Linear programming optimization of heat distribution in a district-heating system by valve adjustments and substation retrofit

摘要: Abstract The unbalanced distribution of heat in a district-heating system may be caused by the increase hydraulic resistance pipe network, decrease transmittance radiators inside buildings, and building envelope. This situation yields overheating some buildings underheating other buildings. A is analyzed that consists plant, primary substation, secondary three steady-state, bottom-up approach sequential linear programming used to solve this optimization problem. Results show significant improvement thermal comfort reached adjusting valves network resizing substation exchanger.
