Calibration of Pipe Networks for District Heating using the Nonlinear Optimisation Method

摘要

In this article a method for developing an optimal tree path of a heating system is proposed. Based on the simplex optimisation method, the mathematical model, consisting of the non-linear objective function and the system of non-linear equations for the hydraulic limitations, is solved by a computer programme. The investment and running expenses are evaluated by a capitalised value method. The optimisation of the district heating system with 24 nodes and 33 pipe sectors is processed on a real network case study.
