Intelligent adjustment method and system for power transmission section in power utilization system

The invention relates to the technical field of power systems, and particularly provides an intelligent adjustment method and system for a power transmission section in a power utilization system, and the method comprises the steps: obtaining an overload line set L in the power utilization system; calculating a positive comprehensive sensitivity index # imgabs0 # and a negative comprehensive sensitivity index # imgabs1 # of nodes in the power utilization system to the overload line set L, and removing nodes of which the positive comprehensive sensitivity index is smaller than a preset value and the absolute value of the negative comprehensive sensitivity index is also smaller than the preset value to obtain a filtering node set N; and constructing a power flow regulation and control model based on a Cplex solver, and calculating to obtain the output adjustment amount of the nodes in the filtering node set N by taking the minimum total output adjustment amount of the nodes as a target.
