Rare Metals, Volume 45, Issue 6, June 2026.ABSTRACT Platinum (Pt) single‐atom catalyst (SAC) shows great promise for hydrogen evolution reaction (HER), but faces a huge challenge in activity enhancement due to the isolated single‐atom sites. Fabricating support with partially amorphous (pa) structures to realize the synergetic interaction in neighboring single atoms could facilitate H2O ...

全球能源互联网, 2019 由于柔直电网“隔离”了频率信号，互联多区域协同调频问题亟待研究。现有研究大多利用换流站的下垂控制以及直流电压偏差实现频率信号的传递，但忽略了风电集群接入后由风电功率正常波动引起的直流电压偏差干扰，可能导致风电集群在无需调频时频繁地调整出力。对此，提出了基于直流电压偏差及其特征量的多区域协同调频策略，分别针对电网频率偏移和风电功率波动两种场景提取直流电压偏差特征量，包含电压变化量、电压变化率和滤波后的电压分量幅值3个特征，并基于二者的差异设置换流站启动下垂控制的判据。仿真结果验证了所提方法的有效性。
