Distribution system support by power management of battery systems in charging mode and charging systems for electric vehicles
Rodionov, Vladislav ; Mastný, Petr (referee) ; Drápela, Jiří (advisor)
The thesis focuses on the power management support of battery systems in charging mode and charging systems for electric vehicles in the LV network. The thesis includes an overview of the distribution network of the Czech Republic, means of voltage regulation and the existing legislative framework for the connection of charging systems. The thesis describes the methods of active and reactive power control depending on the voltage and frequency. The practical part focuses on the simulation of grid support at different penetration levels of BESS and EVC in MATLAB Simulink and the verification of the support function on a laboratory system. In the last part, the methods of implementing the control system for BESS and EVC operating in the LV grid are specified.

Voltage quality index for distribution systems voltage quality benchmarking
Hausner, Josef ; Topolánek, David (referee) ; Drápela, Jiří (advisor)
This Master’s thesis deals with design of a new method for voltage quality benchmarking using voltage quality index. This index should determinate total voltage quality in the power grid and compare voltage quality in different places. There is design of several algorithms which value measured parameters in this thesis. The best suitable algorithm is selected. Program for this algorithm was compiled in GUI Matlab. The algorithm is verified by using measured parameters in this program. The last part of this thesis is focused on possible usage of created algorithm.
