新能源发电经直流送出成为碳达峰、碳中和战略背景下新能源大基地、规模化开发利用的主导形式之一。在高压直流输电送端已初步形成高比例新能源、高比例电力电子的局部双高电力系统。与以同步发电机为主导的传统电力系统相比,系统运行特性发生了深刻变化,逐渐出现宽频振荡和暂态过电压等新型稳定问题,导致大规模新能源脱网事故频发,传统电力系统的分析方法和设计原则面临挑战。本文针对双高电力系统的特性认知、作用机理、分析方法、研究手段、工程应用开展研究,明确宽频振荡和暂态过电压产生机理,提出小信号阻抗分析方法和电磁暂态仿真研究手段相结合的技术路线,研究成果已在我国华北、西北和东北地区新能源基地经直流送出重大工程中得到验证。最后,针对未来建设以新能源为主体的新型电力系统给出思考与建议。
Recent advances toward high voltage, EC-free electrolytes for graphite-based Li-ion battery

Lithium-ion batteries are a key technology in today’s world and improving their performances requires, in many cases, the use of cathodes operating above the anodic stability of state-of-the-art electrolytes based on ethylene carbonate (EC) mixtures. EC, however, is a crucial component of electrolytes, due to its excellent ability to allow graphite anode operation–also required for high energy density batteries–by stabilizing the electrode/electrolyte interface. In the last years, many alternative electrolytes, aiming at allowing high voltage battery operation, have been proposed. However, often, graphite electrode operation is not well demonstrated in these electrolytes. Thus, we review here the high voltage, EC-free alternative electrolytes, focusing on those allowing the steady operation of graphite anodes. This review covers electrolyte compositions, with the widespread use of additives, the change in main lithium salt, the effect of anion (or Li salt) concentration, but also reports on graphite protection strategies, by coatings or artificial solid electrolyte interphase (SEI) or by use of water-soluble binder for electrode processing as these can also enable the use of graphite in electrolytes with suboptimal intrinsic SEI formation ability.
