Accumulation of electricity from renewable sources
Plíšek, Petr ; Špiláček, Michal (referee) ; Pospíšil, Jiří (advisor)
This diploma thesis deals with the issue of accumulation of electricity produced by renewable sources. The first part focuses on the description of possible ways of accumulation, especially with focus on those methods, that are suitable for renewable energy sources. The next part deals with the design of the accumulation energy in the compressed air for the selected photovoltaic power plant. The necessity of designing a particular method of energy storage, is also its technical and economic analysis, which is the content of the last part of the thesis.

Project for an automouse source of electrical energy
Vinkler, Stanislav ; Bok, Jaromír (referee) ; Matoušek, Antonín (advisor)
Purpose of the thesis is enlarged the theory about potential utilization of an autonomous (autonomic) electric power supply used for a family house. Forepart will dealt with description of the resources in accordance with conversion of different kinds of energy to electric power. There will be always given the principle of the power generation as well as a list of main components of the system for each single source. Second part will be focused on generator output assessment of the autonomous source to ensure the power supply for the model family house. There will be my own design of the autonomous sources namely a project of a small hydropower plants and a project of a cogeneration unit in the third section of the thesis. The last part is aimed at the techno-economical evaluation of the engineered sources.

Engineering solution of photovoltaic power station
Gajdošík, Ivo ; Sobotka, Jiří (referee) ; Míča, Ivan (advisor)
This thesis deals with the usage of solar photovoltaic panel production of electic energy. First part focuses on solar radiation alighting the Earth, respectively the area of Czech republic. Next part covers a development of photovoltaic from the very beggining til nowadays, it describes its spread in the world and the area of Czech republic. Then a reader us introduced to physical principles that work inside solar cells a one single chapter desribes individual parts of photovoltaic power station. Next chapter is dedicated to a model study of photovoltaic power station devided in two alternates- with stacionary placement of panel and placement on trackers, where after a market research, there is a whole technical solution designed and economical and delivery balance is calculated. At the last part there are described main directions of development in the field of usage of solar energy for electric current production.

Management of the energy transmission system polygon
Bohačík, Antonín ; Musil, Petr (referee) ; Blažek, Petr (advisor)
The diploma thesis is focused on the creation of a control interface for a polygon simulating the electrical distribution network of the Czech Republic, where communication between substations is realized by IEC 60870-5-104 protocol. The theoretical part of the thesis explains the basic principles, properties and possibilities of communication standards IEC 60870 and IEC 61850. The next part is focused on the actual implementation and subsequent implementation of the control interface, including the implementation of the IEC 61850-80-1 module for data transfer between the mentioned standards. The last part describes the created behavior scenarios or the analysis of communication itself.

Project of optimalization and cooperation of power units
Hübková, Ivana ; Mastný, Petr (referee) ; Radil, Lukáš (advisor)
This bachelor´s thesis deals with heat circulation in condensing thermal power plants and the possibilities of increasing their effectiveness. Specifically it addresses several topics, namely: "increasing of inlet steam parameters, improving of vacuum in the condenser, regenerative heating, reheating of steam and, last but not least, the supercritical steam parameters." Furthermore, it also deals with losses in heat circulation, power balance and specific consumption. Another part of this thesis deals with optimization of operations and cooperation of two power plant units. A case study shows the optimal power division at load. The cost and consumption characteristics of these blocks are plotted. An insight into the future of Czech energetics is made, theorizing about the advantages of dividing electrical energy distribution, from the point of view of economy, environment, and primarily, technology.

Technologies for electricity storage
Pochylý, Jiří ; Kracík, Petr (referee) ; Škorpík, Jiří (advisor)
The point of this work is to compare and to describe basic types and principles of electric storage systems. With the increasing imbalance between consumption and generation of electric energy there is a need for integration of electric accumulators to the electric grid. Technologies for electric energy storage can be divided into several types, which differ in form and conversion of energy. These technologies are suitable for specific industrial applications.
