Methodological provisions to the formation of district-distributed heating systems

The main methodological principles for the transformation of district heating systems into ones of a district-distributed type, optimally combining distributed (decentralized) and district (centralized) areas, are proposed, based on a comprehensive solution of problems of assessing the economic efficiency and reliability of heating to consumers. Wherein, the distributed sector is formed based on a prosumer that has its own generation, covering part of its own heat load and providing an additional functional and time redundancy for the system. As a result, сonclusions and directions for further research are formulated.
