【摘要】：气候、能源和环境问题是人类社会共同面对的主要问题。随着环境污染和能源危机的不断恶化,电动汽车作为一种有效的解决手段己在世界各国形成广泛的共识。电动汽车是否能够快速健康的发展,与之相配合的充电设施能否合理有效的规划建设起到至关重要的作用。本文首先介绍了目前主要的三种电动汽车的类型,简要介绍了各自的优缺点。根据不同的技术手段和运营方式指出了目前三种可行的充电方式,并结合其各自的使用要求给出了使用范围。接着运用充电方式的各自的特点,详细介绍了电动汽车的基础充电设施并提出本文所要使用的充电站的模式。针对主干公路独特的空间格局,结合电动汽车随机性较强、行驶距离有限的特点,运用交通流守恒原则,建立行驶在城市主干公路上的电动汽车的动态流体模型。该模型可以用数学的方法求取行驶在公路上的电动汽车的密度,进而求取到达快速充电站进行电能补充的抵达率。根据对电动汽车提供充电服务的特点,运用M/M/S排队论随机服务系统的理论,求取满足充电站服务稳定的电动汽车快速充电桩的数量和功率需求。对于交通流的随机性,通过对各个变量求期望的方法来满足模型的一般性。最后,以某条公路上的行驶规律为例,运用本文所提出的算法,基于正常交通和堵塞交通对电动汽车快速充电站进行了规划。通过对结果的分析,表明本模型具有一定的可行性和参考性。
[Abstract]:Climate, energy and environment are the main problems that human society faces together. With the worsening of environmental pollution and energy crisis, electric vehicles, as an effective means of solving the problem, have been widely agreed in the world. Whether the electric vehicle can develop rapidly and healthily, the reasonable and effective planning and construction of the corresponding charging facilities play a crucial role. This paper first introduces the three main types of electric vehicles, and briefly introduces their advantages and disadvantages. According to different technical means and operation methods, three feasible charging methods are pointed out, and the scope of use is given in combination with their respective requirements. Then, the basic charging facilities of electric vehicle are introduced in detail, and the mode of charging station used in this paper is put forward. In view of the unique spatial pattern of the trunk highway, the dynamic fluid model of the electric vehicle driving on the urban trunk road is established by applying the principle of conservation of traffic flow, combined with the characteristics of strong randomness and limited driving distance of the electric vehicle. This model can be used to calculate the density of electric vehicles travelling on the highway and the arrival rate of electric energy replenishment to reach the rapid charging station. According to the characteristics of charging service for electric vehicles, the theory of M/M/S queuing theory random service system is used to meet the demand of the number and power of the rapid charging piles of electric vehicles with stable charging station service. For the randomness of traffic flow, the expectation of each variable is used to satisfy the generality of the model. Finally, taking the driving law of a certain highway as an example, using the algorithm proposed in this paper, the rapid charging station of electric vehicle is planned based on normal traffic and congested traffic. The results show that the model is feasible and referential.
