摘要:

为了实现交通系统的电气化,重要的是理解电网储能、太阳能光伏系统和控制策略等技术如何助力电动汽车充电的大规模部署。在本研究中,我们提出了 EV-EcoSim,这是一个协同仿真平台,它将电动汽车充电、电池系统、太阳能光伏系统、电网变压器、控制策略和配电系统耦合在一起,以进行成本量化并分析电动汽车充电对电网的影响。这个基于 python 的平台可以运行用于实时操作的滚动时域控制方案和用于规划问题的一次性控制方案,并具备不同系统的多时间尺度动态以模拟真实场景。我们通过一个案例研究展示了 EV-EcoSim 的实用性,该研究侧重于电池容量的经济评估,以在考虑快速充电对配电网影响的同时降低电力成本。我们以表格形式呈现了对电池容量的定性和定量评估。表格结果描绘了候选电池容量解决方案之间的权衡,为不确定性下的决策提供了全面见解。此外,我们展示了电池控制器模型保真度对系统成本的影响,并表明电池控制器的保真度可以完全改变规划电动汽车充电站点时做出的决策。

英文摘要:

To enable the electrification of transportation systems, it is important to understand how technologies such as grid storage, solar photovoltaic systems, and control strategies can aid the deployment of electric vehicle charging at scale. In this work, we present EV-EcoSim, a co-simulation platform that couples electric vehicle charging, battery systems, solar photovoltaic systems, grid transformers, control strategies, and power distribution systems, to perform cost quantification and analyze the impacts of electric vehicle charging on the grid. This python-based platform can run a receding horizon control scheme for real-time operation and a one-shot control scheme for planning problems, with multi-timescale dynamics for different systems to simulate realistic scenarios. We demonstrate the utility of EV-EcoSim through a case study focused on economic evaluation of battery size to reduce electricity costs while considering impacts of fast charging on the power distribution grid. We present qualitative and quantitative evaluations on the battery size in tabulated results. The tabulated results delineate the trade-offs between candidate battery sizing solutions, providing comprehensive insights for decision-making under uncertainty. Additionally, we demonstrate the implications of the battery controller model fidelity on the system costs and show that the fidelity of the battery controller can completely change decisions made when planning an electric vehicle charging site.
