在环境保护的压力下,新能源和电动汽车越来越多地被引入电网,这就增加了电力系统的不确定因素.为此,首先讨论不确定环境下电力系统安全防御中的一些拓扑控制问题,然后给出这些问题的图论描述以及研究中面临的挑战和进展. Under the pressure of environmental protection, new energy and electric vehicles are more and more introduced into the grid, which increases the uncertainty of the power system.Therefore, some topology control in the power system security defense in uncertain environment is first discussed Problems, and then gives a graphical description of these problems and the challenges and progress in the research.
