Abstract: An active distribution network planning model and a solution strategy is proposed in this paper considering the multi-energy complementation. With consideration of the uncertainties and complementary characteristics of various renewable energy sources, typical scenarios are generated using the density-based clustering method, and an active distribution network planning model is build based on second order cone programming with the optimal cost-benefit of the distribution network as objective function. Considering that the distribution network planning in multi-energy complementary environment is a mixed integer nonlinear programming problem with a large number of scenarios, an efficient solution strategy is provided for the planning model based on the modern Benders decomposition algorithm under the framework of Branch-and-cut solution. In the end, the IEEE-24 node test system is used for case study, and the result has verified the validity of the planning model and the efficiency of the solution strategy.
