20.500.12556/RUL-149444 Model litij-ionske celice in baterijskega hranilnika energije Model of Lithium-Ion cell and battery energy storage Diplomsko delo govori o izdelavi simulacijskega modela litij-ionske baterije in modeliranju baterijskega hranilnika energije. V uvodnih poglavjih je opravljen pregled raznih baterijskih tehnologij in njihova primerjava, na podlagi katere so za hranilnik izbrane litij-ionske baterije. Nato je analiziran princip delovanja teh baterij, skupaj z njihovo izdelavo in obratovalnimi lastnostmi. Predstavljene so tudi možne nevarnosti. Posledično je izpeljan podroben matematični model ekvivalentnega nadomestnega vezja za litij-ionsko baterijsko celico. Opravljen je tudi študij baterijskih hranilnikov energije, ki vključuje funkcionalnosti sestavnih delov in njihovo izdelavo. Pregledana je tudi integracija hranilnikov v obstoječa omrežja in delovanje v kombinaciji z obnovljivimi viri energije, kar predstavlja enega ključnih načinov rabe hranilnikov v razvoju elektroenergetskih omrežij za zmanjševanje podnebnih vplivov. Opisan je proces izdelave simulacijskega modela litij-ionske celice, skupaj s testiranjem in validacijo tega modela v programskem okolju MATLAB/Simulink. Ta je nato uporabljen v simulaciji baterijskega hranilnika energije. V to je vključena izdelava nadzornega sistema, ki skrbi za varno obratovanje hranilnika in ga ščiti pred poškodbami. Za zagotavljanje zanesljivosti modela je ključnega pomena testiranje, kjer so preverjene številne značilnosti modela v z različnih obratovalnih stanjih. Poleg tega je podrobno testirana tudi funkcionalnost nadzornega sistema hranilnika z vsemi varnostnimi omejitvami. Tako model celice kot model nadzornega sistema se izkažeta za zanesljiva in nudita realistične simulacije obratovanja tovrstnega hranilnika. The thesis discusses the development of a simulation model for a lithium-ion battery and the modelling of an energy storage system. In the introductory chapters, various battery technologies are reviewed and compared, based on which lithium-ion batteries are selected to be used in the storage system. The operating principle of these batteries is then analysed, along with their construction and operational characteristics. Possible dangers are also highlighted. As a result, a detailed mathematical equivalent circuit model for a lithium-ion battery cell is derived. A study on battery energy storage systems is conducted, which encompasses the functionalities its various components and their construction. The integration of these storage systems into existing networks and their operation in combination with renewable energy sources is also reviewed. This represents one of the primary ways to use battery energy storage systems in the development of electrical networks to reduce climate impacts. The process of creating a simulation model for a lithium-ion cell is described, accompanied by testing and validation of this model in the MATLAB/Simulink environment. This model is then used in the simulation of an energy storage system. The development of battery management system is included, ensuring the safe operation of the storage system and protecting it from damages and faults. Testing is needed to ensure the reliability of the model. Numerous characteristics of the model are examined under various operational conditions. Additionally, the functionality of the battery management system is thoroughly tested. Both the cell model and the management system model prove to be reliable, offering realistic simulations of the battery energy storage system's operation.
