The use of energy storage with converter in different operating modes of the system for energy management

V diplomskem delu so predstavljeni: osnovno delovanje in zgradba litij-ionskih baterijskih celic ter sestavljeni baterijski paketi tehnologije LFP, NMC, NCA in LTO, primerni za shranjevanje večjih količin energije. Baterijski paketi so uporabljeni v kombinaciji s sistemom za upravljanje z energijo za glajenje odjema električne energije gospodinjstva iz omrežja, vključno z omogočenim polnjenjem baterije električnega vozila. Prikazan je tudi primer uporabe hranilnika energije za glajenje proizvodnje in porabe električne energije v kombinaciji s sončno elektrarno v gospodinjstvu.The diploma thesis deals with basics in operation and structure of lithium-ion battery cells and packages in LFP, NMC, NCA, and LTO technologies that are suitable for storing large amount of energy. The discussed battery packages are used as a part of a home energy management system (HEMS) where the energy consumption of the house with PV system, energy supply from the grid, and charging of an electric vehicle are considered. The simulations performed in the thesis demonstrate how the battery system can be used inside aforementioned HEMS in order to minimize the maximal power delivered from the grid and the power for fluctuation during the given interval of the observation
