Analysis of the renewable energy support schemes in the EU: Can be an ECOlogical also an ECOnomical?
Andoková, Senta ; Cahlík, Tomáš (advisor) ; Rečka, Lukáš (referee)
The study compares FIT (Feed-in tariff) and RPS (Renewable Portfolio Standard) as the two most commonly used support schemes for renewable energy sources (RES) in the EU. It examines a relationship of an Environmental Kuznets Curve (EKC) and by a practical experiment for public lighting in Prague the study proposes an ecological functioning of electricity grids in the EU with CO2 emissions reduction effect. The main contribution lies in the recency and originality of the econometric analysis and practical experiment. FIT and RPS analysis demonstrates that both schemes affect demand for electricity and increase its price. The econometric model was tested for 28 EU countries for 1990-2013. The results say that the EU is currently located on the downslope of the inverted U-shaped EKC with a turning point, after which the dependence begins to grow. Nevertheless, for the most of observations the turning point is too far to be a source of concern. Practical experiment has shown that installation of energy saving devices for electricity grids in the EU can bring satisfactory results in reducing CO2 emissions independently of state aid. More efficient use of existing energy sources, however, should rather serve as a complement to conventional support, phasing out with the development of RES technologies....

Optimization of Energy Flow During WWTP Operation - Smart Area Net
Pěcha, Jiří ; Máša, Vítězslav (referee) ; Braciník,, Peter (referee) ; Mastný, Petr (advisor)
The dissertation work deals with the issue of water treatment and possibilities of energy savings during the operation of sewage treatment plants. The aim of the work is to find the potential of alternative energy use, economical consumption, improvement of the facility system management and quality improvement of the wastewater treatment process. In the first part of the work, operating processes, energy flows and energy savings are discussed. To analyze the problematics, larger sewage treatment plants were chosen. Thanks to their size, it was easier to find critical points and test the usage of renewable sources in operation. After the energy audit, the individual processes were assessed and real operation pitfalls were determined. Further steps led to focusing on smaller facilities up to 2 000 PE. This step was carried out with the intention of preparing these plants for the planned legislative change and helping to create or modernize more energy-efficient solutions. Thanks to the establishment of consortium of Brno University of Technology, the Department of Electric Power Engineering and a company dealing with water treatment and automation control, a solution was created that modernize the electrical, automation and water treatment part of the plant operation. This innovative application was installed in the sewage treatment plant, where the issues were debugged, control algorithms were tested and the entire operation was launched in automatic mode. At the end of the wastewater treatment plant modernization, PV panels were installed on the roof, thus partially suppling the object with renewable energy.

Renewable energy sources support yesterday, today and tomorrow
Měsícová, Gabriela ; Pokorný, Jiří (advisor) ; Franková, Martina (referee)
Renewable energy sources support yesterday, today and tomorrow Abstract The diploma thesis deals with the issue of amendment to the Act on Supported Energy Sources 165/2012 Coll. It specifically focuses on the topic of auction mechanisms used as a tool for determining state aid. Over the past few years, these mechanisms have been successfully replacing the existing European renewable energy sources (RES) support systems and are also recommended by the European Commission, which considers them best option for the internal market. The thesis maps the historical development of RES support in Europe and consequently also in the national context, taking into account international commitments, and revealing the motivation for the reform of the existing system. It also focuses on the principles of auction mechanisms in theory, using in particular foreign literature, and monitors in particular approaches to providing pre-contractual certainty for both investors and the state, the way in which auctions are affected by the volumes of energy demanded or the lack of competition, as well as considering the advantages and disadvantages of each auction pricing approach. Consequently, the thesis follows the practical implementation of auctions in Germany and Poland, noting the specific mechanisms that these neighboring...

Influence of renewable energy sources on transmission networks in Central Europe
Málek, Jan ; Janda, Karel (advisor) ; Zeynalov, Ayaz (referee)
This thesis focuses on the influence of renewable energy sources on the transmission networks in Central Europe. Firstly, it gives an overview of the power and transmission systems of Central European states. Based on the analysis, three key causes of congestion and instability of the grid are identified. These include (i) insufficient transmission capacity between northern and southern Germany, (ii) Energiewende policy and (iii) existence of German-Austrian bidding zone. To assess the exact impact on the transmission grid, ELMOD model is employed. Two development scenarios for the year 2025 are evaluated on the basis of four representative weeks of the year 2015. The first scenario focuses on the effect of Energiewende on the transmission networks, the second one drops out nuclear phase-out and thus assesses isolated effect of increased solar and wind feed-in. The results indicate that higher feed-in of solar and wind power increases the exchange balance and total transport of electricity between TSO areas as well as the average load of lines and volatility of flows. Solar power is identified as a key contributor to the volatility increase, wind power is identified as a key loop-flow contributor. Eventually, it is concluded that German nuclear phase-out does not significantly exacerbate mentioned problems.

Coal-fired power plants: cheap electricity vs. clean environment
Krydl, Ondřej ; Loužek, Marek (advisor) ; Kozák, Jan (referee)
The aim of this thesis is to analyze the importance of coal-fired power plants on the market of electric energy, with emphasis on aspects that fundamentally affect their production. Coal-fired power plants belongs nowadays among socially unpopular source of electricity. In recent decades intensively growing interest groups that support state intervention and regulation of the energy sector. This is essentially a massive promotion of renewable energy sources at the expense of fossil fuel plants. Analysis of individual power sources shows that despite the current restrictive measures imposed on power plants burning fossil fuels, and especially coal-fired power plants, electricity produced from coal resources is still competitive, despite some drawbacks has many positive qualities. Coal-fired power plants produce higher amounts of greenhouse gases and other pollutants than other types of power plants. On the other hand, they are able to provide a stable supply of electricity to transmission network, and thus partially offset the high volatility of electricity supply from renewable energy sources. The price of electricity from coal-fired power plants could be considered as relatively low in comparison with other energy sources. The analysis shows that in terms of practical economic policy is not economically justified to reduce the proportion of coal-fired power plants in the total production of electricity.

Project of family farm as closed economic unit
Jakubčík, Václav ; Pazderů, Kateřina (advisor) ; Zdeněk, Zdeněk (referee)
The diploma thesis deals with the family farm, which deals with fast growing trees cultivation. Business plan for my firm is the operation of the cogeneration unit and ensuring its self-sufficiency. The intention is that the family farm should produce more than half the biomass for cogeneration units.
Diploma thesis works with providing services in processing of logging residues, removing seeding trees and transportation. All this in order to obtain sufficient quantities of the commodity for the operation of boiler plants with cogeneration unit. Further outputs are addressed including the use of waste heat. Necessary support in planning the boiler room is the SWOT analysis. Conclusion of SWOT analysis clearly support the business plan for hte operation of a family farm.
Another key factor, that motivates me to expand current boiler room is a continuously rising electricity price. I suppose part of the generated electric power will be used for wood drying, the rest of the energy power is supposed to be sold to CEZ. Revenue from electricity sales should improve my Cash-Flow.
An important source of energy is a waste hot water that will be used for heating lumber drying, rabbit slaughterhouses of Rabbit firm. The rest of hot water waste will be used for heating workshops and residential buildings around.
The main incentive for founding a family farm is request to have enough fuel for the cogeneration unit also in case of external source shortage. The target is to ensure fluent economic operation of whole technological equipment.
My target is an overall economic assessment of the project for extracting of biomass from various sources. After an overall assessment we got conclusion, that the project can be profitable especially due to own production. Services provided by my farm creates significant additional value.
For family farm founding motivates me also unemployment of several family members.
