【摘要】：随着使用石油等化石燃料带来的环保方面问题的关注度的不断提高,全球发展清洁能源的要求愈加强烈,各国开始大力发展新能源汽车及其相关服务网络。电动汽车大规模的推广将带动相关充换电设施的发展,并对电网供用电、市场经济和节能减排策略等方面带来巨大的影响。本文首先介绍了电动汽车充电模式和换电模式,分析了不同模式下相适应的不同电动汽车用电情况和不同种类电动汽车充换电设施适用条件,得到适用于本文研究的充换电模式和布局规划充换电设施类别。建立以充电站年综合效益最大为目标函数,电动汽车用户换电需求和充电站容量为约束的综合优化数学模型,使用混合差分蜂群算法来对电动汽车集中充电站布局进行优化,并通过一个实际算例对本文提出的模型和算法的可行性和可靠性进行验证。最后考虑通过对电动汽车动力电池分时段集中充放电参与统一调度实现电网调峰,用实际数据对规模化的电动汽车参与电网调峰情况进行比较分析,结果表明规模化电动汽车参与电网调峰对降低电网负荷峰谷差,减轻电网压力有显著作用。
[Abstract]:With the increasing attention to environmental problems caused by the use of fossil fuels such as petroleum, the global demand for clean energy has become increasingly strong, and countries have begun to vigorously develop new energy vehicles and their related service networks. The large-scale promotion of electric vehicles will lead to the development of related charging and switching facilities, and will have a great impact on the power supply, market economy, energy saving and emission reduction strategy. In this paper, the charging mode and the changing mode of electric vehicle are introduced, and the different electric vehicle's electricity consumption and the applicable conditions of different electric vehicle's charging and changing facilities are analyzed. The types of charging and switching facilities suitable for the research in this paper are obtained. A comprehensive optimization mathematical model with the maximum annual comprehensive benefit of charging station as the objective function and the demand of electric vehicle users and the capacity of charging station as constraints is established. The hybrid differential swarm algorithm is used to optimize the layout of centralized charging stations for electric vehicles. A practical example is given to verify the feasibility and reliability of the proposed model and algorithm. Finally, the paper considers the realization of power grid peak shaving through centralized charge and discharge of electric vehicle power battery in different periods, and compares and analyzes the situation of large-scale electric vehicle participating in power grid peak regulation with actual data. The results show that the participation of large-scale electric vehicles in peak-shaving plays a significant role in reducing the peak and valley difference of load and reducing the pressure of power grid.
