Utilization renewable energy sources inside of EPS Czech Republik
Zmeškal, Pavel ; Procházka, Zdeněk (referee) ; Matoušek, Antonín (advisor)
The purpose of this work was the analysis of current state and further development of renewable energy in the Czech Republic. And next their effects on the electricity system of the Czech Republic. On the basis of established facts has been developed actual state of renewable energy sources. The current situation is only orientation and is still changing at this time. Another objective was to evaluate the various renewable energy sources in terms of their impact on the electricity system and recoverability in the Czech Republic. In more detail were read up the conditions for the wind power plants operation and their connection to the electricity system of Czech Republic. In fine were discuss the impact of renewable energy sources on electricity system and prerequisite for their further development in the Czech Republic.

Comparison of Connection Conditions of Photovoltaic Systems in the Czech Republic and the Slovak Republic
Vašica, Radoslav ; Radil, Lukáš (referee) ; Paar, Martin (advisor)
The objective of this work is an analysis and a comparison of legislative conditions of the connection of the photovoltaic power station on the territory of Czech Republic (CR) and Slovak Republic (SR). Presented are the working procedures for connecting of the power station to Distribution Grid (DG) and requirements of individual documents needed for a successful connection. Listed are also circumstances, which are taken into account during the consideration of the influence for connection, for the safe operation of DG. In the work are discussed the ways of support of constructing buildings of the photovoltaic power plant and the principle of repurchasing energy from renewable sources. The other part of work deals about hybrid photovoltaic power stations (HPPS), thus allowing to the power station to save energy into accumulators. There are the composition and principle of operation of the hybrid power stations. The following part deals with options of connectivity with hybrid power station to the DG. There are explained the advantages and disadvantages of connected and unconnected hybrid power plants to the DG.

Use of thermal solar collectors for pool heating – design of application
Zatočilová, Aneta ; Košner, Jan (referee) ; Jaroš, Michal (advisor)
The objective of this bachelor’s thesis is to evaluate the possibilities of using solar collectors for swimming pool heating. The solar pool heating is often combined with solar water heating. The thesis examine technical parameters, effectivity and purchase cost of the thermal solar systems for both mentioned applications. The first part of the study is focused on general description of the solar radiation, its availability and potential of usage. The next part is dealing with collectors’ energy budget, their efficiency and means of their insulation. Further, there are described the most used types of the thermal solar collectors and various constructions of the thermal solar systems of nowadays. The last part is dedicated to specific project of thermal solar system for pool heating and its price budget.

Assessment of the impact of different types of RES in the power system
Zmeškal, Pavel ; Matoušek, Antonín (referee) ; Mastný, Petr (advisor)
This thesis deals with usage of each kind of RES under conditions of Czech republic and their usage at areas placed in. Consequently supplied RES output power at time and its influence on reliability of supply in EPS CZ. Way of operation of RES from point of view of requirement on regulation and control of operation of EPS is more studied on operation of different kinds of wind power plants, which due to its variable output power affects not only EPS CZ. At final caption, economic influence of RES to EPS is reviewed as a unit, increasingly claims on regulation, increasingly benefit on support of RES. All these influences increase price of electricity for end user.

Measuring and regulation of computer controlled solar systems: Vizualization of energetic systems
Vlčnovská Kotlíková, Silvie ; Mašek, Ivan (referee) ; Půčková, Helena (advisor)
This work is oriented on study and evaluation of performance of real operating solar system. There was made analysis of actual technological unit and there was suggested mode of measuring of nodal parameters. There was made interconnection between the head operating unit of the solar system and the web server. And there was prepared software for grafical image of time and temperature dependence and for data transfer to ready web application. It primarily talks about increase of efficiency of real technological unit through regulating of parameter that is using up of accumulated energy.

Boundary conditions for the operation of thermal energy distribution
Floreková, Skarleta ; Horák, Petr (referee) ; Hirš, Jiří (advisor)
Bachelor thesis ,,Boundary conditions for the operation of thermal energy distribution” is primarily focused on the analysis of the boundary conditions of balneotherapy operation at Slovak Health Spa Piešťany, a. s.. Due to its content, thesis is structurally divided to the analysis of internal and external boundary conditions. In the part of experimental analysis of internal boundary conditions, the incrust was taken from distribution pipelines of natural healing water and subsequently subjected to chemical analysis and to differential thermal analysis. Partial conclusion of this part lists the recommended material list and procedures, leads to elimination of incrustation form on the surface of materials from natural healing water. The second part is focused on the analysis of thermal fields in the subsoil at Slovak Health Spa Piešťany, a. s. and on usage possibilities of ground energy. For initial state, based on measured temperatures in the drills and project documentations, 2D thermal fields were created, by which it is possible to define zones with high and low potential usage of energy. Documents serve for the design way of energy use and for experimental verification of current state of thermal fields.

Production of biogas as an automotive fuel from renewable materials
Frühbauer, Zdeněk ; Houdková, Lucie (referee) ; Dlabaja, Tomáš (advisor)
The aim of this thesis is to specify and summarize possibilities of biogas production as a motor vehicle fuel by using the renewable energy sources. In the first part of the thesis there are the data concerning biogas, its production and chemical composition. An important part of the thesis is a description of current most used methods of cleaning which adjust biogas to quality of natural gas. The important part of this thesis is to introduce some of already working projects and to get knowledge about possibilities of making biogas from biologically decomposable material as a renewable energy source. The close of the thesis deals with energy, economy and ecological audit too and values biogas through all angles which decide about its using in larger size in the car industry.
