| 摘要: |
| 综述电力系统柔性和弹性的研究进展，指出“柔性”侧重于描述电力系统灵活可调的能力，“弹性”侧重于描述电力系统抗击极端事件的能力。随着电力系统中持续性的随机扰动不断增加，“柔性”和“弹性”均不能描述电力系统耐受持续随机扰动的能力，为此，提出“电力系统韧性”的概念，即电力系统在持续的随机扰动之下不发生崩溃、解列而保持正常运行的能力，并给出电力系统韧性的研究内容和技术路线，包括描述模型、分析方法、评价指标和提升途径等。 |

| Abstract: |
| The research progress of power system flexibility and resilience is reviewed, it is pointed out that “flexibility” emphasizes on describing the flexibility and adjustability of power system, while “resilience” emphasizes on describing the ability of power system to resist extreme events. Along with the continuous increase of persistent stochastic disturbances in power system,“flexibility” and “resilience” neither can describe the tolerance ability of power system to persistent stochastic disturbances, for which, the concept of “power system toughness” is proposed, i. e. the ability of power system to maintain normal operation without collapse or disconnection under persistent stochastic disturbances, and the research contents and technical routes are given, including description models, analysis methods, evaluation indexes, promotion ways and so on. |
