Identification method and device for power flow blocking of power system, and electronic equipment

The invention provides a power flow blocking identification method and device of a power system and electronic equipment. The method comprises the following steps: acquiring a first auxiliary variable of a generator set of the power system, acquiring a second auxiliary variable of a node load of the power system, acquiring a third auxiliary variable of a transmission line of the power system, and acquiring a fourth auxiliary variable of a power grid stable section of the power system; determining a constraint condition combination at least according to the first constraint condition, the second constraint condition, the third constraint condition and the fourth constraint condition; and constructing an objective function according to the first auxiliary variable, the second auxiliary variable, the third auxiliary variable and the fourth auxiliary variable, determining the minimum value of the objective function under the condition of meeting the constraint condition combination, determining the position of po
