Abstract: By introducing the viewpoint of interruptible load of DSM into N-1 static security analysis of the power grid section transmission capacity, this paper proposes a mathematical model of power grid section transmission limit under the constraints of traditional N-1 static security. Broaden the conditions of traditional N-1 analysis through using the interruptible load management in receiving areas, an improved power grid section transmission limit model considering the interruptible load and power flow constraints is established. The opposite-quantities-adjusted in pairs method based on branch sensitivity is studied, and the adjustment table for reference and adjustment active power is given in detail. With above steps, the quantitative relationship between the increments of the grid section transmission limit and the load interrupted quantities is obtained. The IEEE39–bus testing system in BPA shows that the application of interruptible load can improve the grid section transmission limit, as well as improving the operation economy while guaranteeing the security of the power system.
