摘要
运用直流潮流法,构建了电网弹性势能转移系数。电网弹性势能系数定量反映了不同线路对电网安全性的不同影响,可用于电网关键线路的识别。识别出关键线路后,需让关键线路对电网的影响更小,所以提出了电网N-1后映射弹性势能表达式,这样仅需知道电网N-1前的线路有功功率和线路参数就可快速判断是否优化成功,大大提高了判断速度,无需分别对电网不同线路N-1进行潮流计算再判断。
This article uses the DC power flow method to first construct the grid elastic potential energy transfer coefficient.The grid elastic potential energy coefficient quantitatively reflects the different impacts of different lines on the safety of the power grid,and can therefore be used to identify key lines in the power grid.After identifying the critical lines,it is necessary to minimize the impact of the critical lines on the power grid.Therefore,a flexible potential energy expression for the N-1 post-mapping of the power grid is proposed.This allows for quick determination of whether the optimization has been successful by only knowing the active power and line parameters of the lines before the N-1 of the power grid,greatly improving the speed of judgment without the need to separately perform power flow calculations on different lines of the power grid before N-1 and then make a judgment.
