Evaluation of possibilities for voltage control in a LV distribution network
Bolgár, Robert ; Drápela, Jiří (referee) ; Topolánek, David (advisor)
This paper deals with possible ways of voltage regulation. Theoretical part includes a search of published methods and the available voltage regulators. Acquired theoretical knowledge has been applied in the development of mathematical models of two selected controllers applied to the testing network. The result of this work is a summary of the outcomes of dynamic simulations with two selected regulators at various locations in testing network. Comparing the results of dynamic simulation for two selected states was chosen the most appropriate regulator and its optimal location in testing network.

Model of electric energy storage with management system based on general assumptions
Sedlák, Miroslav ; Kopička, Marek (referee) ; Radil, Lukáš (advisor)
The accumulation of electricity as an issue is becoming more important and it’s importance is constantly growing. This is due to the fact that more renewable energy sources, mainly photovoltaic and wind power plants, are being incorporated into the electricity system, causing changes in the power grid performance. Changing in the behavior of consumers of electricity can cause further changes in the network. The ability for compensations of these changes in the power grid has just accumulation systems. This Thesis for Master’s Degree presents selected storage systems and ways in which energy can be stored. Further, in this work, a model of accumulation system with management based on general conditions will be created. This model will be tested and its behavior detected under the limit conditions.

Charging Stations for Electric Vehicles
Zajac, Tomáš ; Ptáček, Michal (referee) ; Radil, Lukáš (advisor)
Bachelor´s thesis deals with issues of electric vehicle and EV charging. In its first part, categorization of EV´s is listed alongside with description of energy accumulation used in EVs and it´s key features. Furthermore, key mechanisms regarding EV charging standards and equipment are defined and the possibilities of varying charging station designs are presented and described. First part is closed by short overview of trends and innovations. Next part is focused on operating costs analysis of electric vehicles and vehicles with internal combustion engine. Final part deals with selection of charging station, creation and description of mathematical model of its charging cycle. Impact on grid is discussed along with optional partial decoupling of the load from the grid, achieved by the application of energy storage elements – buffer accumulation. Thesis is closed by proposal for calculation methodology for capital and operating costs analysis. This analysis is programmed and the overall cost of the investment is discussed.
