control strategy. Through the study of the primary system and secondary system in DH systems, dynamic models of the DH network … in the process of solving the dynamic models. Peak-valley method was introduced to find the actual lag time, and the … calculating data of the two parameters verified the correctness of the dynamic models. The lag time is proved to be approximately …
