Design Kalina cycle for geothermal power plant and its turbine.
Luermann, Július ; Martinec, Jiří (referee) ; Škorpík, Jiří (advisor)
This master’s thesis analyses Kalina cycle, a power cycle where ammonia – water solution is used as a working fluid. The first part of this study introduces us to the Kalina cycle, presents its advantages and disadvantages, characteristics of the working fluid and its applications. Second section concerns with the method of cycle design and describes the calculation model made in this thesis. The calculation model is attached in a separate .XLSM file. The third part shows calculation of the cycle for given parameters, determination of cycle efficiency and main proportions of the thermal turbine. In the conclusion are the interpretations of the calculations results.

Utilization of renewable energy sources in Czech Republic
Kopička, Marek ; Bok, Jaromír (referee) ; Matoušek, Antonín (advisor)
This thesis deals with consideration of energy facilities structure in Czech Republic. It is depicted in it their evolution from point of: electric energy consumption, structures of energy facilities and electricity prices. Further, is here depicted a production of electric energy for the year 2009, from the point of: produce, sources, consumption and ratio of factories. Of course, the RSE (renewable sources of energy) effect and share of scope on this evolution and structure, is also mentioned here. The next part is pointed to basic description of each sources of electric energy. It is not mentioned here only factories which uses for it´s production renewable primary sources but also another types of factories. Their pros and cons are also summarized. The last part of this work is a thought of realization of fictive project, which could replace a part of steam power plants' share by producing electric energy through renewable sources. It is re-counted and suggested here a few possibilities of this realization from the point of needed installed power and approximate estimation of capital expenditure.

Renewable energy sources for one-family house
Burýšek, Jan ; Špiláček, Michal (referee) ; Fortelný, Zdeněk (advisor)
This Bachelor´s Thesis deals with the topic of Renewable Energy Resources. It is divided into two main parts. The first part is a research on renewable resources of energy which are available in the Czech Republic. The second part is focused on use of particular resources in a chosen object (house) and their subsequent efficiency evaluation.

Utilization renewable energy sources inside of EPS Czech Republik
Zmeškal, Pavel ; Procházka, Zdeněk (referee) ; Matoušek, Antonín (advisor)
The purpose of this work was the analysis of current state and further development of renewable energy in the Czech Republic. And next their effects on the electricity system of the Czech Republic. On the basis of established facts has been developed actual state of renewable energy sources. The current situation is only orientation and is still changing at this time. Another objective was to evaluate the various renewable energy sources in terms of their impact on the electricity system and recoverability in the Czech Republic. In more detail were read up the conditions for the wind power plants operation and their connection to the electricity system of Czech Republic. In fine were discuss the impact of renewable energy sources on electricity system and prerequisite for their further development in the Czech Republic.

Sustainable energy sources
Doležal, Jan ; Nerud, Pavel (referee) ; Škvařil, Jan (advisor)
This bachelor’s thesis is a recherche dealing with sustainable energy sources. It lists and describes the various sources and shows their operating principles. In the last part it evaluates their current use in the Czech Republic and the possibilities for further development from economic and technical point of view.

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.

Assessment of the impact of different types of RES in the power system
Zmeškal, Pavel ; Matoušek, Antonín (referee) ; Mastný, Petr (advisor)
This thesis deals with usage of each kind of RES under conditions of Czech republic and their usage at areas placed in. Consequently supplied RES output power at time and its influence on reliability of supply in EPS CZ. Way of operation of RES from point of view of requirement on regulation and control of operation of EPS is more studied on operation of different kinds of wind power plants, which due to its variable output power affects not only EPS CZ. At final caption, economic influence of RES to EPS is reviewed as a unit, increasingly claims on regulation, increasingly benefit on support of RES. All these influences increase price of electricity for end user.

Using renewable energy sources
Vaňko, Adam ; Bátora, Branislav (referee) ; Matoušek, Antonín (advisor)
Thesis deals with the issue of renewable energy sources. It contains the description of their usage at present as well as the possibilities of their installation. When dealing with the individual types of sources the thesis states their advantages, disadvantages and the facts concerning their further development. Technical development brings us new and perspective types of renewable energy sources, the description of some of them can be found in the thesis as well. The second part of the thesis is focused on the solution of electric power supply for a holiday cottage. Authonomy photovoltaic system is suitable for its application. The system is designed to have an ability to supply electrical units in the cottage during the whole year. To be able to consider profitability of the photovoltaic system installation the thesis contains the project of low voltage energy branch connection. This branch line of 1200 m in length is properly designed and the thesis states its capital costs as well. Financial comparison of the photovoltaic system costs on the one hand and the costs of low voltage branch line on the other hand in the next 30 years of usage proves the profitability of the photovoltaic system.

Barriers of renewable sources expansion in the Czech Republic
Lukášek, Kamil ; Březina, Ladislav (referee) ; Mastný, Petr (advisor)
Currently, there is no publication that concerns the renewable resources comprehensively in the Czech Republic. This publication defines the renewable resources in general meaning. Whereas the physical and legal definitions of the renewable resources are different, text explains the principle of production of electricity according to the legal definition. When the renewable resources are being constructed, it's important to achieve the optimal operating conditions. To achieve these conditions, it's necessary to locate the renewable resource in the Czech Republic. The operations of renewable resources are partly financed by the country, in order to be more interesting for the investors. Further on, the conditions of connection to electrical distribution system are defined. The impact of renewable resources on electrical distribution system. Finally the conception of renewable electrical energy resource for region of East Bohemia is designed.

Alternative energy sources for family house
Stacha, Radek ; Fortelný, Zdeněk (referee) ; Škvařil, Jan (advisor)
Bachelor thesis is focused on alternative sources of energy for the house and their evaluation. The first part focuses on the general view on alternative energy sources and making explicit the house of each resource of which the assessment is undertaken. The next chapters are focused on each types of renewables for which will be the conclusion in the end of each section for the assessment of a given house. The conclusion is evaulated for the selected type of alternative energy resources towards normally used ones.
