Abstract

Operater trga z elektriko v sklopu bilančnega obračuna preverja, ali je obratovanje bilančnih skupin usklajeno z njihovim tržnim planom, zaznana odstopanja pa jim zaračunava. Strošek odstopanj za bilančne skupine ni zanemarljiv. Iz tega razloga se sprašujejo, če obstajajo načini, s katerimi bi ta odstopanja lahko učinkovito zmanjševali. Magistrsko delo obravnava modeliranje baterijskega hranilnika in njegovo vključitev med elektroenergetski sistem in odjemalca. Nadalje je opisan vpliv baterijskega hranilnika na odstopanja in z njimi povezani stroški. Predstavljen je postopek analize ekonomske upravičenosti investicije v baterijski hranilnik z upoštevanjem stroška investicije, letnih denarnih prilivov in odlivov. V delu je preko metod neto sedanje vrednosti in notranje stopnje donosa ovrednotena ekonomska upravičenost investicije za različne konfiguracije baterijskega hranilnika s stališča moči in kapacitete. Dodatno je izvedena še analiza občutljivosti ob predpostavljenih vrednostih vplivnih parametrov za leto 2025. Na koncu so podani napotki za izbiro primerne konfiguracije hranilnika, ki bi ustrezala rešitvi obravnavanega izziva.

Secondary title: Reducing electricity demand imbalances with battery storage
Secondary abstract: As part of the imbalance settlement, the power market operator checks that the balance groups are operating in accordance with their market plan and charges them for any deviations found. The costs of deviations are not negligible for the balance groups. Therefore, the question arises whether there are ways to effectively reduce these deviations. The thesis deals with the modelling of battery storage and its integration between the electricity system and the customer. It further describes the impact of battery storage on the deviations and the associated costs. A procedure for analysing the economic viability of an investment in a battery storage is presented, considering the investment costs, annual cash inflows and cash outflows. The economic viability of the investment is assessed for different battery storage configurations in terms of power and capacity using the net present value and internal rate of return methods. In addition, a sensitivity analysis is carried out assuming the values of the impact parameters for the year 2025. Finally, guidance is given on how to select an appropriate storage configuration to meet the challenge at hand.
