Gaoya dianqi, 2007 阐述了新型换流变压器及配套滤波装置的接线方案和滤波器设计特点,在此基础上建立了以初期投资最小为目标函数的滤波装置数学优化模型,在采用遗传算法对优化模型进行优化设计时,考虑到优化模型的特点,采用了混合罚函数法将有约束问题转化成带有罚项的无约束问题的目标函数。最后针对具体的新型高压直流输电平台模型给出了滤波装置优化设计的实例,算例结果验证了该优化设计的正确性。

Rare Metals, Volume 45, Issue 7, July 2026.ABSTRACT In electrocatalysis, traditional single‐atom catalysts (SACs) face challenges in achieving coordinated control of reaction pathways due to limitations such as single local energy levels and carrier recombination. By introducing an additional defect structure, it is possible to break the electronic structure symmetry, thereby activating SACs ...

Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT The development of lightweight, high‐attenuation, and broadband carbon‐based electromagnetic wave absorbers is hindered by the intrinsic trade‐off between impedance matching and dielectric dissipation. Herein, we report a facile and scalable synthesis of N‐doped lignin‐derived interconnected porous carbon (Nx‐LIPC) via hydrogen‐bond self ...

Gaoya dianqi, 2015 文中建立了风电场经两种拓扑结构的VSC-MTDC并入电网的模型,两种模型为串联模型和并联模型,并基于两种拓扑结构的比较结果对多端柔性直流输电控制器进行了优化。仿真模型主要包括:风电场等效聚合模型,风电场换流站控制器,直流电缆的Bergeron模型。优化方法采用单纯形算法。将两种拓扑结构的模型进行了仿真分析,仿真结果显示,在考虑到受交流系统扰动以及风电场侧切机情况下的稳定性,并联系统更加适合海上风电场经柔性直流输电并网。采用单纯形优化后的VSC-MTDC动态响应能力相对于优化改进前有了很大的提高。
