Consequences of blackouts on agricultural farms of South Bohemia
PARLÁSKOVÁ, Lucie
Electrical energy plays an indispensable role in our contemporary society. However, we mostly realize its position in agriculture in a situation which often already entails irreversible consequences. Therefore, the thesis aims to assess the consequences of power blackout on agricultural farming. In connection with the selected objective, a question arises whether long-term power blackouts also constitute a serious threat to agricultural farms of South Bohemia? The theoretical part briefly describes electrical energy, its production and method of transmission. It also includes basic elements of the power system including its stability and safety. The chapter also acquaints the reader with the critical infrastructure of the Czech Republic and its legislative base. Then, it globally analyzes the term blackout.Given the topic of the thesis, it is necessary to mention the valuable work of the integrated rescue system which in addition to the basic obligations to ensure the protection of human life and property is required to provide missions to rescue animals in emergency situations. Finally, this chapter deals with the application of electrical energy in agriculture, including the characteristics of surveyed farms and a high degree of automation used in farming.The research part is based on the search of the current state of selected agricultural farms. The research was focused on the South Bohemian Region which makes no exception in relation to this issue. Used for the research was a qualitative method of data collection with the information obtained through the techniques of controlled interviews and the secondary analysis of data provided by competent employees of farms in South Bohemia. The results are then outlined in two planes. During recent years, breeding stations have been completely renovated, especially in the section of technological processes. Modern electronic devices which include e.g. automated milking, feeding, suction and washing equipment, heating of service water and heating, should ensure trouble-free operation in such farms. However, what the vast majority of farms is not adequately prepared for is to ensure their smooth operation even during a failure of the electrical system. A number of farms do not have an alternate source of electrical energy. The percentage of self-sufficient farms having on its premises a pumping station that can supply the local diesel-aggregate, is also negligible. Moreover, in case of a diesel-aggregate failure, no alternative source is available. A crucial problem arises in the category of poultry. The animals are situated in large-volume halls where all processes are controlled by fully automated control systems. An alternative source of electrical energy is a crucial element needed to ensure normal operation of the farms. Unless the established criteria are in compliance (ventilation, lighting, etc.), reaction of the animals becomes evident within tens of minutes. Any deviation results in rapid loss of animals. It is assumed that the resulting data will be used both for research purposes in the area of secondary impacts in case of electrical system failures and for objective assessment of the effectiveness in farming security within the current methods. The purpose is to educate the above entities.

Optimal parameters of risk management for electricity trader
Jančová, Lenka ; Paholok, Igor (advisor) ; Kovačovská, Lenka (referee)
The priority of this work is to show the importance of risk management and the proper operation in electricity trading companies. In the theoretical part of the thesis are summarized basic information about the energy market in the Czech Republic and also a brief overview of the risks observed in the electricity trading. In recent years there have been several cases where a company did not observe their risks or even did not monitor these risks at all. This had a negative impact on the entire Czech energy market. In the practical part of this thesis are described the cases of companies Moravia Energo a.s. and Korlea Invest a.s., setting its risk management and also consequences of their falls. Furthermore, this work describes the different tools to support risk management, which are not the cheapest definitely. Also work contains an example of calculating the limits for credit exposure of the two companies that I calculated based on the analysis of the annual reports of these companies and I managed to get a lot of interesting information during writing this work that the reader will definitely appreciate.

The impact of blackout on South Bohemia region
SMEJKAL, Pavel
The thesis is concerned in problem that can occure after a blackout. The South Bohemia region was chosen as the area of blackout impacts. The theoretical part of the work describes a critical infrastructure, whose part electrical energy is. It also learns about the electricity supply system in the Czech Republic and explains what is considered to be a blackout. The research is made in two levels. First there are processed baground researches of selected blackouts in the world and consequently the impacts of possible blackout in the South Bohemia are examined. The method of guided interview was used to make a questionnaire. The guided interviews were made with a few specialists. The questionnaire results are analysed and the possible consequences of blackout in the South Bohemia region are described. The main purpose of the work was ? The description of a blackout in the South Bohemia region?. The aim was fulfilled and a blackout in the South Bohemia region was described. The thesis worked with two hypothesis. The first one was ?A blackout strongly influences the population? a this hypothesis was proved by my research. The second hypothesis sounded ?Electrical energy is a strategical part of a critical infrastructure in the South Bohemia region?, and this hypothesis was also proved on basis of my results.

Regulation and trading on the electricity market in the Czech Republic and in selected EU Member State
KLÁNOVÁ, Martina
Electricity is a strategic and therefore highly valued commodity worldwide. Its importance and price is constantly increasing over time. It is gained from various sources and its major drawback currently is its limited storability. For the above reasons, the production, distribution and sale of electric energy take place on the energy market governed by separate laws and regulations, as well as directives of the European Union. In order to protect the competition and prevent companies from abusing of dominant position the electricity market must be regulated.

Carbon footprint of computers in the computer class at VSE
Kovařík, Lukáš ; Gála, Libor (advisor) ; Basl, Josef (referee)
This bachelor's thesis is about carbon footprint. It looks into assessing of carbon footprint. Theoretical knowledge is applied afterwards in a case study. Main goal is assessing of carbon footprint of computers that are located in computer class. The first part is about definition of carbon footprint. Then there are presented three different points of view of carbon footprinting. There is a part focused on software solutions that helps companies monitor their carbon footprint as well. Second part of this thesis includes the case study that is focused on assessing of carbon footprint in the area of information and communications technology. There is an analysis of activities and processes that computers in class are involved into. Then the consumption of electric energy is measured. On its basis the size of carbon footprint is calculated. The result offers the estimation of University of Economics' size of carbon footprint that is suitable indicator in the context of environment protection.

Completion of Nuclear Power Plant Temelín and its possible impact on Czech Republic's position in electricity trade
Fučík, Václav ; Němcová, Ingeborg (advisor) ; Horák, Jiří (referee)
This work tries to answer the question, if completion of the Nuclear Power Plant Temelín is necessary and advantegous. The completion is important for electricity market stability in the region of Central Europe. In Czech Republic's neighbouring states prevails the tendency of reducing their production capacities (for example German nuclear phase-out or closing of Polish coal power plants), the demand for Czech electricity will be probably ensured. Many of European states exploit nuclear energy, therefore it is not likely to ban it. Nuclear energy does not burden the environment and its exploitation is in comparison with other energy sources economically more favorable. Energy production using renewable sources is not stable and reliable enough, therefore it is impossible to build the whole electricity production sector on them. It is necessary to keep in mind the possible depletion of fossil fuels, which are for electricity production crucial at this time. On the other hand, there is a sufficient amount of nuclear fuels.
