This thesis examines with subsidies and taxes related to renewable energy generation, solar energy generation in particular. I have chosen this topic for its relevance to current situation and ongoing attention it enjoys from the media. The work comprises of five sections. In the first section, I focus on original renewable energy legislation that was in effect till year 2012. Here I discuss both Czech and European legislation with emphasis on the Czech system of subsidies based on the the Act No. 180/2005 Col. In the second part, I deal with solar generation boom during 2009 a 2010. I describe both causes of the solar boom and legislation adopted to lessen its negative effects. Specifically, I discuss the levy on solar generation, which has caused widespread debate and protests from the owners of the solar generation installations. Moreover, I discuss the reversals of the income tax examptions related to renewable electricity generation. The third part deals with finding of the Constitutional Court of the Czech Republic that reflects constitutional complaint of certain group of senators. This complaint postulated that aforementioned levy and reversal of the income tax exemption are unconstitutional, for they, according to those submitting the complaint, had retroactive effect and thus violated...

The aim of this work is to characterize the main determinants influencing the development of electricity prices. Beginnings are dedicated to the description of regulated elements of electricity bill and their development over the last period. The second part deals with power electricity and its development in the spot and futures market. The paper describes the emergence of energy prices on the market and the main determinants affecting the supply and demand curves, such as the price of emission allowances, increasing production from renewable energy and the price of energy raw materials. Part of the work is also analysis of the impact of market coupling on the market price of electricity daily market. The conclusion is devoted to seasonal fluctuations in electricity prices representing the time series.

The goal of this diploma thesis is to analyze process of migration data within the scope of SAP systems. Based on this analysis suitably desing and implement migration framework that will be used for migration of data between SAP systems. Entire migration framework and migration proces is built on technological platform SAP NetWeaver and is implemented in programming language ABAP. Functionality of the framework is presented by the case study that is represented by proper data set.

The Diploma Thesis deals with individual principles and instruments of environmental protection in the context of energy. The work is systematically divided into three parts in order to first introduce readers to the energy field with regard to the environment, and then practically demonstrate the reason behind emphasizing application of given tools and principles. In the thesis, there is an analysis of the legislative regulation of energy on all three levels, meaning international, union and national. In conclusion, potential shortcomings are pointed out, as well as controversial topics of Energy Law including recommendations for their solution.

The presented work examines the special characteristics of electricity produced by the wind as a renewable resource into which considerable hopes are being placed. Production of electricity from wind, as well as from other renewable sources, is a subject of many legislatively enshrined preferential rules. These subsidies and regulatory provisions help the energy producers but represent additional costs to every final customer and tax payer. The aim of this work is to analyse the key arguments of wind energy advocates, which are 1) economic advantage of this production due to zero costs for 'fuel' and 2) negligible burden on the environment due to zero carbon dioxide emissions. The work takes into account all aspects of wind energy production, including their financial and extra-financial implications, and shows their indefensibility in economic terms and in terms of environmental protection. Besides, I have attempted to identify institutional aspects and forms of government which is known to give interest groups a chance to succeed in their rent-seeking activities and as a result allow prosperity of the above-mentioned ineffective energy production. Attention is also paid to the observation that, given the specific technological features of electricity production from the wind, it is not possible to fully apply the conclusions of a traditional theory of economic regulation onto the current position of key players in the electricity market.

The work deals with the measurement and management in power. Provides an introduction to the problems of remote meter reading, management, and describes the current situation in the field of modern technologies Smart metering and Smart grids. It also analyzed the issue of collection of networks and data collection from a large number of meters over a wide area. For the purpose of data transmission are described GPRS, PLC, DSL, ... Further, there are given options to streamline communication. This area is used hierarchical aggregation. Using k-means algorithm is a program designed to calculate the number of concentrators and their location in the group of meters. The finished program is written in Java. It has a graphical interface and shows how the calculation is conducted. To verify the results of the optimization program is given simulation model in OPNET Modeler tool. Audited results are described in the conclusion and can deduce that using the optimization program is to streamline communications.

This work deals mainly with electrical energy. In the first part is focused on alternative energy sources, and describes structure of consumption and production of electricity over the past few years, during which is focuses on renewable energy sources. In this context, assesses the conditions for alternative energy sources in the Czech Republic from the perspective of the legislative, as well as current status and potential of alternative energy sources and tries to predict the development of these issues. The next section describes the Smart Grids as a means to achieve these goals. There are presented the basic features of this system, its goals and challenges, a description of the integration of Smart Grids with other sources of electricity and the benefits of using Smart Grids both from the perspective of user and from the perspective of system. Other parts are focused on distributed control systems in the energy sector, its development and principle. The last part is devoted to consideration of the role of alternative energy sources and distributed generation in Smart Grids.
