Realization of Business Project - Construction of a Wind Power Station in the Czech republic
Kerndl, Michal ; Střítecký, Radim (referee) ; Heralecký, Tomáš (advisor)
The aim of the bachelor‘s thesis which is called „Realization of a business project – construction of a wind power station in the Czech republic“ is to realize a progressive business project which uses alternative sources of energy; is beneficial to the czech environment and is very actual at present, especially because of increasing prices in electrical energy and the global warming. The thesis describes present circumstances in alternative sources of energy, their practical use and proposals for realization including the financial plan of projects. The thesis is also focused on possibilites of financing from EU grants or state budget.

The Conversion Efficiency of Different Kinds of Energy into Electrical Energy and the Possibility of its Accumulation
Ostruška, Jan ; Bartošík, Tomáš (referee) ; Macháček, Jan (advisor)
The thesis deals with the issues of the conversion efficiency of different kinds of energy into electric energy. Firstly, the thesis presents a brief introduction into types of energy sources and their capacity. Then, conversion efficiency of particular direct and indirect conversion is scrutinized, pointing to factors which affect conversion efficiency. The next chapter deals with the possibilities of accumulating electric energy. These are analysed as far as conversion efficiency is concerned as well and the end of the chapter concludes with comparison of these particular possibilities. Booth parts of the process – power generation and its accumulation – are connected in comprehensive scheme of energy conversions. The thesis develops on this scheme by mathematic description of its components and by designing a simulation programme, which would show the flow of energy in the scheme.

Influence of RES to power system in Czech Republic
Vánišová, Michaela ; Bartošík, Tomáš (referee) ; Mastný, Petr (advisor)
This text deals with renewable energy sources in terms of working on the electricity network of the Czech Republic. There is the definition of renewable energy sources in the work. Next there are discussed the basic information about connecting to the distribution network. In two parts, there is mentioned and discussed the issue of operation of renewable energy resources and their effects in terms of the electricity network. The last chapter is focused on the possibility of further utilization of renewable energy sources because of their natural energy.

Study of Power Plant Connection to Power Network
Sýkora, Martin ; Kurfűrst, Jiří (referee) ; Paar, Martin (advisor)
It is necessary to judge the influences of producers on the electric compounds while creating electrical energy or during the regulation of those existing. These analyses are sorted out by so called studies of connectivity. These calculations analyze the degree of connection of the producer and the standby unit during a break-down. The results of this report are several recommendations for creating such unit and succeeding steps leading to secure the stability and safety of the electric compound operation. The aim of this thesis is to discuss about software for PC solutions for static and dynamic network model, to draft power outlet into a network of generating high voltage, to complete a study of connectivity with respect to all the distortion factor, as increased voltage, inrush current at startup, flicker, harmonic currents, interference ripple, contribution to short-circuit current, reactive power control options, and demands for compensation.

Wind Energy Use on Flat Roofs of Buildings
Tůmová, Eliška ; Kabrhel,, Michal (referee) ; Horák, Petr (referee) ; Hirš, Jiří (advisor)
The PhD thesis is focused on determination of the method by which it is possible to specify the wind energy use potential on building flat roofs. In response to the need to reduce the production of CO2 emissions and increase energy self-sufficiency, it is necessary to use alternative energy supply systems and renewable resources as much as possible. Long-term and short-term wind parameters were measured to verify the of the resulting simulation velocity flow images. Based on the defined input parameters and the completed simulation, the resulting value of the potential is determined, namely the possible production of electricity for selected small wind power plants on the roof of the selected building during one year. In the thesis the individual steps of the method are stated and the verification of the established method is determined.
