PV inverter and hybrid inverter test bench
Sedlačko, Jozef ; Morávek, Jan (referee) ; Vrána, Michal (advisor)
Electricity production from photovoltaic power plants has been one of the fastest growing energy industries in the last decade. Number of small power inverters working parallelly with the low voltage grid is growing. At the same time, the requirements for the correct behaviour of network inverters in the network by the distribution grid operators are also increasing. The thesis deals with creation of a workplace for testing the operational and technical requirements for micro-sources. The first part of the thesis consists of literature search of inverter demands according to the current rules for parallel production operation. The second part deals with the setting up of test procedures and automation. The last part evaluates selected tests of the functions of the inverters.

Use of solar energy for electromobility
Harant, Miroslav ; Morávek, Jan (referee) ; Baxant, Petr (advisor)
The thesis deals with the use of solar energy for electromobility. First, the potential of electromobility on the current market is theoretically discussed. This issue includes mainly the producers of electrically powered vehicles, the issue of electric energy storage and the real applications of fast charging and photovoltaic charging stations. In the next part, electric cars are analyzed, which use solar energy for their function and their efficiency is compared with the effiency of combustion engines. The main part of this thesis is the design of photovoltaic charging station for electric vehicles. The final part deals with the economic evaluation of the proposed charging station.

Operating diagnostics of PVP
Prášil, Kryštof ; Morávek, Jan (referee) ; Mastný, Petr (advisor)
The bachelor thesis deals with the issue of photovoltaic power plants, especially their operational diagnostics and how to perform this diagnostics. The introduction of the work explains the principle of function of PV cells and describes the procedure for manufacturing these cells. Furthermore, there are mentioned methods of manufacturing individual components for assembling a PV panel. The next part lists the individual components of the PV power plant and describes their function in the entire system. At the same time, the connection methods of the PV plant are described. In the third part, we look at possible defects that affect the performance of PV systems and reduce their economic profitability. We will explain the defects of both the entire PV power plant and the individual panels and components. The following chapter is focused on explanation of individual variables related to PV power plants and what these variables are about. The fifth chapter deals with the content of the standard ČSN EN 62446. The last chapter concerns the diagnostics of the PV system itself, practical tests and evaluation of the results of these tests.

Controlled lighting and shading in smart house
Novák, Michael ; Morávek, Jan (referee) ; Bátora, Branislav (advisor)
This bachelor‘s thesis is focused on controlling lighting and shading in a smart house. Lighting control covers switching and dimming mechanisms. This thesis presents dimming options for different types of light sources. Following this is an overview of shading devices and system wiring, often called smart wiring. Specifically, the thesis focuses on the Foxtrot system from Teco a.s.. This work describes the sensors and actuators used for switching, dimming and shading control devices. New library of functional blocks for lighting and shading control for Foxtrot system was created, for they were not included in any standard library. All functional blocks that have use in the control of lighting or shading - including standard ones - are described in this work.
