Abstract: Simulation techniques are regularly used by district heating companies as a support system when optimizing and improving the operational and strategic functionality within a district heating system. Normally the simulation models regarding production, distribution and consumption are handled separately, but there are several benefits to be found by combining these models. HEMOS is a simulation tool based on open source software which aims to join different simulation models in order to achieve such a system-wide overview. This simulation tool has been developed as part of previous research and has been used within several earlier projects as a support tool for new technologies. The purpose of this pre-study is first and foremost to:
* evaluate the current status and capacity of DHEMOS
* carry out a comparison between existing commercial simulation systems and DHEMOS
* evaluate the future potential of DHEMOS and estimate the amount of work needed in order to make the system a mature and usable simulation tool for trade, research and learning.
The results from this study show that DHEMOS has a basic ability to ”compute correctly”, even though the present system lacks important functionality without which it cannot fully compete with commercial alternatives. However, DHEMOS does display a number of fundamental design characteristics which shows that the system has a legitimate potential for the future. This pre-study has been a collaboration between Blekinge Institute of Technology
and Göteborg Energi. Simulation results from the district heating network in Ale i Gothenburg has been used when comparing the systems.
Summary in Swedish: Detta är en förstudie som har som syfte att jämföra simuleringsverktyget DHEMOS med andra på marknaden förekommande kommersiella verktyg. DHEMOS baseras på öppen källkod och har utvecklats i samband med tidigare forskning.
