Support of the energy sources construction for households
Stručovský, Aleš ; Radil, Lukáš (referee) ; Bartošík, Tomáš (advisor)
This bachelor thesis deals with the comparison of energy sources used for residential construction. It focuses on photovoltaic power plants, wind power plants, hydropower plants and cogeneration units. Budget cost of energy source is limited to the amount of 550 000 CZK. Every source of energy is defined by its feature, operating principle, advantages and disadvantages. Options of selling the produced energy and its price are specified. Furthermore, the particular building licence applications (construction administration approval, generation of power questionnaire, application for connection to the distribution network, application for the contract of energy production support) including all the necessary enclosures have been analysed. Essential aspect for buying the energy source is its power and it is chosen according to the type of source. Energy source of hydropower systems is flow and gradient, in wind power systems it is wind speed, in photovoltaic power systems it is sufficient intensity of sunshine and in cogeneration units its dependance on annual heat consumption. Specific energy source available on our market is chosen for every group and the calculations of annual electricity production, period of repayment and profitability in 20-year running period are performed.

Cogeneration power plant
Ptáček, Martin ; Pospíšil, Jiří (referee) ; Fiedler, Jan (advisor)
This bachelor thesis deals with heat and power supply of the family house, which uses natural gas.The first part reveals cogeneration technology in general, especially cogeneration unit based on gas-engine (internal combustion engine).In the second part, the thesis focuses on energy budget (power-balance sheet) issue. Finally, the third and fourth chapter, deal with particular calculation of usability of cogeneration unit in the small family house. Due to a small final financial difference and large investment costs, with such a low heat and power consumption, this technology is unsuitable for this type of usage.

Use of Cogeneration in Family Houses
Pusztai, Radek ; Mastný, Petr (referee) ; Baxant, Petr (advisor)
In the first part of the thesis is elaborated a general view on the issue of cogeneration - a joint production of heat and electricity. In addition to technical and economic aspects are also mentioned basic modes of operation of cogeneration units. Furthermore, installation conditions in the family house and legislative acts associated with the operation. The next section describes the technical parameters of the unit - TEDOM T7. Subsequently, the work performed calculations of the energy needs of the family house. In the next part there is an economic calculation of the object with reference to other sources of heat.

„Smart cities“ and decentralized production of energy
Opátová, Alexandra ; Kudela, Libor (referee) ; Špiláček, Michal (advisor)
This bachelor thesis describes the principles of decentralized energy sources, together with the advantages or challenges that concern the problem. The first chapter describes the concept of "smart city" and the field of use. There are also described options for modeling of urban areas as a unit. The second chapter focuses on the concept of decentralized power generation and the benefits that such a system can offer. The following chapters deal with cogeneration units and electricity storage options. The last chapter focuses on a issue of integrating decentralized power generation into the grid and compares various mathematical models and possibilities of regulation.

Biomass utilization for cogeneration small power
Neminář, Štěpán ; Škorpík, Jiří (referee) ; Baláš, Marek (advisor)
The subject of this thesis is the utilization of biomass for cogeneration units of small power (to 500 kWe). Within the first paragraphs the thesis focuses on technologies which produce more valuable fuels than the solid biomass. This chapter also describes the most recent processes of waste biomass usage. The following section summarizes gaseous and liquid products of this procedure and their feasible use in co-generation. In the last part of this thesis author describes a CHP devices which are used in small electric power production and assesses their advantages and disadvantages. Consequently, some options of their practical usage are highlighted. As a conclusion, these devices are compared and their possible future application is illustrated.

Cogeneration
Martinek, Jan ; Šnajdárek, Ladislav (referee) ; Fortelný, Zdeněk (advisor)
This bachelor thesis is intended to handle the issue of cogeneration. There is presented the principle of cogeneration and its benefits. Cogeneration is compared to the separate production of power and heat. This work deals with the storage of electric energy and heat and also deals with used batteries. The next chapter discusses the impact of cogeneration to environment and at the end there are mentioned the main Brno’s cogeneration units and central heat distribution in Brno.

Energy Assessment of Cogeneration and a Gas Boiler room
Kandl, Petr ; Počinková, Marcela (referee) ; Horák, Petr (advisor)
The thesis contains a gas boiler room energy assessment in Lišov. In the mentioned boiler room, there are instaled gas condensing boilers and cogeneration units Theoretical part of the thesis lists a summary of generally used cogeneration equipment and ordinarily used gases. Calculation part includes four variants of the boiler room reconstruction. Energy assessment compares the chosen variant from the calculation part with the original condition of the boiler room.
