Possibility of using alternative decentralized energy sources
Pitron, Jiří ; Pěcha, Jiří (referee) ; Mastný, Petr (advisor)
The thesis concerns of the possibility by using alternative decentralized sources of energy. The first chapter describes current energy situation in the Czech Republic and consideration of future electrical energy consumption and the coverage by the renewable sources. Another part of this chapter describes each types of renewable energy with their advantages and disadvantages related to the Czech Republic. In the second chapter are introduced inputs which are appropriate for the plan of energetic system. The following theoretical chapter deals with each types of alternative energy sources using renewable source including the possibility of the installation and plan for the building. These alternative sources are sorted out by the way of using renewable sources of energy. The theoretical-practical fourth chapter concerns of the heating by the heat pump. For the detailed description was chosen the heat pump which is currently denote as appropriate alternative source of heat in household. With appropriate plan, which the thesis deals with, is this alternative source considered as proper investment. In the last chapter was assembled programme for creating models of energetic flux and calculation for the plan of heating by the heating pump air/water. This model is taken for concrete buildings related to exact outdoor temperature from previous years in concrete locality. In the end was realized validation of the software with the real measurement in concrete building.

The Economic Effectiveness of Wind Power Project
Vániš, Jiří ; Radil, Lukáš (referee) ; Macháček, Jan (advisor)
The following text is devoted to wind power stations. It shows basic distribution of wind engine according to the principle of their function and suitability of their use for power generation. It shows the parameters that must satisfy the suitable sites for building wind power stations and it shows wind maps of the Czech Republic. There are described some of the most frequently installed machines in the Czech Republic. Next chapters describe the economics running part of wind power stations; analyze the basic cost-sharing, mention methods of tax depreciation of tangible assets, the redemption value of electrical energy from renewable sources. There are chosen some of the most used methods for assessment the economic efficiency of wind power stations. There are common methods of static and dynamic in terms of time value of money, the possibilities and limitations of their use. This information is a basis for designing and implementing a program to calculate the economic efficiency of wind power station. The goal is to create a computer program based on your input values and calculation methods to calculate the economic indicators and economic effectiveness of project wind power station in terms of total investment coasts and on equity capital projects. Based on evaluation of data it will be ready to determine whether the investment in to the construction of wind power station can provide the required funding.

Accumulation of Energy from Renewable Energy Sources
Heller, Ondřej ; Radil, Lukáš (referee) ; Mastný, Petr (advisor)
The objective of the first part of master’s thesis is mapping the potential of various types of renewable sources in Europe and Czech Republic, especially solar energy, wind energy, water energy and biomass. There are described principals and ways of energy generation from these sources, brief overview of current technologies, and also their advantages and limitations. An important part is electric supply continuity from renewable sources, there are large differences and the resulting to restrictions on construction and connecting the units to the power system. In this work there are mentioned some impacts on network and rates of change of supply, some sources are also evaluated in terms of maximum power, that can be connected to the power system in our country. The conclusion of the first part is dedicated to energy storage technologies, which are suitable and usable for renewable sources, there are described their principals, properties, status of development and types of aplications, in which these technologies are used. This chapter also focusses on the price level of each technology. The second part of the thesis deals with 1 MWp on-grid photovoltaic power plant design. This design includes also the redox flow batteries accumulation, the first variant calculates on 24-hour steady energy supply, the second optimalized variant calculates on daily energy supply. There are the accumulation system costs estimated and also the payback period for the both variants. Additionally there is also determined minimum penalization for cost-effective operation. The last part is dedicated to changes of impact on the local grid and changes of system impacts, after the accumulation system is installed.

Predictability of wind famrs operated by Amper-Market company
Farda, Aleš ; Rajdl, Kamil ; Štěpánek, Petr
This report contains an analysis of the electric energy production of wind power plants of the company Amper Market a.s. from the point of view of its predictability, with the main objective of determining the potential accuracy of hourly predictions of the power production. To calculate the analyzed predictions a regression forecasting model utilizing wind speed and direction in two height levels is used. The necessary values of these meteorological variables are obtained from three numerical weather prediction models – Aladin, EPS Aladin and IFS. The accuracy of the energy production predictions is optimized regarding the choice of suitable geographical points for obtaining outputs of the numerical models, the combine utilization of the models and individual setting of the regression model for the single power plants. The analysis was performed based on data from the period January 2013 to April 2014.
