The prevention-correction coordinated control of power system based on operational risk

In order to ensure the power system satisfying the security and stability constraints for different fault condition, we put forward the idea that the operational risk can be applied to the coordination problem for preventive control and corrective control. Therefore, a prevention-correction coordinated control model is established. In order to solve this model quickly, the bi-level programming model is used to decompose the proposed model. A mixed method, which applies the interior-point method into particle swarm optimization algorithm, is presented to solve the optimized model. Finally, through the comparative simulation on a six nodes test system between the proposed model and the traditional model, the rationality of the proposed model is verified.
