【摘要】：随着全球能源资源与气候情况的日渐严峻,环保、节能的电动汽车是未来汽车发展的趋势,各类型充电站的建设也逐渐成为制约世界各国电动汽车发展的重要因素。与传统充电站相比,以光伏充电站为代表的新能源充电站虽然加大对可再生能源的直接利用,具有一定节能环保的意义,但其在经济效益方面并无明显优势,因而未得到足够发展。为了实现电动汽车光伏充电站的利益最大化,本文利用车网互联模式,令电动汽车光伏充电站可与电网更紧密的相连,既可实现可再生能源的有效利用,更能维持电网功率平衡,使用户获得更大的经济效益。首先,对电动汽车充电站的分类结构等进行了系统的研究:其次,对电动汽车光伏充电站结构及主要组件功能进行分析,并对其运营收入来源进行分析;在车网互联模式的基础上,对不同种类电动汽车的行为特性进行分析;最后建立电动汽车光伏充电站运行模型,对电动汽车参与车网互联的经济性进行分析,得出在不同模式下充电站的运行策略,并以调峰模式下充电站对电网调峰容量与充电站收益的提升效果为目标进行仿真计算。本文所建模型可以提前判断电动汽车光伏充电站所采用的运行模式,并可根据实际情况灵活调整。本文对电动汽车光伏充电站的充放电能量管理及经济效益提供了一定的理论基础。
[Abstract]:With the increasingly severe global energy resources and climate situation, environmental protection, energy saving electric vehicles are the future trend of automobile development. The construction of various types of charging stations has gradually become an important factor restricting the development of electric vehicles around the world. Compared with the traditional charging stations, the new energy charging stations, represented by photovoltaic charging stations, increase the direct use of renewable energy. It has the meaning of saving energy and environmental protection, but it has no obvious advantage in economic benefit, so it has not got enough development. In order to realize the maximum benefit of photovoltaic charging station of electric vehicle, this paper uses the car network interconnection mode, in order to realize the maximum benefit of photovoltaic charging station of electric vehicle. The photovoltaic charging stations of electric vehicles can be more closely connected to the power grid, which can realize the efficient use of renewable energy, maintain the power balance of the power grid, and achieve greater economic benefits for users. The classification structure of charging station of electric vehicle is studied systematically. Secondly, the structure and main component function of photovoltaic charging station of electric vehicle are analyzed, and the source of operating income is analyzed. The behavior characteristics of different kinds of electric vehicles are analyzed. Finally, the operation model of photovoltaic charging station of electric vehicle is established, and the economy of participating in network interconnection of electric vehicle is analyzed, and the operation strategy of charging station in different modes is obtained. The aim of this paper is to simulate the effect of peak shaving capacity and revenue of charging station in peak-shaving mode. The model in this paper can judge the operation mode of photovoltaic charging station of electric vehicle in advance. This paper provides a theoretical basis for charge and discharge energy management and economic benefit of photovoltaic charging station of electric vehicle.
