Energy use of digestate
Kaška, Zdeněk ; Štelcl, Otakar (referee) ; Baláš, Marek (advisor)
This bachelor thesis deals with the research of biomass in general, its types and processing. Nowadays, biomass appears to be an environmentally and financially acceptable substitute for fossil fuels due to increasingly stringent emissions standards. The second part deals with its particular type, digestate. It is investigated whether the fossil fuel can be replaced or how the energy production process could be changed.

Control and monitoring of a distributed energy generation systems based on renewable sources with storage system
Smugala, Ondrej ; Paar, Martin (referee) ; Vrána, Michal (advisor)
The diploma thesis is dealing with possible approaches to control distributed energy resources and storage systems. One of these approaches is a virtual power plant and its concept is described in the first part of the thesis. The virtual power plant is a controlled system of distributed energy resources, storage systems and controllable loads interconnected via communication network, that can act as a conventional power plant. The theoretical part contains a survey of control system's topologies, a brief summary of available communication infrastructures and standards. The second part of the thesis is focused on the description of operation and control of hybrid system that represents an inseparable component of virtual power plant. A Matlab Simulink model was created for this purpose. A simulation of hybrid inverter's step response is realised to test the operation of the hybrid system and it is compared with the real measurements in the laboratory. A comparison of control approaches of hybrid system implemented on the basis of measurements is also included in this thesis and was published in the scientific paper attached in the appendix.

Wind power plant in area North Moravia
Pasírbková, Adéla ; Zmeškal, Oldřich (referee) ; Kotlík, Josef (advisor)
This thesis deals with analysis of wind parks from aspect of EIA, the annual capacity factor and the economy of operation. It shows the utilization of wind power in wind plants, wind potential of the Czech Republic and criteria for selection locations for construction wind plant. It describes the Act No. 100/2001 Coll., on environmental impact assessment, in which is the EIA process regulated. It analyses potential and real possibilities of wind power utilization in the North Moravian Region in connection with the Territorial Energy Policy.

Off-grid street lamp design.
Hampl, Petr ; Karásek, David (referee) ; Křenek, Ladislav (advisor)
Oblast problémů, ze kterých konkrétní téma projektu vychází, zahrnuje současnou globální transformaci zdrojů energie a jejich dodávek se zvláštní pozorností na obnovitelné zdroje energie. Důraz je kladen zejména na hodnoty jež přináší produkt určený k užívání ve veřejných prostorách. Autorovým zadáním bylo navrhnout osvětlovací jednotku nezávislou na vnějším zdroji napájení. Cílem návrhu je přehodnotit způsob, jakým jsou dnes technologie využívání sluneční a větrné energie běžně používány, a navrhnout řešení přinášející nové vlastnosti a užitné hodnoty pro přímého uživatele i celou společnost. Autor přináší návrh produktu jenž je reakcí na současné globální hrozby a příležitosti. Výsledkem projektu je návrh pouliční lampy kombinující fotovoltaický článek a větrnou turbínu s cílem získat elektrickou energii jež je dočasně akumulována a následně dodávána svítidlu. V návrhu je kladen důraz na požadavky ergonomie a estetickou hodnotu produktu. Navržené řešení znamená finanční přínos z hlediska šetření neobnovitelnými zdroji energie a případnými finančními výhodami pro investora plynoucími z provozování veřejného osvětlení. Pouliční lampa nezávislá na vnějším zdroji napájení má navíc menší negativní dopad na životní prostředí a představuje technologie využívání větrné a solární energie v přívětivé a nerušivé podobě.

Energy, economic and environmental analysis of balneotherapy
Miček, Denis ; Horák, Petr (referee) ; Hirš, Jiří (advisor)
The aim of this diploma thesis is to point out European Union´s goals such as low carbon economy, mainly future increasing the use of renewable sources as a potential source of energy. Slovak republic has due to its position in central Europe, rich in natural healing sources of water, which are considered as the most perspective sources of renewable energy in this country. The problem was solved as energy, economic and environmental analysis of Balneotherapy at Slovak Heath Spa Piešťany a.s. This analyzation was provided by real experimental measurement of temperature and flow rate and computational simulation of technological devices in opened natural healing water system. Experimentally measured data were afterwards use for elaboration conceptual design of new technological devices in order to increase efficiency of collection energy from potential renewable source of energy. The research shows that with help of new design technological devices connected to existing ones will be possible to cool down temperature of hot natural healing water from 67 °C to 21 °C, which decrease operation costs of Balneotherapy for more than 1 414 € per day. By Slovak republic entering to European Union it was necessary to accept global goals of low carbon economy. This diploma thesis provides an attention on potential energy in natural healing sources of water as renewable source of energy and helps Slovak Health Spa Piešťany to decrease amount of green-house gases released to atmosphere by efficient increasing the use of energy potential in natural healing source of water.

Electric boiler connection in heat plant for providing ancillary services
Ditrych, Marek ; Příhoda, Martin (referee) ; Wasserbauer, Vojtěch (advisor)
The bachelor thesis deals with using the electric boiler for extension ancillary services in heating plant. The system and support services are described in the thesis, because the ancillary services regulate an energy deflection. The system and ancillary services are described in the thesis. Thanks to these services an energy deflection is regulated. The thesis describes different types of electric boilers and there functions. In the thesis is shown the possible solution of using an electric boiler in heating plant Opatovice. The cable conduction is designed for a power of electric boiler. For this reason, there is calculated the equivalent warming short-circuit current close to the electric boiler.
