The article presents a new effective algorithm for the multi-loop optimiza- tion method, which allows us to solve the problem of determining optimal parameters for systems with a loop configuration. The new algorithm makes it possible to overcome the difficulties associated with their large dimension by hierarchical decomposition of the heat network model. The problem un- der consideration is to find the optimal diameters of pipelines, the parame- ters of pumping stations and the optimal flow distribution in the network. Thus, Energy Systems Institute SB RAS has developed the multi-loop opti- mization method based on the principle of step-by-step improving the solu- tion. An important advantage of this method is that it allows us to flexibly customize the computational procedure to the peculiarities of the simulated system.
Real heat supply systems usually have a hierarchical construction and con- sist of networks that have a loop part and tree branches. This feature of heat supply system construction has been used in development of a new algo- rithm for the multi-loop optimization method, which significantly reduces the number of calculations and counting duration without losing the accu- racy of the obtained results.
