20.500.12556/DKUM-79812 Potencial uporabe hranilnikov energije z namenom doseganja samooskrbe z električno energijo iz sončnih elektrarn The potential of using energy storage systems in order to achieve energy self- sufficiency from photovoltaic systems Magistrsko delo obravnava uporabo hranilnikov energije za skladiščenje proizvedene energije iz sončnih elektrarn. V tem delu je analizirano obratovanje baterijskega hranilnika energije v kombinaciji s sončno elektrarno na podlagi realnih izmerjenih podatkov v obdobju dveh let. Analiziran je vpliv integracije baterijskega hranilnika energije na zagotavljanje samooskrbe z električno energijo. Narejena je tudi študija treh različnih primerov dimenzioniranja sistema. V prvem primeru je dimenzioniran sistem, ki zagotavlja popolno samooskrbo z električno energijo, v drugem primeru je dimenzioniran sistem, ki omogoča neodvisno obratovanje od omrežja, v tretjem primeru pa je dimenzioniran sistem, ki shranjuje višek proizvedene električne energije iz sončne elektrarne v obliki vodika. Opravljena je tudi ekonomska analiza obstoječega sistema sončne elektrarne in baterijskega hranilnika energije. Prav tako je narejena ekonomska analiza vseh treh študij dimenzioniranja sistema. Rezultat magistrskega dela dokazuje, da je možno dimenzionirati sisteme za popolno samooskrbo in neodvisno obratovanje od omrežja, vendar so ti sistemi predimenzionirani in so ekonomsko neupravičeni. Splošno gledano integracija hranilnikov energije negativno vpliva na ekonomsko upravičenost investicije, saj ne prinaša neposrednih finančnih koristi. Kazalci ekonomske upravičenosti investicije so pokazali, da se investicija v sisteme sončne elektrarne in hranilnike energije ne splača. Iz ekonomskega vidika so hranilniki vodika boljši za shranjevanje energije od baterijskih hranilnikov energije. The following thesis deals with the use of energy storage systems for the storage of produced electrical energy from photovoltaic systems. A battery energy storage systems in combination with a photovoltaic systems are analysed on the basis of real measured data over a period of two years. The impact of battery energy storage integration on the provision of self-sufficiency in electrical energy is analysed. A study of three different examples of system dimensioning has also been made. In the first case it is a dimensioned system that provides complete self-sufficiency in electrical energy, in the second case it is a dimensioned system that allows independent operation from the grid and in the third case it is a dimensioned system that stores excess electrical energy produced from photovoltaic system in the form of hydrogen. An economic analysis of the existing photovoltaic system with battery energy storage is performed. The economic analysis of all three examples of dimensioning systems has also been made. The results of the master's thesis prove that it is possible to dimension systems for complete self-sufficiency and independent operation from the grid, but these systems are oversized and are economically unjustified. In general, the integration of energy storage systems has a negative impact on the economic viability of the investment, as it does not bring direct financial benefits. Indicators of the economic viability of the investment have shown that the investment in photovoltaic systems and energy storage systems does not pay off. From the economic point of view, hydrogen storage is a better solution for storing energy than battery energy storage systems. samooskrba sončne elektrarne hranilniki energije baterije self-sufficiency photovoltaic power plants energy storage systems battery storage systems true true false [J.
