Short Circuit Currents in DC Systems
Kolařík, Robin ; Geschwinder, Lukáš (referee) ; Paar, Martin (advisor)
The bachelor thesis deals with the analysis of short-circuit currents in DC systems. The thesis introduces the possibility of application of low voltage DC distribution in commercial and industrial buildings. The second part is focused to high voltage direct current transmission. The practical part deals with the calculation of short-circuit currents of individual elements and subsequently with short-circuit conditions in the DC network. At the end of the work are evaluated advantages and disadvantages between AC and DC voltage and suitability of use in given areas.

Energy Flow Analysis In Lv Grid With High Level Penetration Of Pv Instalations
Kolarik, Robin
The article is focused on the analysis of daily energy flow in LV grid with PV installations,electric vehicles and the character of the building consumption. PV systems are situated on the roofsof the houses and use maximum roofs technical potential. Electric vehicles are divided to three categoriesand by each house are situated one electric car. Load profile of each houses are based on thestandardized load profile, whitch is allocated according to distribution tariff. The aim of this articleis to determine daily power flow analysis in municipality LV grid.
