A Review of District Heating Systems: Modeling and Optimization
The ever-increasing demand for heating in different sectors, along with more preventative regulations on greenhouse emissions, has forced different countries to seek new alternatives to heat buildings such as district heating system (DHS). Although rudiments of DHSs can be observed over the centuries, it was not widely implemented until last two decades when the DHS became a strategy to design ...
متن کاملMethod of Evaluation of Efficiency Improvement Potential for District Heating Systems with Focus on Variable Speed Centrifugal Pumps
The goal of this research is the derivation of method for evaluation of efficiency improvement potential for district heating systems with focus on variable speed centrifugal pump. The effectiveness of the usage of the proportional pressure control is compared with the constant pressure control. This is why, energy calculation analyses have been realized for variable speed centrifugal pumps, an...
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...
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...
