, the effect of charging on the load characteristics of large scale electric vehicles under two modes of free charging and switching is analyzed. Based on charging load characteristics, the influence of large scale electric vehicle charging on Linyi distribution network is simulated and analyzed, and feasible countermeasures are put forward from two aspects of charging station planning and intelligent charging control. At the end of this paper, the battery load characteristics of the centralized charging station are analyzed and studied, and the simulation model is established by using the PSASP software. Some useful suggestions and conclusions on the construction of the charging station are obtained through the simulation analysis.
