电动汽车低渗透率下的供能模式及供能设施的LCC最优规划

Energy supply schemes for low penetration of electric vehicles and optimal planning for energy supply facilities based on LCC

提出了我国现阶段电动汽车低渗透率下的供能模式,并以此为依据建立了基于全寿命周期成本(LCC)的供能设施最优规划模型。将充电模式和换电模式进行有效的结合,对不同类型的车辆采用与其行驶特点相适应的供能方式,由此提出综合了集中充换电站、配送站和快速充电站的供能设施规划原则,并引入LCC理论建立相应的最优规划模型。结合伏罗诺伊图和仿电磁学算法对模型求解。通过算例分析验证了此方法能得到综合了经济性、可靠性和持续性等多目标的最优规划方案。

The energy supply schemes for low penetration of electric vehicles at this stage in China are presented, and based on this the optimum planning model of energy supply facilities based on the life cycle cost theory is established. With the combination of charging pattern and battery swap pattern, different types of vehicles take use of different ways that adapt to their driving characteristics. The planning principle of energy supply facilities including center station, swap station and fast charging station is proposed, and corresponding optimum planning model is set up based on LCC. This model is solved by combining Voronoi diagram with electromagnetism-like mechanism. A numerical example verifies that this method can get optimal planning program which integrates multiple objectives like economy, reliability and continuity.
