Thermo - hydraulic simulation of district heating networks
Current developments of the European energy markets are influencing the operation strategy of heat suppliers. Especially providers of district heating systems fed by conventional heat production (i.e. CHP) have to react with appropriate measures to these changes. The integration of thermal storages, decentralization of the heat production, changing heating technologies or adjusting the temperat...
متن کاملTemperature Prediction in District Heating Systems with cFIR models
Current methodologies for the optimal operation of district heating systems are based on model predictive control. In complement to load forecasts, accurate predictions (up to 12-hour ahead) of the water temperature at critical points of the networks are crucial for meeting constraints related to consumers while minimizing the production costs for the heat supplier. The paper introduces a new f...
متن کاملSimulation Models to Size and Retrofit District Heating Systems
District heating networks are considered as convenient systems to supply heat to consumers while reducing CO2 emissions and increasing renewable energies use. However, to make them as profitable as possible, they have to be developed, operated and sized carefully. In order to cope with these objectives, simulation tools are required to analyze several configuration schemes and control methods. ...
متن کاملMulti-Agent Systems for District Heating Management.book
i This thesis investigates the applicability of multi-agent systems as a control approach for district heating systems. The consumers, i.e., the heat exchange systems, in current district heating systems are purely reactive devices and have typically no communication capabilities. They are only able to make local decisions without taking into account the global situation in the system. In this ...
متن کاملThermal Transients in District Heating Systems
Heat fluxes in a district heating pipeline systems need to be controlled on the scale from minutes to an hour to adjust to evolving demand. There are two principal ways to control the heat flux keep temperature fixed but adjust velocity of the carrier (typically water) or keep the velocity flow steady but then adjust temperature at the heat producing source (heat plant). We study the latter sce...
