New Generation Algorithms for Determining of Optimal Parameters of Heating Systems

Determination optimal parameters of heating systems suggests finding a solution that provides the best network capacity by replacing pipelines and installing (modernization) pumping stations. In this case we normally solve a complex nonlinear programming problem with discrete and continuous variables. ESI SB RAS proposed effective methods to solve it. A method based on dynamic programming was devised for a treelike network. For ring-shaped networks, there is a multi-loop optimization method which is based on the principle of successive improvement of the solution. An important feature of these methods lies in the fact that they make it possible to fully consider the properties of complex mathematical models that define specific features of the applied equipment, methods for its installation and operation. The paper presents the results of further development of methods for solving a complex problem of determining optimal parameters of heating systems. A modified method and algorithms for determining of optimal parameters of heating systems are proposed. The proposed method and algorithms implemented in the SOSNA software are applied to solve the problems of optimal reconstruction of heating systems in cities and populated areas.
