摘要
在能源转型和科技进步的推动下,高比例可再生能源和高比例电力电子设备(即"双高")正成为电力系统发展的重要趋势和关键特征,电力系统的动态行为随之发生重大变化,产生了新的稳定性问题。该文从分析"双高"电力系统的特点出发,先概述"双高"对经典稳定性各个侧面的影响,然后简要归纳"双高"背景下的新型稳定性问题,进一步探讨IEEE经典和扩展稳定性分类的适用性,最后尝试提出一种新的分类方法和框架,在维持经典分类逻辑的同时,兼容新的"双高"场景,希望有利于推动"双高"电力系统稳定性建模、分析与控制研究。
Driven by energy transition and technological progress, power system industry is undergoing a rapid development with an important trend or key feature, i.e., high penetration of renewable energy plus high penetration of power electronic equipment(namely, "double high"), which, however, brings significant changes to the dynamic behavior of the system and causes new issues of stability. In this paper, the new features of "double high" power systems were summarized first. Next, their impacts on the various aspects of classical power system stability were briefly reviewed. Then, we surveyed the emerging stability issues in the context of "double high". After an examination of applicability of the classical and extended classification of power system stability by IEEE/Cigre, a new classification framework was finally proposed to get with the new scenario of "double high", while maintaining the classical logic of classification. Hopefully, this work helps to promote the researches on modeling, analysis and control of the stability of "double high" power systems.
