Abstract：
This study presents a simulation-based optimization method for operational strategies of sewage-source heat pump systems. Firstly, a system simulation model is developed, with key parameters calibrated using operational data. Subsequently, controllable variables are selected as optimization parameters based on system characteristics, and the GenOpt-Dymola co-simulation approach is employed to optimize heating system operations. Case study results demonstrate that this method effectively reduces energy consumption while maintaining thermal comfort, achieving a 10.23% reduction in total operational energy consumption during the heating season.
