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.

Influence of RES to power system in Czech Republic
Vánišová, Michaela ; Bartošík, Tomáš (referee) ; Mastný, Petr (advisor)
This text deals with renewable energy sources in terms of working on the electricity network of the Czech Republic. There is the definition of renewable energy sources in the work. Next there are discussed the basic information about connecting to the distribution network. In two parts, there is mentioned and discussed the issue of operation of renewable energy resources and their effects in terms of the electricity network. The last chapter is focused on the possibility of further utilization of renewable energy sources because of their natural energy.

Cogeneration influence on power industry and power market in Czech Republic
Dudáš, Michal ; Cerman, Marek (referee) ; Macháček, Jan (advisor)
The main goal of this master’s thesis is to find out the impact of future development in combined heat and power technologies, especially the impact on power market in Czech Republic regarding to historical development of photovoltaics and subsidy policy. There are three scenarios of installed power growth designed including calculations of renewable energy source financial fee as well as overall evaluation. The paper also deals with current status of combined heat and power technologies in Czech Republic, European Union and USA as well as legislature framework of CHP in Czech Republic and EU. There are also kinds of state grants described. In economical part of the paper there are NPV’s of particular cogeneration units calculated. The calculations were made both with current investment costs and reduced investment costs.

Cogeneration plants on vegetable oil
Macoszek, Pavel ; Baxant, Petr (referee) ; Radil, Lukáš (advisor)
The thesis is focused on cogeneration units on vegetable oil. The first chapter contains basic information about the production, supply and consumption of electric energy in the Czech Republic and about renewable energy sources. The following chapter is devoted to possibilities of use oil kinds of phytomass in the Czech Republic, or products made from them. Next chapter is mentioned on legislation allowing the use of used cooking oils for energy purposes. It contains a summary of the laws and regulations and options regarding subsidies for electric and heat power. The main objective of these chapters is to explain the issue of the establishment and operation of cogeneration units on vegetable oil. The following chapters are devoted to the design and study of simultaneously operated cogeneration unit on the vegetable oil with a combustion engine and the calculation of economic operation running. The reason of study is to evaluation, which on based of the input values and calculation methods determine the economic efficiency of the project cogeneration unit on vegetable oil under mode purchase price and mode green bonus. Appreciation is also given to the overall legal review and responsibilities of cogeneration units on vegetable oil.

Characteristic of photovoltaic system
Pokorný, Marek ; Dolenský, Jan (referee) ; Vaněk, Jiří (advisor)
The aim of this work is informed first about photovoltaics universally, works to inform the photovoltaic panels and complete plants. The work also includes instructions on how to implement PVP in accordance with law. Another part is the rough draft of the photovoltaic power 30 kWp, which can be placed on the house, computation and calculation of investment and them profitable investments to time. Design is made in two separate forms of the Fronius Solar and Sunny Design, their outputs are compared. The practical part of this work cooperates with the company SOLARTEC Ltd. for experimental measurements of the photovoltaic system and develop a methodology for setting the properties of real solar systems in operation from the measured data then stored in a database. These data further evaluate and compare the similar operating conditions. This data will show as the course of production of electricity during the typical day in percentage terms, depending on the incident irradiance, cell temperature, angle of incident radiation, etc. We can compare what it looks like an ideal day in terms of production of photovoltaic power, with the other days. Further are in work mentioned histograms achievement panel behind classical day and behind all - time investigation.

The development of consumtion of rewewable energy sources in the Czech republic after 2000
Mrůzková, Veronika ; Dvořák, Antonín (advisor) ; Hadrabová, Alena (referee)
This bachelor thesis focuses on the consumption of renewable energy sources in the Czech republic thesis is divided into three parts, first chapter is theoretical and the second and the third are practical. The theoretical part deals with these terms: renewable energy sources, working of each of chosen sources and the suitability of chosen source in the Czech republic. Second chapter covers specific terms such as extension of each chosen source in the Czech republic, granted subsidies for renewable energy sources and total costs of these subsidies. The reason of extention of renewable energy sources can be found in this chapter. Last chapter descibes technical and economical characteristics of chosen biogas plant. It also evaluates the investment by using different methods such as cash flow, NPV, IRR or payback period. This chapter contains sensitivity analysis too. This analysis shows how sensitive are the costs of biogas plant.
