Synergistic Engineering of Amorphous Cathode and Hybrid Electrolyte Toward Stable High‐Voltage Aqueous Zn‐Ion Batteries

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT The development of high‐voltage aqueous zinc‐ion batteries (AZIBs) is primarily hindered by the lack of suitable cathode materials and electrolytes that can work in broad voltage windows. Herein, we propose a synergistic strategy that concurrently addresses these challenges through the integration of an amorphous vanadium oxyphosphate/graphene

The game of energy transition: A game theoretical perspective on public participation procedures in infrastructure planning

open access: yesEuropean Policy Analysis, Volume 10, Issue 1, Page 39-60, Winter 2024.
Abstract For energy transition, infrastructure construction is often indispensable but also contested and potentially problematic for social cohesion. Through a game theoretical lens, we examine the basic configuration of infrastructure conflicts. Informed by the empirical example of German electricity grid planning, we discuss three approaches to ...

分布式光伏接入对配网系统的暂态特性影响研究

open access: yesDianci bileiqi, 2023
随着大量分布式光伏接入配电网,电力系统负荷侧的动态特性产生显著变化,尤其是配电网发生故障时,光伏的有功和无功响应对配网产生较大影响,因此,需要对分布式光伏接入对配网系统的暂态特性进行建模分析。基于光伏并网系统传统结构及控制方式,提出分别适用于低电压和高电压故障下,有功与无功解耦的逆变器保护控制策略,并对模型的高低电压穿越能力进行仿真,并基于逆变器实际电压穿越检测报告进行检验,验证了该光伏并网系统模型具备规定的故障穿越能力。由北京地区某光伏电站实际配网结构、设备参数和光伏控制参数 ...
