Modern protection of distributed energy resources
Bučko, Ondrej ; Kopička, Marek (referee) ; Topolánek, David (advisor)
The aim of this thesis is to describe distributed energy resources (DER) protection system’s main problems and to suggests their possible solutions. The second part is focused on collecting information and description of the new functional principles of protection devices used for protecting distribution network against backwards influences from the DER. The purpose of the thesis is the description of functional principles of the protection devices that are not commonly used in the distribution networks of the Czech Republic. In addition, the schemes of functional blocks of the protection devices that help to configure or project them are also part of this thesis.

Islanding Detection
Bárta, Jan ; Ptáček, Michal (referee) ; Kopička, Marek (advisor)
The bachelor thesis discusses islanding in electric power system and various methods for its detection. The thesis contains a list and description of legislation concerned with islanding, description of few selected islanding detection methods, and their comparison. The practical part of the thesis consists of simulations of several detection methods performed in the virtual environment of PSCAD and their evaluation.
