The grid-off Wind Power, Principle, Effectiveness, Return
Havránek, Miroslav ; Radil, Lukáš (referee) ; Macháček, Jan (advisor)
This Master´s thesis deals with problematics of wind powered generators and their use in off-grid systems. In its first chapters aspects of wind as a power source are analyzed. Further on the thesis focuses on individual components of the off-grid systems. Also designing procedures of these systems are presented in the paper. The key parts of the thesis are 3 off-grid wind power system designs, which can be used to power a family house, and their energetical and economical evaluation.

Energy supply of mountain cottage
Flöhsler, Tomáš ; Martinec, Jiří (referee) ; Pospíšil, Jiří (advisor)
The aim of this Graduation Thesis is to devise a system of energy supply intended to provide supply of electric and heat energy to a vacation property. The main feature of this energy supply project stands for a shift from mains power supply to alternative energy supply using renewable resources. The reason for this change is the fustiness of power lines and their negative effect on the surrounding landscape. Due to the fact that authorities did not permit renovation of these power lines, the only way to preserve the functionality of the vacation property is to secure its power supply by employing renewable resources. The vacation property (a mountain cottage) is located in Hrubý Jeseník Mountains, approximately 15 kilometers from the town of Šumperk. The thesis also contains a description of the way outlying settlements are currently supplied with energy, including the possibility of accumulation and a brief description of each electrical appliance’s power consumption. In the design itself, I calculated the necessary collector surface and analyzed the most effective collector placement. As for the wind energy system, I had to found the best spot to place the turbine. Last but not least, the thesis contains the technical-economical comparison of the proposed alternatives.

Hydrogen as a promising energy carrier
Pinkas, Marek ; Brázdil, Marian (referee) ; Pospíšil, Jiří (advisor)
In recent years hydrogen has become an integral part of modern energetics. Although there are still many unresolved barriers and technological shortcomings in hydrogen energetics, its importance is expected to grow even more in the coming years. These facts were the motivation for writing this thesis. This bachelor thesis deals with hydrogen as a medium for energy storage and transmission as well as research about its properties, storage, production and use. In this thesis are described and compared various methods of long-term energy storage that are currently used. Presented are various traceable hydrogen pilot projects.

Power to gas
Abdallah, Hadi ; Lázničková, Ilona (referee) ; Radil, Lukáš (advisor)
Tato práce se zabývá problematikou technologie power-to-gas, která slouží k akumulaci energie tím, že přeměňuje přebytečnou elektrickou energii vyráběnou z obnovitelných zdrojů energie na syntetický zemní plyn. Cílem bylo představit aktuální trendy v oblasti power-to-gas a vytvořit model tohoto systému v OpenModelica. V práci jsou uvedeny všechny hlavní části systému power-to-gas: výroba elektrické energie, výroba vodíku elektrolýzou, zachycování a separace uhlíku, Sabatierova reakce a typy metanizace. Nejprve byl modelován denní průběh slunečního záření. Poté byl zpracován submodel přeměny záření na elektrickou energii pomocí FV panelů. Dále byl zpracován střídač DC/AC, distribuční cesta a měnič AC/DC pro napájení elektrolyzérů. Stěžejní částí práce bylo zpracování vlastní metanizační jednotky. Reakce je řešena pomocí van der Waalsovy rovnice reálných plynů. Podle toho je stanovena produkce metanu, který je poté skladován v nádržích. Dále se provádí simulace se dvěma cestami. Za prvé, energie získaná z fotovoltaické elektrárny je přímo vedena přes distribuční soustavu k elektrolyzérům. Za druhé, energie získaná z fotovoltaické elektrárny je přiváděna do 22 kV distribuční sítě, která pak napájí zbytek procesu. Závěrem práce je zhodnocení, které porovnává celkovou efektivitu systému vzhledem k power-to-gas vůči akumulátorovému úložišti energie.
