全球能源互联网, 2020 网对网式的国与国之间的电力协商交易模式无法全面支撑各类跨国电力交易，严重依赖运营机构信用和成员互信的跨国电力市场也不容易形成，区块链技术有可能提供一种介于以上两种方式之间的跨国电力交易模式。从跨国电力交易的实际需求出发，分析了区块链技术的适用性，建立了一个包含半分布式网络拓扑结构、多主体交易区块链数据结构和多管理节点共识机制的基于联盟链的跨国电力交易框架，并设计了详细的跨国电力集中交易过程，分析了模型与数据共享、安全约束出清等关键支撑技术。研究表明，区块链技术对于跨国电力集中交易有很高的适用性 ...

, 2023 张北可再生能源柔性直流电网工程投运以来，交直流系统中数次出现次、超同步振荡问题。对2022年某日振荡发生时现场录波采集到的交直流振荡波形数据进行分析，录波数据分析表明，交流侧的次同步（43.75 Hz）、超同步（56.25 Hz）振荡，在dq坐标系下均表现为6.25 Hz振荡，同时在直流电压和直流电流中也出现了6.25 Hz的振荡频率。初步判断振荡发生的原因是：风电场功率快速变化时，站间骤然变化的直流电压引起了直流电流发生振荡，直流电流通过直流通路造成MMC子模块电容电压产生振荡 ...

New Phytologist, Volume 247, Issue 2, Page 504-517, July 2025.Summary Repetitive DNA is a feature of all organisms, ranging from archaea and plants to humans. DNA repeats can be seen both in coding and in noncoding regions of the genome. Due to the recurring nature of the sequences, simple DNA repeats tend to be more prone to errors during replication and repair, resulting in variability in their unit length ...
