English: With the advancement of the global energy transition and the proposal of carbon neutrality goals in the transportation sector, transportation electrification has become one of the key pathways toward green and low-carbon development. The large-scale integration of electric vehicles (EVs) and rail transit systems has not only significantly altered the energy consumption structure of transportation but also brought new challenges and opportunities for the operation, dispatch, and planning of power systems. The high volatility and uncertainty of electrified transportation loads impose pressure on the grid while simultaneously creating opportunities for demand response, energy management, and the coordinated development of distributed energy systems. Therefore, there is an urgent need to establish accurate and efficient modeling methods to assess and optimize the impact of transportation electrification on power systems, promoting the deep integration and synergistic development of transportation and electricity networks.

中文: 随着全球能源转型的推进和交通领域碳中和目标的提出，交通电气化成为实现绿色低碳发展的关键路径之一。大规模电动汽车（EV）及轨道交通系统的接入不仅显著改变了交通能源消费结构，也对电力系统的运行、调度与规划带来了新的挑战与机遇。电动交通负荷的高波动性和不确定性使得电网面临压力，同时也为需求响应、能源管理和分布式能源系统的协同发展提供了契机。因此，亟需建立准确高效的建模方法，以评估和优化交通电气化对电网的影响，推动交通与电力系统的深度融合发展。
