Combating district heating bottlenecks using load control

The 4th generation of district heating systems face a potential problem where lowered water temperatures lead to higher flow rates, which requires hydraulic capacity in terms pipe and pump sizes. This increases the effect already existing issue bottlenecks, causing peripheral units (customers) experience reduced rates. A coordinating control strategy is presented this work aimed at reducing such bottlenecks on comfort customers. done by distributing deficit over many rather than few. Previous works mainly focus MPC-structured controllers that depend complex system models online optimization techniques. proposes method little information about for individual minimal IT communication between systems. proposed compared with traditional an optimal baseline simulation study. shows can decrease worst case indoor temperature deviations.
