Transient stability control of power system is a non-linear optimization problem which contains many constraints. Considering the cost of preventive control, emergency control and the following restorative control synthetically, a model of preventive control and emergency control based on DSR(Dynamic Security Region) and probabilistic insecurity measurement is proposed in the paper, and the optimal operating point of the system was obtained by using the improved genetic algorithm. In the end, the feasibility of the model and optimization strategy are verified by the case of the IEEE 4-generators 11-nodes system. Simulation show that the cost of comprehensive control of prevention and emergency is 13.2% less than the case that without the consideration of the random factors of the fault.
