Comparative Analysis of Renewable Energy Sources in the Selected European Countries
Konečný, David ; Borecká, Marcela (referee) ; Ellederová, Eva (advisor)
Cílem této bakalářské práce je poskytnout informace o obnovitelných zdrojích energie v Německu a v České republice, a to zejména z pohledu historického vývoje, energetické politiky, využití a možností dalšího rozvoje těchto technologií. Po shrnutí klíčových událostí a smluv s přímým vlivem na obnovitelné zdroje, práce analyzuje danou problematiku v Německu včetně energetické transformace této země, nazvané Energiewende. Stejná metodologie je použita při analýze obnovitelných zdrojů energie v České republice včetně srovnání finanční podpory obnovitelných zdrojů v obou zemích. Práce je zakončena kapitolou o vlivu, dopadech a možných důsledcích německé energetické přeměny na energetický sektor České republiky.

Draft methodology for processing and evaluation of long-term measurements on PV Panel
Žák, Tomáš ; Šlezingr, Jan (referee) ; Macháček, Jan (advisor)
This bachelor thesis aims to analyse the physical theory behind the photovoltaic cells and propose extension measurements for a modernised on-line laboratory. The first part of this thesis describes the theory of the photovoltaic conversion of solar energy into electricity. The p-n junction is described in detail because of its importance for a thorough understanding of the subject. The temperature dependence of a photovoltaic panel, i.e. the negative impact of rising temperature on the output power, is also described here. The contributions of this thesis include a summary of the current situation and the system of state subsidies for the current year as well as a proposal for an extension of measurements in an on-line laboratory, which is to be modernised, at the Department of Power Engineering. Therefore, the thesis includes some specific proposals of graphic dependence, which have a significant information value, and a possible further extension of the laboratory with new measuring and measured elements, which would be helpful for deeper understanding of the subject. In particular, it would be useful for understanding which factors influence the output power of a photovoltaic panel, both significantly and less significantly, which is undoubtedly the most important point.

Thermo-electric solar generator
Kočvárek, Ondřej ; Jakubová, Ivana (referee) ; Gregor, Jan (advisor)
The introduction of this work is devoted to the description of physical principals and condtruction of modern semiconductor thermoelectric transformers. This work describes thein basic characters and the most commonly used materials for thein production. Further, it mentions the basic principals and physical effects that describe the thermoelectric conversion of energy and the nondestructive method for establishing the basic material characteristics of thermoelectric transformers. The substantiv part of this work is the measuring of the material’s characteristics of the accessible thermoelectric elements through the medium of experimental measuring network. The optimal construction of thermoelectric solar generators used for individual thermoelectric elements are designed based on the taken measurements and the evaluation of material’s characteristics of the observed thermoelectric elements.

The assessment of connectivity 138 MW combined heat and power plant in Prostějov
Vacek, Tomáš ; Opat, Jaroslav (referee) ; Bátora, Branislav (advisor)
The goal of this project is to test the possibility to connect the Cogenerational generation of power 138 MW (still in the development stage) to the control room 110 kV in Prostejov production. This merge would product the electrical energy as well as the heat energy for all local area. In this dissertation we will be considering the solution of the steady state (stationary state) of system with the voltage level of 110kV, as well as the influence of the generation of power on this system, there by the suggesting a connection. The Congenerational production indicates higher effectiveness in the transformation of energy during primary production process due to the production of heat energy as well as the electrical energy from the primary power sources. In our country, as well as around the world, commonly used fuels are fossil fuels- coal, crude oil, and gas. As the demand for energy grows, those supplies are slowly running out. Not to mention that those fuels have a negative environmental impact. They are a source of carbon, which causes damage to the atmosphere and leads to global warming. Power plants which do not produce carbon are much safer for the environment, and much more productive. However, the residue of this energy is challenging to dispose of. Nuclear energy has common attributes with renewing the sources of energies that are extremely friendly to our environment. Nuclear power plants also produce enough energy and with the usage of Fourth generation reactors, they will be able to recycle the nuclear fuels. Today, more importance is put on renewing sources which are more gentle for the environment. In the near future, CEZ Company, the largest producer of electric energy is planning to use water energy. Water energy comes from water plants or dams. Other ecological forms of energy include geothermal and solar energies. These two types of energy are not as applicable for our geographical position. Geothermal energy is commonly used on islands where there is an abundance of natural hot springs. The most discussed source of energy is bioenergy. It uses natural wood sources, recycled wood products, and applies bioenergy as a main source for thermal power plants.

Control of decentralized energy sources and storage systems
Maksimovich, Valeriia ; Wannous, Kinan Hasan Wafaa (referee) ; Šedrlová, Magdalena (advisor)
Žijeme ve století, ve kterém jen těžko dovedeme představit život bez elektrické energie. Vznikajicí malé elektrárny, které vyrábějí elektřinu z obnovitelných zdrojů energie vyvolali potřebu v přisnějším řizení, inteligentním měření a změny Evropského trhu s elektřinou. Hlavní otázka spočívá v tom, jak zajistit spolehlivé, bezpečné a udržitelné dodávky energie a současně minimalizovat náklady a znečištění životního prostředí. Jedním ze způsobů je integrace decentralizovaných zdrojů energie do sítě. Tato práce se zabývá konceptem decentralizované výroby energie, paralelním provozem s distribuční sítí, akumulací a pokročilými způsoby řízení zdrojů. Práce také poskytuje přehled účastníků trhu s energií, jako jsou napřiklad obchodníci s elektrickou energií, agregátoři a lokakní distribuční soustavy.
