Abstract:In order to enhance the ability of distribution network to withstand typhoon disaster, a two-stage optimal dispatching model was proposed. In the pre-disaster stage, the probability model of line failure caused by typhoon disaster is constructed according to the predicted typhoon moving path, and Monte Carlo method is used to simulate the fault state of distribution network lines. In order to minimize the pre-layout cost and load reduction risk cost of mobile energy storage vehicles, the pre-layout location of mobile energy storage vehicles is optimized. In the post-disaster stage, the access location and charging and discharging time sequence of mobile energy storage vehicles are dynamically scheduled to minimize load reduction costs during line failures. The effectiveness of the proposed model is verified by the improved IEEE33-node system, and the results show that the model can significantly improve the toughness of the distribution network in the case of typhoon disasters.
