Abstract

Optimalno nuđenje baterije temeljene na litij-ionskoj tehnologiji na energetskim tržištima u literaturi se najčešće modelira generičkim modelom spremnika energije. Međutim, litij-ionske baterije imaju specifičnosti u odnosu na ostale spremnike energije. U diplomskom radu se shodno tome istražuju precizni modeli baterija u literaturi, neki korišteni te neki eksperimentalni i implementira ih se u model optimalnog nuđenja te verificira na laboratorijskom postavu. Izračun efikasnosti takvih spremnika pokazuje koliki utjecaj na baterije imaju snage punjenja i pražnjenja te koliki utjecaj efikasnosti imaju na ostvarenje profita, kojeg je u cilju maksimizirati te se zbog toga proučavaju i dvije vrste tržišta s 15-minutnim i 60-minutnim vremenskim intervalima trgovanja i prikazuju rezultati te odlučuje o isplativosti takvih sustava i novih oblika tržišta.

Abstract (english)

The optimal bidding of lithium-ion battery technology in energy markets is commonly modeled in the literature using a generic energy storage model. However, lithium-ion batteries have specific characteristics compared to other energy storage systems. Therefore, this thesis explores precise battery models found in the literature, including some that are commonly used and others that are experimental, and implements them into an optimal offering model. The model is then verified using a laboratory setup. Calculating the efficiency of such storage systems demonstrates the impact that charging and discharging power have on batteries, as well as the influence of efficiency on profit maximization. To achieve this goal, two types of markets with 15-minute and 60-minute trading intervals are studied, and the results are presented. Based on these results, decisions can be made regarding the profitability of such systems and new market formats.
