Intelligent control of the storage water heater
Vašica, Radoslav ; Macháček, Jan (referee) ; Šlezingr, Jan (advisor)
The work generally deals with the possibilities of preparing hot water in household and analyzes saving posibilities. At the beginning of work the history of hot water preparation is briefly indicated. Chapter 3 deals with different ways of heating. Described in more detail electric storage heating is in chapter 4, where can be found the effect of heating to the power network, especially to the daily load diagram. The following are the information of the tariff policy, as a tool for motivation of consumers, for using the storage heating. In the next part, beginning with the fifth chapter, is written about the possibility of energy saving by means of intelligently controlled boiler. That eliminates the disadvantage of storage heating, which are the tank thermal losses. Heating is based on a certain regularity in the behaviour of the user and manages the preparation of water according to expected consumption. The sixth chapter then contains design of own algorithm for economical control of heating and also energetic and economic assessment of potential savings.

Study of Power Plant Connection to Power Network
Sýkora, Martin ; Kurfűrst, Jiří (referee) ; Paar, Martin (advisor)
It is necessary to judge the influences of producers on the electric compounds while creating electrical energy or during the regulation of those existing. These analyses are sorted out by so called studies of connectivity. These calculations analyze the degree of connection of the producer and the standby unit during a break-down. The results of this report are several recommendations for creating such unit and succeeding steps leading to secure the stability and safety of the electric compound operation. The aim of this thesis is to discuss about software for PC solutions for static and dynamic network model, to draft power outlet into a network of generating high voltage, to complete a study of connectivity with respect to all the distortion factor, as increased voltage, inrush current at startup, flicker, harmonic currents, interference ripple, contribution to short-circuit current, reactive power control options, and demands for compensation.

Analysis of Smart Grid devices
Kolacia, Tomáš ; Šlezingr, Jan (referee) ; Radil, Lukáš (advisor)
This work deals with smart grids and smart metering in power grids. The first part of the thesis is focused on the comparison between classic topology of electrical grid and smart grid concept including the benefits, which could be achieved. The other parts of smart grid concept are described as well, such as energy storage and electromobility including charging points infrastructure. The second part of the thesis deals with smart metering devices and it describes routing protocols for smart grids. The following chapters summarize practical experience with addressed issues in Europe and in the Czech Republic. The last part is dedicated to evaluation of smart metering implementation in the Czech Republic.

Visualization of PLC/BPL communication in the map
Klíma, Petr ; Rusz, Martin (referee) ; Benešl, Lukáš (advisor)
The bachelor thesis deals with the implementation of an application for visualization of the PLC communication network (PowerLine Communication). The principle, advantages, disadvantages and variants of this type of communication are analyzed. Attention is also given to the use of this technology, especially in the construction of smart grids and for the diagnosis of cable lines, which is also used by the application. The thesis also deals with the problem of predicting the state of cable lines and the parameters on which this prediction is based. Some current possibilities of map visualization are also discussed and the application itself is created using the javascript library Leaflet and static map tiles. The application is focused on BPL technology, but it allows storing data on any connection made by any transmission technology. It allows displaying information about the network and displaying network elements on a map, filtering BPL connections according to the state of the cabling, configuring individual parts of the topology and the ability to create and read database backups. The behavior of the application can be easily modified by editing the file with constants.
