Business Project in the Area of Renewable Resources of Energy
Kerndl, Michal ; Kallabová,, Eva (referee) ; Heralecký, Tomáš (advisor)
The aim of my thesis, which is called „Business project in the area of renewable energy resources“, is to analyze business opportunities in the area of renewable energy resources, which have been highly actual and discussed recently, whether in term of benefit for environment or in connection with international problem of shortness in energy resources. Result of this thesis is, on the basis of the analysis, to define recommendations in the form of optimal proposal for realization. The thesis is engaged in description of current state in the area of the renewable energy resources, their utilization in practice and consequential proposals for realization including project financial plan. The thesis is also engaged in possibilities of state budget and EU grants use.

Different use of the wind energy.
Lakva, Petr ; Boráň, Jaroslav (referee) ; Jícha, Jaroslav (advisor)
The target of this bachelor study is describing basic type of renewable sources of energy. Emphasis is put on wind energy. Another part is description of different types of wind generators. In the last part study deals with problem of accumulation of wind energy for later use, thanks to compression of air in the underground mines.

Foundation of the Ecological Energy Firm
Dostál, Jaroslav ; Němcová, Hana (referee) ; Bayerová, Vladimíra (advisor)
The master’s thesis follows up the possibility of using renewable for making electric power. It detects conditions of further development in this discipline and external factors which are applied to business. It rates from economic view little hydroelectric, wind and photovoltaic power stations. In business plan it elaborates in detail prosecution of the little hydroelectric plants, which is at the end subjected to financial analysis and it’s decided if this business makes sense.

Design of a micro waterpower turbines for low head and low dicharge
Macek, Libor ; Fic, Miloslav (referee) ; Štigler, Jaroslav (advisor)
This diploma thesis discusses the issue of finding type of water turbine for very low heads and low discharges, which could be operated as mobile micro hydropower plant in island mode. Thesis deals with summary of appropriate choices of water turbine for needs of micro hydropower plant. Essential part of diploma thesis deals with design of optimized waterwheel. Waterwheel was chosen because commercial high-speed turbines have low efficiency for low heads. Waterwheel was manufactured and measured in laboratories of Fluid engineering. Measurement output was discharge and efficiency characteristic of turbine. The price calculation was made after manufacture.

The tooth pump in the turbine regime
Tyburec, Adam ; Dobšáková, Lenka (referee) ; Haluza, Miloslav (advisor)
The objective of this diploma study is to develop and secure production of gear turbine with very low specific speed in comparison with conventional turbines. The first part of the work deals with already performed research of similar hydrostatic turbines. It is followed by construction design, including complete drawing documentation. The production of the prototype is secured by an external company. Finally, an experimental measurement of the characteristics of the designed turbine is performed in the laboratories of Fluid Engineering.

Real potential of renewable energy sources in Czech republic
Tofel, Jan ; Kropáč, Jiří (referee) ; Máša, Vítězslav (advisor)
The aim of this thesis is to present the basic characteristics of renewable energy sources and assess their potential for further use in the Czech Republic. Based on studying literature, statistics, foreign experience and consultation with experts is reviewed which of these resources in the Czech Republic give meaning or how to ensure their effective use. The individual chapters of the thesis describe in detail the characteristics of renewable energy and in the final chapter are reviewed economic and environmental terms.

Accumulation of Energy from Renewable Energy Sources
Heller, Ondřej ; Radil, Lukáš (referee) ; Mastný, Petr (advisor)
The objective of the first part of master’s thesis is mapping the potential of various types of renewable sources in Europe and Czech Republic, especially solar energy, wind energy, water energy and biomass. There are described principals and ways of energy generation from these sources, brief overview of current technologies, and also their advantages and limitations. An important part is electric supply continuity from renewable sources, there are large differences and the resulting to restrictions on construction and connecting the units to the power system. In this work there are mentioned some impacts on network and rates of change of supply, some sources are also evaluated in terms of maximum power, that can be connected to the power system in our country. The conclusion of the first part is dedicated to energy storage technologies, which are suitable and usable for renewable sources, there are described their principals, properties, status of development and types of aplications, in which these technologies are used. This chapter also focusses on the price level of each technology. The second part of the thesis deals with 1 MWp on-grid photovoltaic power plant design. This design includes also the redox flow batteries accumulation, the first variant calculates on 24-hour steady energy supply, the second optimalized variant calculates on daily energy supply. There are the accumulation system costs estimated and also the payback period for the both variants. Additionally there is also determined minimum penalization for cost-effective operation. The last part is dedicated to changes of impact on the local grid and changes of system impacts, after the accumulation system is installed.
