摘要
Abstract
Taking the minimum annual cost value of the heating network as the optimization objective,a mathematical model for pipediameter optimization of heating networks was established.The particle swarm optimization(PSO)algorithm was adopted to solve the model.Pipe diameters were initialized using three strat-egies:the all-random initialization strategy(All Ran-dom),the initialization strategy with recommended pipe diameter(Delta),and the initialization strategy with both recommended pipe diameter and topological structure(Tree).A typical branched heating network was selected as a calculation example to verify the fea-sibility and practical performance of the three initial-ization strategies.Comparison of PSO optimization results based on the three initialization strategies indi-cates that the results using the Delta and Tree strate-gies outperform those using the All Random strategy.The Tree+PSO algorithm shows the fastest conver-gence,the lowest annual heating network cost,and demonstrates significant advantages in both optimiza-tion accuracy and convergence efficiency,making it the preferred solution for pipediameter optimization of heating networks.关键词
