Financial return of home photovoltaic power plant
Jančík, Josef ; Malý, Milan (referee) ; Mauder, Tomáš (advisor)
This thesis if focused on return on ivestment evaluation of a photovoltaic system of residential house. The calculation is made for photovoltaic system with and without accumulation and in combination with other alternative source – heat pump. The costs of instalation and working of new systems are then compared between each other and with the cost of working of a current system without photvoltaic.

Pilot project on flexibility management at LV level
Sýkora, Jan ; Pilař, Martin (referee) ; Radil, Lukáš (advisor)
The thesis deals with the topic of flexibility, especially on the demand side. It includes the definition of terms related to the issue, the basic principles of operation and possibilities of use. The main researched branch of the study is the usage of the flexibility potential of heat pumps. The work is based on real data from a pilot project executed in the winter of 2021/22, which examines the portfolio of households with a heat pump and observes the possibilities of using flexibility, its management and especially the impact on load change depending on the estabilished baseline.

Preparation and characterization of unsaturated bio-polyester resins
Žůrek, Michal ; Petrůj, Jaroslav (referee) ; Figalla, Silvestr (advisor)
The theoretical part of this work is devoted to the selection of suitable components for synthesis of a branched oligoester and their structural arrangement. Further, oligomers of lactic acid esterified with crotonic acid branched by erythritol or pentaerythritol are discussed. Crosslinking of prepared oligoesters is accomplished by free radical mechanism using vinyl acetate as reactive diluent and 2,2'-azo-bis-isobutyronitrile as initiator. Resin was cured by vinyl acetate in different mass ratios. Results show that there in an optimal ratio for curing between oligoester and reactive diluent. Using less vinyl acetate results in insufficient crosslink density or, on the contrary, using considerable excess of vinyl acetate causes rapid polymerization, that also results in lower density of crosslinking. The crosslink density was determined indirectly by extraction of the soluble part to acetone after curing and drying of the product.

Proposal of measures in the low voltage network for the implementation of renewable sources and electromobility according to scenarios NAP SG
Vojtěch, Jan ; Kučera, Michal (referee) ; Ptáček, Michal (advisor)
The thesis analyzes legislative and strategic documents of the European Union and the Czech Republic which set targets in environment and energy area in 2030, alternatively in 2040. The individual chapter is dedicated to national action plans, where the most important is National Action Plan for Smart Grids setting specific requirements for future development of smart grids. The thesis contains analysis of distribution network in the municipality of Následovice and simplifying assumptions for the implementation of calculation. There are also introduced scenarios which have been used for the calculation of the distribution network with its results. Potential defects of the distribution network are commented with suggested solutions. The calculations were repeated to verify the solutions. Results are recapitulated in an individual chapter. Graphical outputs of the calculations can be found in the attachement.

Design and Realization of Mobile Photovoltaic Power Station
Lednický, Ján ; Morávek, Jan (referee) ; Baxant, Petr (advisor)
This diploma thesis entitled Design and realization of a mobile photovoltaic power plant is dividet into two parts. In the first, theoretical part one can learn about the state of representation of renewable energy sources in the field of electrical power engineering and about the structure of photovoltaic power station systems. The secont part of this thesis is focused on the own design and realization of the mobile photovoltaic power plant, on the selection of individual suitable components and ther dimensioning. In addition, a model of a mobile power plant has been created, on the basis of which the power plant was constructed. Finally, one can find a source code analysis of a power plant monitoring using a microcontroler

Microphotovoltaic systems
Nováček, Richard ; Jandová, Kristýna (referee) ; Vaněk, Jiří (advisor)
Master thesis deals with photovoltaic components and their principles. Evaluate the types of photovoltaic systems and their impact on the transmission system. The thesis deals with financial support to small and micro-photovoltaic systems, which can be used in terms of legislation of the Czech Republic. There are also described the changes in the amendment to the energy act and effect on the price of electricity in households. Compared with the domestic photovoltaic rest of the world and the view of the German energy concept. Part of the theoretical design of a hybrid photovoltaic plant, including the use of heat pump. Thesis deals with using hybrid photovoltaic plant and economic viability of the proposed system. The last part deals with the implementation of the proposed system and assesses the true value from those anticipated in the design.

Critical Analysis of EU Policy and Its Impact on Business of E.ON SE
Starostová, Andrea ; Kamenický, Oldřich (referee) ; Škapa, Stanislav (advisor)
Hlavným cieľom diplomovej práce je kriticky analyzovať politiku Európskej Únie a jej dopad na činnosť nadnárodnej spoločnosti E.ON. Keďže politika Európskej Únie má za cieľ zefektívniť spôsob podnikania vykonávaného v rámci Európskej Únie a okrem iného má predstavovať garanciu zodpovednosti jak spotrebiteľov, tak dodávateľov operujúcich na trhu, tak zámer práce bol definovaný na analýzu politického vplyvu rozhodnutí Európskej Únie a ich dopad na následné strategické rozhodnutia firmy. Analytická čas práce je preto zameraná na analýzu Európskej energetickej politiky s kladením dôrazu na profil spoločnosti E.ON, Európsku energetickú stratégiu, obnoviteľné zdroje, jadrovú energetiku, bezpečnosť energetickej dodávky a na Európsky systém obchodovania s emisiami.

Renewable energy sources in CR
Kozumplík, Ondřej ; Škvařil, Jan (referee) ; Fiedler, Jan (advisor)
The content of bachelor study is the technical recherche of the renewable resources of energy in the Czech republic. It appears here the principal, use, potential and advantages and disadvantages of each type of renewable resources - water, wind and biomass. Then the use of solar energy for photovoltaic conversion to electrical energy is described in detail. At the end of this study is described one of the many recently build photovoltaic power stations in the South Moravia territory, the solar power station in Bzenec.

Technology Power to X
Řezník, Dominik ; Baláš, Marek (referee) ; Kracík, Petr (advisor)
The bachelor thesis deals with technologies for the electricity storage based on its conversion into another form of energy ("Power to X"). It considers the possibility of their use for the storage of electricity generated by renewable energy sources, which should gradually replace conventional electricity production in coal-fired power plants. The first chapter of the thesis is devoted to the current and possible future state of the electricity sector in the Czech Republic and a description of selected electricity generation technologies. The second chapter contains a classification and description of technologies suitable for electricity storage – their functional principles, advantages and disadvantages or e.g. possibilities of further use of products obtained by means of conversions are included. In the third chapter, selected parameters of these technologies are illustratively compared in created graphs, each containing two parameters. The results of the comparison are then continuously discussed.
