Abstract

Održavanje kontinuiteta rada kritične infrastrukture, kao što su izolirane crpne stanice za vodoopskrbu, zahtijeva robusna rješenja za pomoćno napajanje. Sustavi neprekidnog napajanja (UPS) obično koriste baterijske sustave za pohranu energije (BESS), koji, osim što osiguravaju pričuvno napajanje, omogućuju energetsku arbitražu kako bi se smanjili troškovi električne energije iz mreže. Ovaj Završni rad ispituje izvedivost komercijalno dostupnog BESS-a za povećanje autonomije rada vodocrpne stanice opremljene glavnim elektromotornim pogonom pumpe nazivne snage 350 kW. Koristeći povijesne podatke o potrošnji komunalne vode za Cresko-Lošinjsko otočje, dobivene iz javno dostupnih izvora, provedene su simulacije za modeliranje rada crpnih stanica sa i bez integracije BESS-a tijekom kontinuiranog rada. Dobiveni podaci pružaju sveobuhvatnu analizu potencijalnih ušteda energije, smanjenja troškova i procijenjenog povrata ulaganja (ROI).

Abstract (english)

Maintaining the continuity of critical infrastructure, such as isolated water pumping stations, requires robust backup power solutions. Uninterruptible power supply (UPS) systems typically use battery energy storage systems (BESS), which, in addition to providing backup power, enable energy arbitrage to reduce electricity costs. This thesis examines the feasibility of a commercially available BESS to increase the autonomy of a water pumping station equipped with a main electric motor pump drive with a nominal power of 350 kW. Using historical data on municipal water consumption for the Cres-Lošinj archipelago, obtained from publicly available sources, simulations were conducted to model the operation of pumping stations with and without BESS integration during continuous operation. The obtained data provide a comprehensive analysis of potential energy savings, cost reductions, and estimated return on investment (ROI).
