Alternative Energy Sources and Their Integration into the Concept of Smart Grids
Kopička, Marek ; Procházka, Jiří (referee) ; Baxant, Petr (advisor)
This work deals mainly with electrical energy. In the first part is focused on alternative energy sources, and describes structure of consumption and production of electricity over the past few years, during which is focuses on renewable energy sources. In this context, assesses the conditions for alternative energy sources in the Czech Republic from the perspective of the legislative, as well as current status and potential of alternative energy sources and tries to predict the development of these issues. The next section describes the Smart Grids as a means to achieve these goals. There are presented the basic features of this system, its goals and challenges, a description of the integration of Smart Grids with other sources of electricity and the benefits of using Smart Grids both from the perspective of user and from the perspective of system. Other parts are focused on distributed control systems in the energy sector, its development and principle. The last part is devoted to consideration of the role of alternative energy sources and distributed generation in Smart Grids.

Installation of small wind power station
Puchnar, Jiří ; Vaněk, Jiří (referee) ; Křivík, Petr (advisor)
This work is focused on the power engineering of the Czech Republic, particularly the alternative and its subset, wind power. Introduction acquaints readers with the state of energy in the country. They're the facts of the historical development of energy in Czechoslovakia and its status today. Representation of particular sources which are involved in the so-called. "Big Energy", their description and production. Each of the resources used is briefly described and discussed basic advantages and disadvantages arising from the nature of the source. It is also outlined the possible development of energy and change in the application of these resources in the future. The conclusion is devoted to alternative energy sources. Strives to cover the positive and negative aspects. It also shows the effect of alternative energy sources to power grid stability. The conclusion of this chapter is devoted to draft measures to increase the use of alternative energy sources in the energy mix of the Czech Republic. The second part is devoted to experimental measurements on small wind turbine JPT-100 from Jetpro Technology, Inc. The beginning describes the basic mathematical methods for calculating wind power and wind turbine itself. The text is accompanied by illustrative graphs. Another part deals with the actual wind turbine JPT-100. There are mentioned its characteristics, complete description of measuring workplace and measurement results.

Utilization of Knowledge Systems and Bases for Selection and Evaluation of Domestic Electrical Installations.
Haluza, Miroslav ; Martínek, Zbyněk (referee) ; Gurecký, Jiří (referee) ; Toman, Petr (advisor)
My doctoral thesis deals with use of the sophisticated methods for the selection of technical and economic solution of electrical wiring. This solution is based not only on a price but also on many other criteria such as a comfort, service, durability etc. The focus of the work is a treatise on wiring systems from a global perspective, where it is impossible to use a conventional approach for objective evaluation and selection of the appropriate electrical wiring system (because of the complexity of such systems and their interdependencies). In the four chapter are given information of an energy consumption (the total consumption and household consumption). In this chapter is given also a consumption prediction – especially for households. Following is an overview of possible measures for reducing electricity consumption in households. In the next part of this thesis are solved the knowledge, respectively expert systems for use in an electrical engineering – especially for a suitable tool for the selection and evaluation of households wiring electrical system. The result of this work provides a possible solution for a selection of wiring electrical system for households (focusing on the intelligent wiring) – from a technical and economic point of view and with using an innovative approach. The main contribution of this work is a proposal of the main part of the knowledge base. This base could be as a basis for knowledge, respectively for an evaluating technical and economical solution of an electrical wiring system – the expert system includes also a feedback function of an effectiveness solution, use value, price etc., which would also serve as a knowledge base.

Alternative energy sources
Stránský, Jaroslav ; Moskalík, Jiří (referee) ; Škvařil, Jan (advisor)
In this work, I tried to summarize the current state of world energy resources that we use to convert into electrical energy. There is solved the question of compensation running short supplies of fossil fuels and reduce discharge of greenhouse gasses. I´m looking for suitable compensation in department of alternative energy sources, among which I included the power of the Sun, water, wind, geothermal energy, using heat pumps, combustion energy, nuclear energy, fuel cells and hydrogen use. About anyone of replacing sources you learn about its history, advantages and disadvantages, the principle of function energy transform devices, and compare the potential that is available in the CR and in the world.

Innovation and Extension of Solar Concentrator system
Vasyliev, Mykola ; Radil, Lukáš (referee) ; Baxant, Petr (advisor)
The bachelor thesis is focused on the innovation and expansion of the solar concentrator system, which was originally created by Robert Hrachiar in 2016 [1]. The description and implementation of the concentrator system is given in the bachelor's thesis entitled Solar applications with concentrator elements. The bachelor thesis contains a description of basic knowledge for the operation of a solar concentrator system, analysis of the original project, identification of deficiencies and the relevant improvement of the concentrator system. The advantages of solar energy over other alternative energy sources and the principle of operation of solar systems with separate mirrors are described in the theoretical part. The analysis of the project and the identification of deficiencies in the section described the identified deficiencies that arose during 2 years of operation of the solar system. Investigation of the causes of deficiencies and negative consequences. The Modernization section contains a description of the relevant improvement of the concentrator system based on the identified shortcomings, innovation and expansion based on the experience of using a similar system in the country and in the world.

Alternative energy sources in the selected region
NOVOTNÁ, Věra
This bachelor thesis is focused on the use of alternative sources in a selected region. More specifically, it deals with biogas plants in a selected region. The thesis is divided into theoretical part and practical part. The theoretical part contains general information, such as types of biogas plants, their general usage, their strategies, from which they draw material for energy production and where they invest this energy. The practical part consists of an analysis of the activities of biogas plants in the selected region. This analysis works with specific data on activities, strategies of specific biogas plants, their drawing subsidies or their plans for the future. The analysis includes interviews with representatives of selected biogas plants, from which the results of the survey outcome.
