Abstract

One of the most remarkable features of power and energy systems pertains to their extremely far-reaching scales, which are unique in the field of engineering. In continental Europe, for example, the synchronous ac power system integrates capitals from Lisbon to Warsaw and from Athens to Copenhagen. Reaching farther out to the north, high-voltage dc (HVdc) links connect to Sweden and the United Kingdom. And as in other regions of the world, those grids are being further developed to integrate more renewables. This only adds to the diversity of technologies in the power grids and contributes to the wide range of timescales involved. Those range from electrothermal interactions in the range of minutes over electromechanical transients within seconds, down to microseconds or even faster for the electromagnetic transients of traveling waves.

用移频连接尺度：电力系统多尺度瞬态的频率自适应模拟

电力和能源系统最显著的特征之一是其极其深远的规模，这在工程领域是独一无二的。例如，在欧洲大陆，同步交流电力系统整合了从里斯本到华沙、从雅典到哥本哈根的首都。在更远的北部，高压直流(HVdc)线路连接到瑞典和英国。与世界其他地区一样，这些电网正在进一步发展，以整合更多的可再生能源。这只会增加电网技术的多样性，并导致所涉及的时间范围很广。这些范围从几分钟内的电热相互作用到几秒钟内的机电瞬变，到微秒甚至更快的行波的电磁瞬变。

期刊介绍： IEEE Electrification Magazine is dedicated to disseminating information on all matters related to microgrids onboard electric vehicles, ships, trains, planes, and off-grid applications. Microgrids refer to an electric network in a car, a ship, a plane or an electric train, which has a limited number of sources and multiple loads. Off-grid applications include small scale electricity supply in areas away from high voltage power networks. Feature articles focus on advanced concepts, technologies, and practices associated with all aspects of electrification in the transportation and off-grid sectors from a technical perspective in synergy with nontechnical areas such as business, environmental, and social concerns.
