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.

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.

Uninterruptible Power Supply
Mrázek, Petr ; Harabiš, Vratislav (referee) ; Sekora, Jiří (advisor)
The thesis deals with Uninterruptible Power Supply (UPS) and associated problems of backup power in case of unexpected outages of electricity. Start of work is dedicated to limitation of the electricity supplies, as well as their causes and consequences. Furthermore, brief history of UPS and subsequently distinguish between UPS’s architectures. There is also a description of the energy sources such as batteries, flywheels or fuel cells. Part of thesis describes security of electricity supply in health care facilities, including requirements for emergency power. The own design of UPS is described in the end.

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.

The Application of an Innovative Methodology for Transmission System Development Planning
Vrábel, Radek ; Pistora, Martin (referee) ; Toman, Petr (advisor)
This master thesis deals with new approach to development planning in transmission system. As an introduction to the topic the current ways of planning the development of the transmission system are presented in the beginning of the theoretical part of the thesis. The following section analyze the projected scenarios of the development of energy sector from three different sources. The theoretical part is followed by modelling of the electricity market with an explanation of its use for planning the development of the transmission system. The next chapter deals with the use of market modelling results in the network calculation of steady state with and without contingency. The last part of the master thesis analyzes the results of the simulations and proposes appropriate steps and new projects.

Analysis of Using Cable Sections in the Route of 400 kV Overhead Line
Belatka, Martin ; Rusek, Stanislav (referee) ; Modlitba, Petr (referee) ; Matoušek, Antonín (advisor)
The thesis deals with the use of cable sections in the overhead transmission route of the 400 kV transmission system in the Czech Republic, with the design of the arrangement of the cable route and with the solution of the crossover of the cable line with other networks of the technical infrastructure or natural obstacles. The thesis shows what the construction of a 400 kV cable line in the overhead transmission route - which has not been implemented in the Czech Republic as of yet - entails in practice. The first, general part deals with the electrical properties of both the cable lines and the combined overhead transmission lines with intermediate cable sections, and this sets out limitations on the maximum possible length of the cable sections. The following chapters provide an analysis of the magnetic field of the cable line, its impact on the surrounding environment and the possibilities of its shielding. On the basis of this knowledge optimization of the designed cable route arrangement is carried out in order to make the route comply with hygiene limits. The next part uses selected locations on a real route of overhead 400 kV transmission line to show what the construction of cable sections inserted into the route of overhead 400 kV line would involve. The design includes a professional estimate of the time and financial demands of the construction.
