Negative impact of Smart Cities on human society
Sakharova, Daryna ; Froehling, Kenneth (referee) ; Sedláček, Pavel (advisor)
Koncept Smart Cities je považován za nový způsob lidského bydlení. Hlavním úkolem této práce je určení role klíčových komponentů Smart City, za účelem zhodnocení zda Smart technology přináší pohodlí a zahrnuje oblasti, kde se lidé cítí v bezpečí. Ve své bakalářské práci představuji koncept Smart City za pomoci analýzy a zvážením různých definicí. Pro objasnění konceptu a vysvětlení jeho užití bylo nutno zahrnout i kapitolu věnující se historii tohoto termínu a fenoménu. Aby čtenář snáze pochopil problematiku konceptu Smart Cities a jejich potenciálních negativních dopadů, bylo nutno zabývat se i faktory, které ovlivňují vědecké vnímání toho výrazu. Stanovením hlavních nevýhod jejich realizace se zabývají poslední dvě kapitoly mé práce. V nich poskytuji detailní popis stávajících problémů, uvádím příklady a objasňuji důvody pro jejich výskyt.

Cyber security tester of elements used in industrial networks and energy industry
Březina, Jiří ; Mlýnek, Petr (referee) ; Lieskovan, Tomáš (advisor)
This thesis deals with the issue of security analysis of DLMS/COSEM protocol and exploitation of these vulnerabilities in real Smart Grid environment. Thesis starts with a description of power grids in the past and present, introducing the environment of modern power grids and the smart grid elements used in it this power grids to reader. This is followed by a detailed discussion of the communication protocols that operate in these networks, beginning from the older and more industrially based Modbus protocol to the DLMS/COSEM protocol which is most used today and his various components and security. The most common current models of link vulnerability attacks are also summarized in the paper. The thesis aims to implement a tester that tests the security of smart grid elements, mainly on the vulnerabilities described in the thesis. The tester primarily focuses on the vulnerability called replay attack and evaluating the execution of this attack in a laboratory environment.

Secure and privacy-preserving data communication
Bernát, Michal ; Člupek, Vlastimil (referee) ; Malina, Lukáš (advisor)
This thesis discusses the possibility of ensuring the safety, integrity and authenticity of data communication with respect to user privacy. This thesis describes the fundamentals of smart grid networks with capabilities of existing forms of security to communications that have been chosen as a target for application deployment of group signatures to ensure the security, integrity and authenticity of data communications. It describes the concept of a zero-knowledge and cryptography primitives. Further, the basic principles are presented, the history of development, and various schemes are compared based on the construction and performance. The second part is given to the deployment and optimization of group signatures for computationally limited devices. Within the draft report were to be implemented in the Java language chosen scheme HLCCN, DP and BBS. They were then tested under various platforms which were measured and evaluated performance parameters of the schemes. The optimization of the work is focused on the times of signatures, which are critical to a smart grid system. Under the platforms are deployed pre-processed pairing optimization methods and other methods resulting from the deployment platform as JPBWrappera and native libraries to deliver more efficient times of sgnaiture. At the end of the thesis are evaluated achievements of optimization methods and the appropriateness of the deployment of smart grids.

BPL modem
Chromý, David ; Mlýnek, Petr (referee) ; Musil, Petr (advisor)
This work deals with the issue of PLC with a focus on BPL technology (Broadbandover-power lines), which is explained in the theoretical part. The work describes in detailthe main components for PCB design with manufacturing and mounting process. Fur-thermore, the thesis provides instructions on how to establish communication betweenBPL modems and a description of individual functions. In conclusion, the procedureof measuring the noise intensity in the 230 V power line is described with the results.The output of the diploma thesis is the selection of components and the implementationof printed circuit boards for two BPL modems. These modems allow to measure SNR(signal to noise ratio) at physical speed.

Providing flexibility with detachable loads Procurement and commodity product prediction
Sykora, Jan ; Radil, Lukas ; Pilař, Martin
Flexibility is generally considered as the potential ofa facility (generation/consumption or storage) to actively changethe amount of its generation/consumption/accumulated energybased on price signals or direction. This control strategies ismanaged to correct deviations of the electricity grid or to ensurethat the purchase/sale of electricity is profitable for the flexibilityprovider. This paper presents a comparison of the control of heatpump consumption to provide consumption flexibility.

Basic principles of flexibility aggregation
Ošťádal, Martin ; Paar, Martin (referee) ; Radil, Lukáš (advisor)
This thesis deals with the basic principles of flexibility aggregation. In the beginning it introduces the history and present state in the field of regulation and prospects for the future. After defining the concepts associated with flexibility and aggregation, the necessary modifications for the functioning of flexibility aggregation are formulated. Next, foreign methods of energy regulation are mentioned, as well as possible obstacles to these new methods in the respective countries. The paper concludes with an analysis of data from Pecan Street Inc. to show the effect of flexibility on daily load profile and the similarity of power waveforms throughout the day for provided households.

Using artificial intelligence for energy management in smart buildings
Michálek, Jiří ; Mikulášek, Michal (referee) ; Jablončík, Lukáš (advisor)
This master’s thesis deals with the problem of home energy and energy management in the house using artificial intelligence algorithms. Its objective is to analyse the available energy resources on a small and medium scale, including resources that are currently under research with a future perspective. Additionally, its objective is to explore the field of artificial intelligence and its application in the energy sector, to develop a design for a home photovoltaic power plant and to design a control algorithm with artificial intelligence elements. As a result of the thesis, the research analyses energy resources, fundamental types of artificial intelligence and specific applications of artificial intelligence in the energy sector. The work includes the design of the electrical installation of a home photovoltaic power plant. In the thesis was developed an overview of the requirements for energy management algorithms for buildings. Based on this overview, a control algorithm was designed. Within the design of the algorithm was applied neural networks as artificial intelligence elements.
