Disaster Prevention Network Planning Method Based on Disaster Map

Abstract

This paper mainly studies the problem of network planning in distribution network planning. Based on the research on distribution network planning problems, this paper proposes a distribution network planning method based on disaster map, solving the problem of introducing intermediate nodes into the planning and optimizing in feasible areas which was not considered in the previous research. Firstly, this paper establishes a mathematical model of distribution network planning considering the disaster risk of the area where the network is located, then checks the disaster prevention construction cost of the network on disaster map, finally solves the problem by using the simulated annealing algorithm, and it generates the optimal network structure and determines the constraint conditions. Finally, verifies the performance and effectiveness of the algorithm by an example analysis. The method proposed in this paper breaks through the bottleneck of searching the optimal solution within the limited point set by the traditional distribution network planning method, which makes the distribution network planning method more flexible and expands the selection of intermediate nodes. It also increases the probability of searching for a global optimal solution and provides a new idea for the distribution network planning.
