The Dijkstra algorithm is firstly used to the partition of the power grid, the contact line between regions as the initial section, according to the OTDF, the distribution coefficient and the flow direction of the transmission section are organized from the initial section. In the calculation of the thermal stability limits of transmission section, the power sensitivity matrix based on the generator output power control circuit, maximum power in section under normal operation can transfer as objective function, the section of each line followed by the target on line, the output of generator as control variables, to meet the whole network line thermal stability constraint and the generator, through the optimization method to get off the chickens. At the same time, the maximum transmission power limit of each target line is obtained, and the minimum value of the transmission limit of each target line is taken as the transmission limit of section, so that the critical section is obtained. The effectiveness of the proposed method is verified in the IEEE39 node system.
