Ecological problems energetics CR
Šilar, Martin ; Bok, Jaromír (referee) ; Matoušek, Antonín (advisor)
This project presents the current status of power resources and supply in the Czech Republic and examines its different connections with ecology. The existing situation in energetics is described in the first chapter of the thesis. This chapter contains general information as well as an analysis of the progress to date related to the structure of installed power and to the amount of electricity generation and their consumption. The description of the common influence of energetics on the environment is provided in the following chapter, which also introduces the next step, namely a short survey of the characteristics of the currently used energy resources and their direct relationship to the monitored ecological problems. The practical part of the project is based on the calculation of emission in the fifteen biggest thermal power station in the Czech Republic. The calculated amounts of emission are compared with the related features of nuclear waste. The last chapter contains information about the EU legislation concerning the reduction of carbon dioxide. In this respect, there are presented also the measures planned to facilitate the reduction of carbon dioxide in Czech Republic.

Using WXT520 meter station for measuring the wind energy
Skalička, Jiří ; Macháček, Jan (referee) ; Šlezingr, Jan (advisor)
This bachelor’s thesis introduces the basics of wind energy. It explains the formation of wind, various types of wind engines, different types of wind power plants (divided by installed capacity), basic methods for wind array determination and wind potential in Czech Republic. Then it turns to Vaisala Weather Transmitter WXT520, which is ideal for measurements in wind energy industries. It explains the transmitter’s basic functions, connection and communication options. Practical part of this thesis is dedicated to realization of measurement using National Instruments CompactRIO platform and LabView development environment. Output of this thesis is a program for long term measurements of meteorological data, analysis and archiving of this data.

Renewable Energy Auction Schemes
Jörka, Lukáš ; Macháček, Jan (referee) ; Radil, Lukáš (advisor)
The bachelor thesis deals with the current trend in the field of support for renewable energy sources – the transition from fixed payments to auction mechanisms. Firstly, the thesis describes principles of auctions in the field of RES support and capacity mechanisms. Subsequently, there are described advantages and disadvantages of auctions for RES support and defined their basic elements. This thesis deals with the current state of the global RES market and the description of the current state of the auctions implementation in Europe with focus on the auctions held in Germany and the United Kingdom. Furthermore, the thesis deals with the current state of the RES market in the Czech Republic describing the development of RES support in the past, the current situation and expected future development. The last chapter is devoted to the fictional economic model of wind park, for which the economic evaluation by the NPV method is performed for different values of the input parameters.

Offshore and inland type of wind power
Chromec, Tomáš ; Kracík, Petr (referee) ; Škorpík, Jiří (advisor)
This bachelor‘s thesis focuses on wind energy sector. The first part describes the modern history of this industry. The brief description of the main differences between onshore and offshore wind farms followed an extensive chapter, which describes the diversification of wind power solutions and diversification in the case of wind farms located on the sea. Fluctuating needs for backup power sources in this work is included in chapter, which briefly describes the most appropriate energy storage devices. This is followed by section dealing with the economics of wind turbines. Possible negative impacts of wind energy are discussed in the final chapter about environmental impacts associated with wind power applications.

The Project Proposal for Construction of Wind Turbines
Horák, Filip ; Ondráček, Pavel (referee) ; Doskočil, Radek (advisor)
This bachelor's thesis deals with a project proposal for construction of wind turbines. The first part is consisted of definitions of some basic terms of project management and also of description of methods, techniques and tools of project management, which represents theoretical backround for two following parts of the thesis. There is analyzed wind energy in Czech Republic and the company and its environment and gradually produced a plan of project as requested by a certain company. for supporting their decision-making process. The results of this thesis help other investors or public to understand the process of wind turbines construction.

Seasonal variation in renewable energy supply
Rymešová, Lucie ; Škorpík, Jiří (referee) ; Linda, Jakub (advisor)
This bachelor’s thesis focuses on seasonal fluctuations in energy supply from renewable sources, specifically photovoltaic and wind power plants. It includes a literature review on renewable energy sources and their importance in the energy sector. It further explores the principles and utilization of photovoltaic and wind power plants. The thesis analyses seasonal fluctuations in energy supply by processing data from the ČHMÚ station and examines their impacts on the energy system. The results of the analysis of seasonal fluctuations are presented and compared. It is evident that solar energy has the largest share during the summer months, while wind energy has the highest contribution during the winter months. The results suggest that a suitable combination of photovoltaic and wind power plants could suppress seasonal variations in electricity supply and contribute to its stable production within smaller energy units.
