Vpliv baterijskega hranilnika na dnevni profil odjemne moči gospodinjstva in napetostne razmere v omrežju

Kastelan, Nejc (author), Gubina, Andrej Ferdo (mentor), Pečjak, Matej (co-mentor)

Analiziraj različne parametre vključitve baterijskega hranilnika električne energije v gospodinjstvo z že prej vgrajeno fotovoltaično elektrarno. Oceni povečanje deleža samooskrbe (tj. obdobje, ko gospodinjstvo za svojo lastno rabo ne potrebuje zunanjega napajanja iz omrežja) gospodinjstva s fotovoltaično elektrarno in hranilnikom v primerjavi z gospodinjstvom brez hranilnika, po letnih časih. Dodatno preveri spremembo letni delež samooskrbe istega gospodinjstva pri zmanjšani delovni kapaciteti hranilnika. Oceni čas enostavne povračilne dobe ob predpostavki različnih cen odkupa električne energije po principu prodaje vse energije, ki ni porabljena za lastno rabo gospodinjstva. Analizaj možnost polnjenja električnega vozila z lastno proizvedeno električno energijo iz fotovoltaične elektrarne. Končno preveri močnostne in električne razmere ruralnega omrežja ob vključitvi različnega števila odjemalcev s fotovoltaično elektrarno in baterijskim hranilnikom.

• Title: The impact of the battery energy storage system on the daily profile of household power consumption and voltage conditions in the local electricity network

Abstract

Analyze the various parameters of including a battery energy storage system in a household with a previously installed photovoltaic power plant. Estimates the increase in the share of self-sufficiency (i.e. the period when the household does not need external power from the grid for its own use) of a household with a photovoltaic power plant and a storage tank compared to a household without a storage tank, by each season. In addition, it checks the change in the annual share of self-sufficiency of the same household with a reduced working capacity of the storage tank. Estimate the time of the simple payback period assuming different electricity purchase prices based on the principle of selling all energy that is not used for the household's own use. Analyze the possibility of charging an electric vehicle with self-produced electricity from a photovoltaic power plant. Finally, it checks the power and electrical conditions of the rural network with the inclusion of a different number of customers with a photovoltaic power plant and battery storage.
