Black coal position in the Czech energy sector
Kolarčík, Vojtěch ; Škvařil, Jan (referee) ; Pospíšil, Jiří (advisor)
This bachelor‘s thesis describes role of coal (especially the black) on the energy industry of Czech Republic. It attends to present sort of reserves in the Word and by us. Next it evaluates actual sort of energy industry. Closely analyses the power station Dětmarovice. It looks for possibilities enjoyment of coal in the future not only in the energy sector.

Thermodynamic cycles used in power engineering
Suchomel, Josef ; Kracík, Petr (referee) ; Baláš, Marek (advisor)
Power engineering is one of the most important parts of industry. Among other things, it deals with production of electricity, without which many of us can no longer even imagine life. All energy devices can be described on the basis of different thermodynamic cycles. And with these thermodynamic cycles this thesis deals. It lists both, the most important cycles, such as Rankin Clausius cycle, which is the basic cycle of most of the power plants, as well as less known, resp. almost new thermodynamic cycles. The emphasis of the whole work is also focused on the advantages and limitations of the stated cycles and on their application in practise, too.

The swirl turbine design for small water power Hovězí.
Oliva, Štěpán ; Neumayer, Oldřich (referee) ; Haluza, Miloslav (advisor)
The aim of this work was to develop a proposal regarding hydro-energy potential of small flows of water through the city „Hovězí near Vsetín“. The available water energy was used for running a Swirl Turbine featuring a siphon arrangement. This new concept makes use of a modified Kaplan Turbine, operating at small water heads. It operates also at higher revolutions and has higher discharge.

The Analysis of Factors Affecting Electricity Consumption
Seiml, Jan ; Mařica, Lukáš (referee) ; Toman, Petr (advisor)
The aim of this thesis is to describe the course of consumption of electricity. One of the feasible ways of description is statistical analysis, which enables to calculate statistically significant factors and their combinations that contributed to the course of consumption of electricity. These factors may be used for modulation of future electricity consumption, and therefore also for long-time prediction. The second chapter discusses the expansion of electricity usage in the Czech Republic from the turn of the 19th century until nowadays. The chapter describes the development of transmission system, development of electricity consumption in the sectors of the national economy, possibilities of using electric energy, and overall balance of electricity and sources of energy. The third chapter presents an overview of usage and consumption of electrical energy in the neighboring European countries as well as in the most interesting countries of the World. The fourth chapter contains statistical analysis. The first part of the chapter details a list of the analyzed quantities of individual consumptions, of the investigated factors, and the analyzed countries. Further, the chapter explains the method of statistical analysis via using simple and multiple regression and its subsequent application and evaluation for the Czech Republic and the others European countries. According to the result, it is GDP that has the main impact on the trends in the course of consumption of electricity. However, it is necessary to consider other factors influencing the consumption of electricity, too, and not rely solely on GDP in terms of long-time prediction of electricity consumption. The fifth chapter discusses the reduction of electricity consumption and savings, which can be both political and macroeconomic result. Quantification of savings is not always unequivocal and any cost-saving actions can lead to an increase in electricity consumption, which can, in effect, be bigger than any possible savings.

Risk Engineering in Czech Power Engineering
Míčková, Petra ; Krebs, Zbyněk (referee) ; Toman, Petr (advisor)
The work focuses on risk management in the Czech power engineering, introduces its functioning and connections. It also explains some of the general principles of risk management, its importance in the energy sector and energy projects. Selected risk management methods are described, which is the basis for the recommendation of one of them for application in the field of power engineering. The selected method is further demonstrated in the example of power energy project and its enhancements are proposed.

Advanced Stochastic Programming Models in Power Engineering
Pavelka, Ondřej ; Štětina, Josef (referee) ; Popela, Pavel (advisor)
This diploma thesis applies stochastic optimization in the field of the power engineering. In the thesis first part, the needed mathematical theory is described, specifically mathematical, linear, nonlinear, integer and stochastic programming. The second part deals with the heating plant, in which heat is generated by gas and biomass boilers. The aim of this thesis is to design a model for the schedule planning of these boilers. The model is based on two stage stochastic programming with scenario approach. Then the model is solved by GAMS software. In the final part of the text, the focus is on the model sensitivity analysis and suggestions for future improvement.

The Proposal of the Business development of the Company Operating on the Electricity Market
Matiovský, David ; MBA, Kamil Komenda, (referee) ; Bumberová, Veronika (advisor)
The dissertation target was to define the strategical concept of the company QUANTUM development. The company QUANTUM is the trader with the commodity of electricity operating the Czech Republic market. The theoretical part of the dissertation targets at the item of the company development and the process of the strategical management. There is the analytical methodology defined as well. The analytical part of the dissertation defines the practical implementation of the analytical concepts of the business environment of the company with the aim to define the impact factors influencing the company. The strategical concept of the business development of the company was defined and implemented due to the conclusion of the analysis with the aim to maintain the competitive position of the company in the Czech energy market. The definition of the strategy implementation reacts at the analysis of the defined threats and opportunities and the evaluation of the risks.

The Proposal of the Business development of the Company Operating on the Electricity Market
Matiovský, David ; MBA, Kamil Komenda, (referee) ; Bumberová, Veronika (advisor)
This diploma thesis deals with the creation of the development plan within the selected portfolio of services on the electricity market. The theoretical part focuses on a detailed description of the possibilities of company development and strategic management issues, especially on selected analyzes of general, market and internal environment. In the analytical part are identified and analyzed the key factors affecting the company affecting its operation in the electricity market, as well as the evaluation of the internal environment of the company. Based on the results of the analyzes, a proposal for the development of QUANTUM, a.s. to consolidate the electricity market position and steps to achieve the chosen strategy. The proposals also include a risk assesment and evaluation of the benefits of the proposed strategy.
