Abstract

The invention relates to a power distribution network disaster prevention backbone network frame planning method based on a Steiner tree model. The method comprises the following steps: firstly, on the basis of meeting the power supply of important users of a power distribution network under typical disaster conditions, establishing a Steiner tree model of a disaster prevention backbone network frame of the power distribution network based on network connectivity constraint and power flow constraint by taking the minimum construction cost and disaster risk of a line and a tower as an optimization target; and solving the optimization model by using a binary particle swarm algorithm to obtain an optimal backbone network frame scheme, and realizing power supply of the power grid to importantusers in disasters. According to the method, the comprehensive cost of carrying out differential transformation on the backbone network frame is considered, power supply of the power grid to importantloads during disasters is guaranteed, and the power supply self-guarantee capability of the power grid under the disasters is improved.

Description

Technical field [0001] The invention relates to the technical field of power systems, in particular to the technical field of distribution network planning, and specifically relates to a method for planning a disaster prevention backbone network frame of a distribution network based on a Steiner tree model. Background technique [0002] Large-scale blackouts of the power grid caused by severe weather and natural disasters occur frequently all over the world. Look for the backbone grid in the power grid, and differentiate the design of the backbone grid in the power grid, so that it can ensure the important The power supply of the load is an effective measure to improve the disaster resistance of the power grid. However, the current research on backbone grids is mainly aimed at the transmission grid. As the distribution network is connected to users and directly supplies power to users, how to enhance its disaster resilience should also be paid attention. [0003] At present, the r...
