Barriers of renewable sources expansion in the Czech Republic
Lukášek, Kamil ; Březina, Ladislav (referee) ; Mastný, Petr (advisor)
Currently, there is no publication that concerns the renewable resources comprehensively in the Czech Republic. This publication defines the renewable resources in general meaning. Whereas the physical and legal definitions of the renewable resources are different, text explains the principle of production of electricity according to the legal definition. When the renewable resources are being constructed, it's important to achieve the optimal operating conditions. To achieve these conditions, it's necessary to locate the renewable resource in the Czech Republic. The operations of renewable resources are partly financed by the country, in order to be more interesting for the investors. Further on, the conditions of connection to electrical distribution system are defined. The impact of renewable resources on electrical distribution system. Finally the conception of renewable electrical energy resource for region of East Bohemia is designed.
State of photovoltaic in the Czech Republic
Lukášek, Kamil ; Bača, Petr (referee) ; Vaněk, Jiří (advisor)
Photovoltaic in the Czech Republic has gone through significant development during last few years. The thesis describes physical principle of converting solar energy into electrical energy using photovoltaic cells. Photovoltaic power plant is a set of technologic components connected together to utilize solar energy and convert it into electric energy that could be distributed to electric power network. Review of the photovoltaic development in the Czech Republic and the list of the biggest operational photovoltaic power plants present important data for assessment of the current status of photovoltaic technology in the Czech Republic. Chapter operations and maintenance of photovoltaic power plants summarizes the most common causes of failures and presents diagnostic tools for service requests. Due to legislative changes, hybrid photovoltaic power plants construction has been prioritized as it is economically more efficient now. Construction of new hybrid photovoltaic power plant was assessed analytically using SWOT analysis that evaluates strong and weak sides of the projects in comparison with opportunities and threats of construction. After evaluation of obtained data the next steps of the hybrid photovoltaic power plant’s construction plan are proposed. The first part of hybrid photovoltaic power plant design contains PVGIS program's data evaluation, which provides sunlight intensity information for specified area. Obtained data were used in the second part of the design to determine proper components selection for family house hybrid photovoltaic power plant. Finally the economic view of the design and return of investments were assessed.
