Evaluation of possibility of modifying selected part of public lighting network for EV charging
Hýsek, David ; Vrána, Michal (referee) ; Baxant, Petr (advisor)
The master thesis deals with the concept of smart cities in the context of motivation for the use of the synergy of public lighting network and charging points. The thesis provides an overview of projects from the Czech Republic and abroad focusing on the adaptation of the urban public lighting network for charging electric vehicles. Different variants of charging station installations and their management are discussed. Another important topic is the selection of a suitable location for charging stations and the concept of synergistic connection of these stations with the existing public lighting network. The thesis proposes scenarios for using the existing public lighting network for charging electric vehicles and scenarios for bringing a parallel cable to this network in selected Brno locations. The aim is to optimize the efficiency and performance of the public lighting network and at the same time provide a charging infrastructure for electric vehicles. The results of the thesis represent a valuable contribution to urban planning and the development of smart cities that focus on sustainable and environmentally friendly mobility. The synergy between the public lighting network and charging points represents a potential for efficient use of infrastructure in the urban environment while contributing to the reduction of greenhouse gas emissions.
Energy management of residential building with a photovoltaic system
Prášil, Kryštof ; Vrána, Michal (referee) ; Mastný, Petr (advisor)
This thesis deals with the evaluation of the electricity consumption of a family house with a photovoltaic power plant and electric heating. A control system was designed for this object, ensuring the optimization of consumption. The work summarizes the currently available options for power consumption management in buildings with photovoltaic plants. Subsequently, the thesis contains a description of the chosen management method. In the next part, the final algorithm of the control system is put together, which was preceded by operational testing and optimization. Finally, the thesis presents an evaluation of the energy and economic efficiency of the system.
Heat pump in cooperation with PV for family house
Drašar, Vojtěch ; Vrána, Michal (referee) ; Mastný, Petr (advisor)
The bachelor thesis deals with the design of a heat pump in cooperation with a photovoltaic system for a family house. The theoretical part describes the principles of the heat pump and the photovoltaic system. The thesis presents the methods of operation of the heat pump, the principles of building cooling, the connection of the PV system to the grid, or the methods of storing excess energy. In the practical part, the consumption of a typical family house has been determined by means of typical supply diagrams. The consumption is based on hourly statistical values for the year 2021. From the obtained values a pump was designed. Another objective of the work was the placement of photovoltaic panels on the roof. The power plant is considered as a hybrid, in order to maximize the consumption of the energy produced and the use of energy at the point of generation. For this, a battery system was also designed. The work includes an energy and economic evaluation, including the payback of the combination. For the economic evaluation, a subsidy from the New Green Savings 2021+ program was considered. The proposed solution has applications in both renovation and new construction, where the emphasis is on minimizing air pollutants and also the use of ecological resources.
Safety of off-grid hybrid energy system operation
Orság, Štěpán ; Vrána, Michal (referee) ; Morávek, Jan (advisor)
The thesis deals with the safety of hybrid systems in island operation. The safety requirements for electrical installation with photovoltaic system and protection against electric shock are discussed. Hybrid battery systems have a lower short-circuit performance in islanded operation, compared to parallel operation with the distribution grid, so the thesis focuses on the specifics of islanded operation and the use of protections that are part of the PV inverter or electrical installation. The work includes the design of test procedures and measurements on selected inverters with subsequent evaluation and recommendation of further protection measures.
Design of Loxone system installation control for a house with PV plant
Kořínek, Tomáš ; Vrána, Michal (referee) ; Bátora, Branislav (advisor)
This master's thesis deals with a management proposal of Loxone system installation for a family house with a photovoltaic power plant. The first part of thesis deals with the characteristics of the Loxone system and its individual devices. The second part is already focused on the design of the algorithm and the implementation of the lighting, shading, heating and indoor environment of the building control in the Loxone Config program.
Food as cultural and social phenomenon, ethics of dining - gastronomical world
Vrána, Michal ; Šmíd, Jan (advisor) ; Hanuš, Jiří (referee)
TITTLE: Food as cultural and social phenomenon, ethics of dining - gastronomical world. AUTHOR: Michal Vrána DEPARTMENT: Ústav profesního rozvoje pracovníků ve školství SUPERVISOR: PhDr. Jan Šmíd, Ph. D. ABSTRACT: In his thesis on "Food as a cultural and social phenomenon, ethics dining - gastronomic world" by dealing with the phenomenon of food in the context of broader socio-cultural and artistic fields. Introduce general views on food and gastronomy in different historical epochs and civilizations to the present. I will focus primarily on the depiction of "dining" and "stolovací" themes in art history and art production. I will mention the development of rules of etiquette, ritual feasts and social dining. The didactic part, carries out projects in the hour of art education in selected primary school.
Evaluation of advantages and disadvantages of aircraft automatic systems
Vrána, Michal ; Koštial, Rostislav (referee) ; Horpatzká, Michaela (advisor)
This bachelor’s thesis deals with civil airplane automatic systems. The first part analyses historical development of flight control systems and automatic system together with philosophy, which is implemented in modern airliners. In the next part, we evaluate advantages and disadvantages together with list and description of modern avionic systems, which participate on automatic flight. In the last part, selected airplane incidents and accidents are analysed, focusing on influence of automation with incidental human factor.
Connection of Solar Power Plant and Water management
Zajíček, Michal ; Vrána, Michal (referee) ; Baxant, Petr (advisor)
In the bachelor's thesis Connection of Solar Power Plant and Water management the author designs the technical solution of pump control using solar energy. The main reason is to make an automatic system for pumping the rainwater through filters due to increasing its quality. Powering the device with a solar power plant will reduce the energy requirements and will also make it possible to store surplus energy from the solar power plant into the potential energy of the water. The result of the work is the compact device with an automatic control system designed to control small 12 V pumps, theoretical design of the photovoltaic power plant to power the device and theoretical analysis of solar energy and water management issues.
Analysis of floating photovoltaic usage in the Czech Republic
Al Halabi, Enas ; Vrána, Michal (referee) ; Paar, Martin (advisor)
Tato práce se zabývá technologií plovoucí fotovoltaiky, její strukturou, komponenty, vhodnými vodními plochami, výhodami a výzvami. Dále poskytuje přehled na její historie plovoucích elektráren a jejich nasazení na světě. Je popsáno základní hodnocení umístění pro instalaci FPV. Jako hodnocený vodní plocha byla vybrána vodní nádrž Nové Mlýny, v této lokalitě byl navržen a popsán plovoucí FV systém. V této studii je zmíněna srovnávací analýza s cílem porovnat konstrukci, náklady, provozní prostředí a výrobu elektrické energie plovoucího a pozemního fotovoltaického systému.
