Design for a photovoltaic plant on the roof of a house
Kattauer, Jakub ; Haluza, Miroslav (referee) ; Pěcha, Jiří (advisor)
This bachelor thesis is focused on the issues of the fotovoltaic-electricity which is situated on the rooftop of the family house. The first part of this thesis deals with a solar radiation in the region of the Czech republic, photovoltaic conversion and electric attributes of solar cells. In the following part is analysed current status of an available technology of a sollar cells. The next topic which you can deal with is a process of the manufacturing of solar cells, basic selection and partition of inverters, construction and with the manufacture of the several kinds of connection. The next chapter is about to explain how you can gain an aid of the state from the bottom to the nowadays. The last part of this thesis is dedicated to a specific proposal of the fotovoltaic factory on the rooftop, calculation of an investments that are need to be paid and enumeration of a possible financial return.

The Effect of Accumulation on Distribution Grid Operation
Jestřáb, Tomáš ; Černý, Pavel (referee) ; Toman, Petr (advisor)
This diploma thesis introduces the reader to the possible types of electric energy storage technologies, their comparisons and utilization. After its introduction, it follows the description of individual technologies and principles that are currently meaningful and useful in practice. The thesis continues with the part characterizing the ways of using the accumulation in the grid. However, the main points of this thesis include the analysis of the influence of the photovoltaic installation on the specified distribution grid operation at the low voltage level and the analysis of the influence on the grid with connected accumulation. Another important objective was the model for the calculation of steady-state, which was programmed on the basis of the theory supported by the principles of production from intermittent sources and the principle of accumulation function. The outputs of the model in the form of the calculated voltage ratios at the individual supply points and current flows at the distribution transformer point were used to evaluate the analyzes mentioned above. The courses of the calculated parameters are broken down by different scenarios (according to the period, the degree of integration of production and the accumulation or the power output of the production), graphically processed and compared from the point of view of voltage fluctuations and changes in the power (or current) balance of the supply transformer.
