Energy independence and optimization of energy consumption with use renewable sources and smart wiring in house
Kaděra, Jan ; Hošek, Milan (referee) ; Bátora, Branislav (advisor)
This bachelor’s thesis focuses on optimization of electric energy consumption in household and its energetic independence. There is an overview of available energy sources for household and possibilities of its accumulation. Next, the function of system electrical wiring is described and compared with systems in today‘s market. In more detail, the thesis deals with description of FOXTROT control system developed by the company TECO a. s. and with possibilities of its application. The study describes savings optimization from both investment and operation perspective. A comparison of appliances of two energy classes in current prices is done, as well as a comparison of one-way and two-way pricing. Savings opportunities in lighting system, temperature control and appliance division according to their manageability are demonstrated. A calculator for photovoltaic system was created which provides return time of investment upon input parameters. A part of the thesis is a project documentation realized as a stage of a household object study, on which optimization opportunities are demonstrated.

Super Grids Conception
Chodura, Przemysław ; Prokop, Václav (referee) ; Paar, Martin (advisor)
Cílem bakalářské práce “Super Grids Conception” je poskytnout komplexní náhled na problematiku Super Gridů ve smyslu pozadí, konceptu jako takového, dostupných technologií, dosavadních zkušeností a budoucího vývoje, možných zdrojů elektrické energie a konkrétních konceptů a studií. V úvodu jsou osvětleny důvody vedoucí k potřebě elektrických sítí nové generace – celosvětové snahy snižovat dopad výroby elektrické energie na životní prostředí, rostoucí poptávka po elektrické energii a potřeba integrovat obnovitelné zdroje energie. Možné zdroje elektrické energie jsou diskutovány jak v širším kontextu, tak i ve smyslu současných omezení a budoucího vývoje. V druhé části jsou popsány koncepty Smart Gridu, Super Gridu a SuperSmart Gridu s důrazem na přínosy, základní principy a systémové hledisko. Autor se dále zabývá jen koncepcí Super Gridu. Použití stejnosměrných (HVDC) a střídavých (HVAC) technologií je porovnáno z technického i ekonomického hlediska a z něj vycházející typické použití těchto technologií. Dále je podrobně popsána nejlepší dostupná technologie HVDC systémů – základní principy a konfigurace, popis jednotlivých částí, omezení současných technologií, dosavadní zkušenosti a možný prostor pro další vývoj. Následuje zmínka nových výzev oblasti HVAC technologií ve vztahu k Super Gridům a popis problémů souvisejících s hybridními AC/DC linkami a koridory. V poslední části jsou vysvětleny rozdíly v historickém vývoji a současných postojích v různých částech světa. Zároveň jsou představeny koncepce zvažovaných Super Gridů. Zvláštní prostor je poskytnut vizionářské koncepci vytvořené DESERTEC Foundation a technickoekonomické studii OffshoreGrid.

Hydro power station design
Novák, Pavel ; Grepl, Robert (referee) ; Ondrůšek, Čestmír (advisor)
This thesis deals with designing a small hydraulic power plant, where a swirl turbine is conected to a unique synchronous working, which will offer a reliable and easy installation of the hydraulic power plant. As a result a wider potential of energy could be produced from renewable resources. The use of a narrow rottor as a holder of the permanent magnets is the biggest difficulties of this design.

Uninterruptible power supply
Podal, Pavel ; Rampl, Ivan (referee) ; Chmelař, Milan (advisor)
The objective of this work is to inform readers on classification of Uninterruptible Power Supply (UPS). depending on the equipment for which is to be used. Voltage quality has a decisive influence on the operation of equipment. There are various common power problems that UPS units are used to eliminate. Furthermore, I described backup power sources of energy used for UPS, in partikular secondary battery. This text is about UPS technology used for critical applications, witch must not fail due to a power outage or other power anomalies too.

Business Plan
Bureš, Ondřej ; Polák, Michal (referee) ; Pernica, Martin (advisor)
This diploma thesis deals with harvesting electrical power from renewable resources - natural raw materials, specifically from biomass, by means of energy producing equipment - biogas station. Theoretical part is focused on possibilities of energy production from renewable resources, analysis of administrative measures connected both with power engineering legislature and limited company establishing. It deals with procedures necessary for implementation of the plan and funding possibilities - grants and long term bank loans. Following analytical part is aimed to particular identification of surroundings, chances and risks connected with proposed design. Prospectus with the objective of establishing limited company BS Cerekvice nad Loučnou, s.r.o. is described in the project; this company will be focused on construction and operation of biogas station, producing electric power and heat.

Conditions of Waste-made Fuel Combustion including legislative Requirement
Matoušek, Petr ; Pavlas, Martin (referee) ; Novotný, Pavel (advisor)
This bachelor’s thesis describes possibilities of usage of waste-made fuel from point of view of energetic utilisation in industry and power supply. There is a brief overview of energy resources structure, current situation in energy production and in waste management in Czech Republic. Particular types of waste-made fuels are also specified. One of the main parts of this work is fundamental analysis of legislation which governs waste management and alternative fuel usage. In the last part of the thesis the possibility of usage of mechanical-biological treatment as a waste management system is assessed.
