Gaoya dianqi, 2020 文中在分析电动汽车充电负荷特征的基础之上,利用日行驶里程、起始充电时刻、充电功率、充电时长、初始荷电状态和电动汽车保有量这6个影响因素建立了电动汽车充电负荷的预测模型,并详细介绍了利用蒙特卡罗模拟算法求解该模型的步骤。在实例中将电动汽车分为私家车、公务车和出租车,根据其特点的不同分别进行负荷预测,最终得到该区域总的电动汽车充电负荷。最后基于蒙特卡罗模拟算法开发了电动汽车充电负荷预测系统,方便使用者准确计算。

Institutions, in time: Designing feedback pathways for shared infrastructure transitions
Policy Studies Journal, Volume 53, Issue 3, Page 654-680, August 2025.Abstract Electric utilities, challenged by a rapidly unfolding energy transition, use many informal institutions to bridge across technologies and sectors. Little is known, however, about how electric utility systems and other polycentric systems' institutions‐in‐use vary and evolve over time.

How Many Floods Have Occurred in China in the Past Decade? A Perspective From Social Media
Earth's Future, Volume 13, Issue 4, April 2025.Abstract Global climate change has led to frequent and widespread flood disasters in China. Traditional flood disaster investigations mainly focus on major flood events, and small‐scale flood events are often overlooked. This study utilized the Sina Weibo social media platform to detect flood events in 370 cities in China from 2012 to 2023.
