Potential of non-frequency ancillary services for a distribution system operator
Reiskup, Filip ; Holub, Martin (referee) ; Ptáček, Michal (advisor)
This thesis provides a basic overview of the ancillary services in a transmission system. It summarizes changes regarding the implementation of European directives SOGL and EBGL. It describes in detail a portfolio of non-frequency ancillary services used in the distribution systems. It evaluates the demand of E.ON distribution system potential for those services in particular locations. Practical part is focused on a potential of reactive power management in this distribution area. It evaluates reactive power flow into transmission system and indicates the most critical substations. This thesis also covers analysis of existing resources in this distribution area and assign their possible potential in reactive power management.

The Impact of Media on Consumer Behaviour in the Energy Sector
Sedláček, Štěpán ; Hála, Tomáš (referee) ; Langerová, Petra (referee) ; Šedrlová, Magdalena (advisor)
This bachelor thesis deals with the analysis of the aspects that prevent or allow the integration of the principles of social networks into the system of smart meters as well as the study of their potential and possibilities of implementation. The issue of how the future smart grid consumer will benefit from the future smart city grid services are hot topics. Here, a survey is presented that focuses on these aspects. An analysis of the survey results and key messages identifies view of the people on the topic and proposes directions that may be followed when designing applications and services of residential smart city consumers.

Data transmission over the distribution network
Mucha, Martin ; Mrákava, Petr (referee) ; Mlýnek, Petr (advisor)
his paper describes the principle of data communication through high-tension lines.Preliminary work examines the transmission system, the types of high-tensionn lines and then disassembling the possibility to transmit data through this system. Then there is interference with the types of data and analysis. It includes the PLC technology, which include types of modulation and error correction methods. The paper deals with the possibilities of PLC modems and their use. The following chapter defines the ways of modeling the high-tensionn lines through which is possible to deduce the transfer function of lines. The work includes practical examples of setting the PLC modems and data transmission from one modem to another. It shall also include practical demonstration of spectrum communication signal during the data transfer.

Leakage of information through active and passive elements in optical fibre infrastructures
Spurný, Vladimír ; Horváth, Tomáš (referee) ; Münster, Petr (advisor)
This bachelor thesis deals with the problem of information leakage from optical fiber infrastructures, both from the fibers themselves and from passive and active elements. The first part is devoted to a theoretical description of the transmission of information over an optical fiber and the function of individual components. The next part is focused on the theoretical analysis of possible information leaks. In the last - practical part, there will be an examination of some of the previously described possibilities of information leakage with subsequent analysis and a proposal for risk minimization.

Gas - steam cycle
Tóth, Richard ; Špiláček, Michal (referee) ; Kracík, Petr (advisor)
The Bachelor thesis „Gas-steam cycle“ explains the cycle from technical point and then its application in economic terms. At the beginning is explaind how gas turbine work and its application in Czech republic and World. In practical part are for real Gas-steam cycle Power Plant in simplified way calculated basic parameters and efficiency in full operation and operating only with gas turbines. The end contains a design of Heat recovery steam generator.

Design Of The Overhead Line Section Of The Transmission System
Reiskup, Filip
This paper describes a basic summary about the transmission and distribution systems and their overhead lines in Czech Republic. In detail it also describes area around Ústí nad Labem which is very technically interesting for the design and the calculation of the overhead lines at voltage level of 400 kV. Therefore, the paper gives the proposals of the most suitable solution how to connect significant power energy source to the transmission system.

Dynamic loading of overhead lines
Šimák, Josef ; Jurák, Viktor (referee) ; Orságová, Jaroslava (advisor)
The bachelor's thesis is focused on the introduction of equipment and principles in dynamic current loading of lines. The individual methods are introduced and described with a focus on online monitoring systems. Furthermore, the calculation of the dependence of the parameters of AlFe conductors on the temperature change is performed.
