Research on distribution of power supply chain based on risk propagation model

The risk of a power network will bring huge social influence. To ensure the stable operation of transmission lines, the risk of the power network should be assessed and emergency supplies should be allocated to ensure the emergency needs. Based on the transmission network risk transmission model, this paper predicts the possible risk scale, takes the shortest emergency rescue time and minimum transmission network loss as the goal, and optimizes the distribution route of emergency rescue materials for transmission lines based on the NSGA-II algorithm. The distribution plan shows that the distribution of vehicle loads and travel distances is reasonable, which can complete the transportation of emergency supplies in the shortest time and at the lowest cost. Simulation results show that the improved NSGA-II algorithm can effectively solve the multi-objective distribution path optimization problem of emergency supplies.
