Analysis of Water Consumption
Pokorná, Denisa ; Ručka, Jan (referee) ; Tuhovčák, Ladislav (advisor)
The subject of the bachelor thesis is the processing of water consumption analysis in the area of building faculty. The bulk of the work is devoted to the evaluation of the data obtained by the smart metering system, which is currently only installed on the billing water meter number 2 located on Veveří Street. The Faculty of Civil Engineering is very interested in new trends and possibilities to more effectively measure water consumption. The conclusion of the thesis deals with the appropriate design of the alarm values of consumption and the possible counting of other water meters in the area and associated faster and more transparent information about the water consumption values. An integral part of the work and water consumption are general information on the need for water for which there are no up-to-date comprehensive methodologies to accurately determine it. Analyzing already measured data seems to be the most accurate way of determining it. Part of the thesis is also a chapter focused on the development of water consumption in our country as well as in comparison with abroad. At present, there is a decreasing trend in water needs that began in the 1990s.

Analyses of the breaker/limiter functions for low voltage supply points
Bajánková, Denisa ; Toman, Petr (referee) ; Topolánek, David (advisor)
The diploma thesis provides an insight into the remote control and disconnection of DSO supply points phenomenon. The remote or local disconnection/connection of supply point is allowed by the breaker function. The automatic disconnection of supply point is enabled by the limiter function. Due to the anticipated implementation of smart meters in the Czech Republic in the future, this work contains the comprehensive description of breaker/limiter function with proposed possibilities of use in the Czech Republic. The thesis deals with the current breaker/limiter function use in the Czech Republic and in other countries. It introduces the smart meter installation in pilot projects to analyze the breaker/limiter function use in other countries. The thesis is focused on the technical solution of breaker/limiter. Moreover, it describes the ways of connecting the breaker, settting the limiter, connecting/disconnecting a supply point and breaker operation. Further, the thesis introduces the ways of activating the breaker by a customer and defines in which cases it is possible to limit and interrupt the electricity supply in the Czech Republic currently. The main aim of thesis is to describe the specific possibilities of breaker/limiter function use in the Czech Republic. With regard to the function use in other countries and the limiting or interrupting the electricity supply by DSO according to energy law, the possibilities of use are proposed. Each possibility of use is analyzed when implementing the breaker function or the breaker/limiter function. The benefits are defined for a DSO and for a customer. The proposed uses are evaluated in terms of applicability and valid legislation in the Czech Republic. The result of this work is the summary of information about breaker/limiter function which is one of the new features in the implementation of smart metering. The function installation and the implementation of possibilities described in the thesis depends on the DSO decision.

Vliv nových technologií v energetice na domácnosti
Novák, Dominik ; Strouhal, Jiří (advisor) ; Žádník, Josef (referee)
This masters thesis aims to assess and evaluate the potential of home based energy storage systems for the final user. In theoretical part it therefore describes the historical development of the European power sector with the purpose of determining, what was the impact of this development on products offered by energy providers to the final consumers of electricity. Findings from this analysis are then used to design a model, which is introduced and described in the practical part of the masters thesis. This model is afterwards used to assess the profitability of home batteries implementation by three different types of households and also to determine, what are the key drivers and constraints for the adoption of energy storage systems by households.

Introduction of Smart Metering: Ramifications for Business Management in Medium-sized Energy Providers
Selmke, Pierre ; Heřman, Jan (advisor) ; Neumaierová, Inka (referee) ; Markovič, Peter (referee)
In the European Union (EU), increasing final energy efficiency, so as to save energy, has become mandatory. This obligation will fundamentally alter the EU energy sector. The relevant EU directive, 2006/32/EG, requires that adjustments be made to energy billing and, where technically feasible, that new metering technologies (i.e. smart metering) be introduced. Individual EU countries are implementing these requirements in different ways: Smart metering is either being nearly fully implemented (e.g. in Italy), is being planned (e.g. in Germany), or completely disregarded (e.g. in the Czech Republic). Since the introduction of smart metering affects virtually all value-added steps, organisational structures and areas of operation in medium-sized energy providers, these providers must take the relevant requirements into account at as early a stage as possible. The present thesis analyses the effects of the introduction of smart metering on the business management of such companies. A deductive method was chosen and the effects of intro- ducing smart metering were assessed through a cross-sectional study of two separate data collections. Experts were interviewed and their statements were qualitatively evaluated. A written survey followed via online questionnaires, the results of which were quantitatively evaluated. Institutional, functional and activity-based perspectives were considered as well as normative, strategic and operative aspects of business management. The evaluation of the survey enabled a better assessment and analysis of the introduction of smart metering. An analysis of the scope of the upcoming alterations within energy providers illustrates just how fundamental a change this will bring to medium-sized energy providers. However, the outcome of the written survey shows that most executives do not recognise this need for change and therefore are unable to initiate it. These management deficiencies threaten the very existence of these companies and must be resolved through the timely initiation of consistent change management.
