Research on thermal optimal operation scheduling of multi-heat source Co-heating system

Multi-heat source co-heating networks have become the main trend of future development. However, the research for the thermal optimization and dispatch of multi-heat source co-heating networks is quite few in our country. In this paper, the general process of the optimal dispatch for multi-heat source co-heating systems is proposed, and the mathematical model for optimal thermal dispatch of multi-heat source co-heating systems is established. In addition, formulas and parameter selection method for the typical thermal schemes were given. By taking an actually heating network as an example, procedure and method for some thermal dispatch schemes are provided, and the optimal operating scheme based on technical and economic analysis is given. The method provided in this paper may supply the theoretical basis for operation scheduling of realistic engineering heating network. It is very meaningful for saving energy and improving environment.
