САЖЕТАК / ABSTRACT:
District heating systems provide centralised heat generation and efficient distribution in urban environments, enhancing energy efficiency and mitigating local uncontrolled emissions. Nonetheless, district heating is influenced heavily by fluctuations in energy prices, environmental and climate issues, and the necessity of maintaining reliable operations during the heating season. These systems often depend on continuously functioning equipment to meet fundamental heating requirements, while peak demands are addressed with supplementary flexible heat sources. This frequently results in system oversizing, elevating operating expenses and inefficiencies. An effective strategy to mitigate peak demand challenges is heat consumption shifting, which reallocates energy usage more uniformly over the day. Shifting heat demand from peak hours to times of lesser consumption enhances overall system efficiency and diminishes the necessity for extra peak-load capacity. This method can be very advantageous in current district heating networks without necessitating significant infrastructure modifications.
A simulation of heat load shifting was performed on the district heating system of the City of Maribor. The research employed altered heat consumption patterns to examine the viability of load shifting and its effects on system performance. The results indicate that optimised energy distribution may augment operational stability.
