Business Plan
Vinca, Martin ; Bartoš, Josef (referee) ; Veselý, Josef (advisor)
This bachelor’s degrese thesis help to explain the situation of setting up a small photovoltaic power plant in the Czech Republic. In the theoretical part of this thesis we are talking about necessary theoretical basises of setting up a small business. In the analytical part are the SLEPT analysis and SWOT analysis. These two parts serve as a base for the practical part. In the practical part is brought closer look on steps which need to be taken while establishing a photovoltaic power plant and is draw up a business plan.

Modeling and simulation of a hybrid micro grid in PSCAD environment
Moravčík, Martin ; Mastný, Petr (referee) ; Drápela, Jiří (advisor)
In the opening part of this master´s thesis there is given concept, description, usage and advantages of micro hybrid grids in comparison to micro grids and there are evolution steps towards hybrid grid. There is also a mention about economics of operation of these grids. In the second part of this thesis there are descriptions of devices that are suitable for usage in micro hybrid grids with emphasis on generators and accumulation possibilities. In the next part of this thesis there is given an approach and description for modeling of various components of hybrid grids in PSCAD environment. In the next part of this thesis there are given simulation results that were conducted on created model. Especially power balance in 24 hour operation of the grid with method for determining suitable size of accumulation and installed capacity of photovoltaics. And next there are showed responses from change of power from photovoltaics, next there is a transition to islanded mode and last there is showed the behavior of converter when the limits of accumulation are reached. In the final part of this thesis there are conclusions, fulfillment of goals of this thesis and possibilities of further study.

Risks and Impacts of Black-out in Czech Republic
Tomášková, Kateřina ; Poláčik, Ján (referee) ; Lisý, Martin (advisor)
Electricity is an integral part of our daily life. Only a small problem in the power system and a small current outflow can cause us a lot of inconvenience, let alone a wider outflow of elektricity. The aim of this thesis is to define the risks of black-out for the Czech republic. Then perform resers of foreign experience with the black-out and on the base of these experiances, outline the possible impacts for the Czech republic, in case that this situation would occur once in our country.

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.

Energy use of agropellets
Zahnaš, Ladislav ; Lisý, Martin (referee) ; Baláš, Marek (advisor)
This thesis deals with energetical use of agropellets made from agricultural residues especially in the terms of compliance with emission limits. First part is brief research of biomass in general and about methods of its processing. Second part deals with emissions from agropellets combustion and third part consists of an experiment where several types of pellets were burned, and their emissions evaluated.

Mobile photovoltaic power plant
Klíč, Tomáš ; Morávek, Jan (referee) ; Baxant, Petr (advisor)
This diploma thesis is divided into two parts, namely the theoretical and practical part. In the theoretical part, the issue is dismantled from the current state of electric power, share the production of individual sources, the market for photovoltaic and mobile photovoltaic systems through the description of the theory of solar radiation and all the necessary components to build the isolated photovoltaic power plant. The practical part deals with dimensioning, selection of suitable components and the actual one own design and implementation of a mobile photovoltaic power plant.

Energy saving of large objects
Řehák, Pavel ; Brázdil, Marian (referee) ; Pospíšil, Jiří (advisor)
The aim of this diploma thesis is to evaluate the economical measures using own heat and power production using cogeneration units, use of renewable resources to partially cover the consumption of objects, reduction of thermal losses by evaporation in the outdoor swimming pool and overall increase of waste heat utilization by exchanger heat exchangers from flue gas and heat from waste water.

Heating and ventilation in a renovated family home
Nejerál, Michal ; Hejčík, Jiří (referee) ; Charvát, Pavel (advisor)
The main goal of the diploma thesis is to design a new ventilation and heating system in an old house after its reconstruction. The design also includes consideration of the possibility of using renewable resources. A central heat recovery ventilation systém is designed to ensure ventilation of the building. The heating design is based on two independent heat sources. It is a wood boiler and a gas condensing boiler. After considering renewable sources, a photovoltaic system is designed. The results of individual calculations and drawing documentation of designs are also attached.

Wind power plant in a chosen locality
Dohnal, Petr ; Škorpík, Jiří (referee) ; Martinec, Jiří (advisor)
This master thesis deals with problematic wind power plants. There are described advantages and disadvantages of wind power plants and their environmental impacts. Thesis include chosen locality for wind power plant, chosen fitting types of turbines and calculation which choosing turbine for chosen locality. There are accomplished parametric studies of main parameters. From this study is chosen best fitting model of wind turbine. In the end are adduced statistics from Czech Republic, Europe and world.
