Assessment of energy storage systems - Power to gas
Šojat, Filip ; Zlevorová, Tereza (referee) ; Baláš, Marek (advisor)
This bachelor's thesis is focuses on the issue of electrical energy storage using Power to Gas technology. The thesis is divided into two parts: a research part and a practical part. The research part provides a detailed description of the basic principles of Power to Gas technology, hydrogen production, and its potential applications in various fields. The practical part consists of a hypothetical study on obtaining electrical energy from solar panels and subsequently storing it as hydrogen. Various storage methods are compared.

Battery storage with second life cycle batteries
Král, Dominik ; Pazdera, Ivo (referee) ; Procházka, Petr (advisor)
The bachelor thesis deals with problems related to the solution of energy storage. It deals with the analysis of used types of accumulators, deals with their advantages, disadvantages, on what principle they work. It focuses on the possibilities and problems of using batteries in the "Second life" mode. It presents the subsequent process of preparing batteries for further application and defines the tests necessary to evaluate the condition of batteries before further use. Finally, the actual energy storage designs and the block topology of the energy storage are presented.

Predicting Use of Renewable Energy Sources in Local Distribution Network
Holcner, Oldřich ; Ing. Jan Zich, Ph.D., MBA (referee) ; Baxant, Petr (advisor)
The subject of the diploma thesis Predicting Use of Renewable Energy Sources in Local Distribution Network is to design a predictive model of consumption and production of photovoltaic power plants and verify these models with measured data. First, general theoretical and methodological points are outlined, acquainting readers especially with renewable energy sources and various methods of electricity storage. Then, the prediction models follows and their verification with real data sums everything up.

Use of solar energy for electromobility
Harant, Miroslav ; Morávek, Jan (referee) ; Marušinec, Jaromír (referee) ; Baxant, Petr (advisor)
The thesis deals with the use of solar energy for electromobility. First, the potential of electromobility on the current market is theoretically discussed. This issue includes mainly the producers of electrically powered vehicles, the issue of electric energy storage and the real applications of fast charging and photovoltaic charging stations. The second part of the diploma thesis deals with the measurement of electric car consumption and the evaluation of measurement results. In the next part, electric cars are analyzed, which use solar energy for their function and their efficiency is compared with the effiency of combustion engines. The main part of this thesis is the design of photovoltaic charging station for electric vehicles. The final part deals with the economic evaluation of the proposed charging station.

The Conversion Efficiency of Different Kinds of Energy into Electrical Energy and the Possibility of its Accumulation
Ostruška, Jan ; Bartošík, Tomáš (referee) ; Macháček, Jan (advisor)
The thesis deals with the issues of the conversion efficiency of different kinds of energy into electric energy. Firstly, the thesis presents a brief introduction into types of energy sources and their capacity. Then, conversion efficiency of particular direct and indirect conversion is scrutinized, pointing to factors which affect conversion efficiency. The next chapter deals with the possibilities of accumulating electric energy. These are analysed as far as conversion efficiency is concerned as well and the end of the chapter concludes with comparison of these particular possibilities. Booth parts of the process – power generation and its accumulation – are connected in comprehensive scheme of energy conversions. The thesis develops on this scheme by mathematic description of its components and by designing a simulation programme, which would show the flow of energy in the scheme.

Electric vehicles as energy storage element with renewable energy sources
Janečka, Jaromír ; Horák,, Bohumil (referee) ; Baxant, Petr (advisor)
This master thesis summarizes history of electric vehicles from its inception to present. Vehicles are divided into three groups according to the type of drive, special attention is paid to electric vehicles. Furthermore, typical ways of electric energy storage are presented, especially in the form of electrochemical cells, which are used in electric vehicles. The thesis also describes the situation of electromobility in the Czech Republic, namely government support, distribution companies tariffs, charging infrastructure and available electric vehicles. Finally, the concept of connecting electric vehicles to renewable energy source is described, with financial calculations for three profiled drivers.

Mathematical description of VRB battery
Korniak, Daniel ; Mastný, Petr (referee) ; Radil, Lukáš (advisor)
This work is in the introduction focused on the introduction of technologies for electrical energy storage, their description and capturing the main advantages and disadvantages. After this capture follows comparison of the various technologies in terms of efficiency , discharge time and the price for1 kWh . Following section focuses on electrochemical model VRB batteries , which describes the equations describing the behavior of a battery depending on the chemical an electrical properties . In the penultimate chapter, I introduced the language of object- oriented modeling language Modelica and the most common programs based on it, including a short introduction for modeling in MathModelica. The last part deals with the modeling of specific VRB battery, which we have at the faculty.
