Abstract

This study aims to maximize the comprehensive economic benefits of heat storage in the pipe network of a central heating system, and establishes a bi-level optimization model for the pipe network topology reconstruction scheme. The case optimization results show that after the pipe network topology reconstruction, the total volume of high-temperature heat medium in the return water pipe network can reach 2217-4185 m³, accounting for 34%-65% of the total volume, which significantly improves the heat storage capacity of the heating pipe network. Considering both the heat storage benefits and construction costs comprehensively, the optimal number of bypass branch configurations for the case is 9, and the comprehensive economic benefits of the project reach 2.6866 million yuan.
