DHEMOS is a simulation system developed for district heating systems, in which models for consumption, distribution and production are interconnected. The focus of this report has been to continue developing the models related to production analysis, and the specific goal of the study has been to develop the system towards production analysis and to evaluate methods relating to its operational use. The system has been adapted to handle financial and environmental parameters related to operational production planning. Functionality to handle load forecasts have been evaluated and included into the system. The study has been performed in collaboration with Swedavia who owns and runs Landvetter Airport. The district heating system at Landvetter Airport has been the base for all simulation experiments within this study. The process to calibrate and adjust DHEMOS is described and a number of scenarios are evaluated in order to find optimal operational situations with the help of active load control. The results show that DHEMOS is a competent tool for operational production planning. By combining the ability to perform load forecasts with practical usability the system can be used as a support tool when finding optimal operational strategies in relation to financial, technical and environmental variables.
