Super Grids Conception
Chodura, Przemysław ; Prokop, Václav (referee) ; Paar, Martin (advisor)
Cílem bakalářské práce “Super Grids Conception” je poskytnout komplexní náhled na problematiku Super Gridů ve smyslu pozadí, konceptu jako takového, dostupných technologií, dosavadních zkušeností a budoucího vývoje, možných zdrojů elektrické energie a konkrétních konceptů a studií. V úvodu jsou osvětleny důvody vedoucí k potřebě elektrických sítí nové generace – celosvětové snahy snižovat dopad výroby elektrické energie na životní prostředí, rostoucí poptávka po elektrické energii a potřeba integrovat obnovitelné zdroje energie. Možné zdroje elektrické energie jsou diskutovány jak v širším kontextu, tak i ve smyslu současných omezení a budoucího vývoje. V druhé části jsou popsány koncepty Smart Gridu, Super Gridu a SuperSmart Gridu s důrazem na přínosy, základní principy a systémové hledisko. Autor se dále zabývá jen koncepcí Super Gridu. Použití stejnosměrných (HVDC) a střídavých (HVAC) technologií je porovnáno z technického i ekonomického hlediska a z něj vycházející typické použití těchto technologií. Dále je podrobně popsána nejlepší dostupná technologie HVDC systémů – základní principy a konfigurace, popis jednotlivých částí, omezení současných technologií, dosavadní zkušenosti a možný prostor pro další vývoj. Následuje zmínka nových výzev oblasti HVAC technologií ve vztahu k Super Gridům a popis problémů souvisejících s hybridními AC/DC linkami a koridory. V poslední části jsou vysvětleny rozdíly v historickém vývoji a současných postojích v různých částech světa. Zároveň jsou představeny koncepce zvažovaných Super Gridů. Zvláštní prostor je poskytnut vizionářské koncepci vytvořené DESERTEC Foundation a technickoekonomické studii OffshoreGrid.

Data network for smart grid energy
Durkoš, Michal ; Šimek, Milan (referee) ; Mišurec, Jiří (advisor)
Electric grid as we now it has been without significant change for a long time. Along with the human population grows demand for electricity, which leads to need to create more energy. Bigger interest is in ecology and use of renewable sources, although these do not have constant output which often stresses the grid. These problems are to be solved by smart grids. Smart grids are capable of adjusting energy generation to immediate demand including renewable sources to compensate energy fluctuations in grid. They provide demand response and other applications interesting for end users. Smart grids are combination of achievements in energy, informatics and communication technology. Communication, which is key part of smart grids, has to met certain requirements and can be executed by various technologies. There are described various communication technologies and a design concept of data communication in this paper.

Data Concentrator for Smart Grids
Franek, Lešek ; Beneš, Bedřich (referee) ; Kučera, Pavel (advisor)
The goal is to design data concentrator for Smart Grids. Data Concentrator provides the interface between the server systems of distribution companies and end devices, which are electricity meters, water meters, gas meters and other equipment. There are hardware and software design solutions and there is also discussed creating its own distribution of Linux.

Alternative Energy Sources and Their Integration into the Concept of Smart Grids
Kopička, Marek ; Procházka, Jiří (referee) ; Baxant, Petr (advisor)
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.

Impact of Renewable Energy Source Introduction on Energy System in the Czech Republic
Siuda, Jan ; Bič, Josef (advisor) ; Šolc, Pavel (referee)
This thesis analyse the impact of the renewable energy resources on the transmission and distribution networks in the Czech republic. The volatility changes based on the growth of the number of production places of this kind and other negative effects are being examined. The analysis has proved difficulties in transmission networks balance management and then problems with voltage quality supply by distribution companies. The international cooperation between transmission operators is also being analysed. This thesis proves that renewable resources and their implementation have significant economic impact not only within the meaning of higher production costs.

Economic Impacts of Smart Grids
Haburová, Petra ; Hnilica, Jiří (advisor)
The goal of this thesis is to assess the impact of the smart grids implementation on PRE Distribuce, a third largest electricity distributor in the Czech Republic. The first part of the thesis presents an overview of the current energy value chain, including the division of tasks and responsibilities. Following this is the definition of the smart grid, its drivers, benefits and key barriers of its implementation. The analytical part provides a scenario analysis of the smart grid roll-out, where the first scenario assumed implementation of all technologies and components within five years and the second scenario assumes implementation in line with the depreciation of traditional components. Furthermore, the cash flow impact and NPV of the project under both scenarios is provided.

Renewable energy sources in EU energy: Selected issues
Tomčová, Ivana ; Němcová, Ingeborg (advisor) ; Vondrušková, Barbora (referee)
The goal of this bachelor thesis is to describe the principle and to evaluate the prospects of the new concept of electrical transmission and distribution networks Smart grids. This work deals with development and the three pillars of EU energy policy, the electricity market, problems in meeting targets in this area and the main challenges facing the EU. Smart Grid should be the solution to many current problems of the electricity market. In this work I try to explain how the whole system works, what technologies should be used and what benefits, respectively disadvantages would Smart Grid bring to producers, distributors and consumers of electricity energy.

The strategy of AMM system implementation within the Czech distribution system
Vycpálek, Martin ; Chlapek, Dušan (advisor) ; Weiss, Gustav (referee)
This thesis deals with issues around the implementation of an AMM (Automated Meter Management) system within the Czech electricity distribution system. The theoretical section of the thesis provides a historical context and looks at the development of the electricity sector. The thesis then goes on to discuss issues regarding the competitiveness of distribution companies in terms of IT/ICT use. This section defines the elements of the Smart Grid concept, in particular the AMM system. The chapters dealing with the conditions for implementing the system in the Czech Republic and pilot projects abroad make up the major sources for the practical section. The goal of the practical section is to come up with a project aim for the AMM system implementation trial project in Prague. The proposed project aim is divided into a number of separate tasks whose results are obtained using a detailed analysis of available sources and the conclusions of the theoretical part of the thesis. The thesis's main benefit is in forming a basis for the AMM implementation trial project in PREdistribuce, Inc. distribution networks and providing a comprehensive overview of the development and current state of the electricity sector.
