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.

Configuration and diagnostics for Smart Grid
Hrbek, Martin ; Šťastný, Ladislav (referee) ; Franek, Lešek (advisor)
This thesis designs a solution for configuration and diagnostics for the Smart Grid. It creates use case diagram for configuration and diagnostics and designs individual software modules of the system. The thesis informs a developer about suitable devices for configuration and diagnostics for the Smart Grid, especially about rugged handhelds. The thesis chooses suitable software tools for development of designed modules and contains recommendations for developers, how to use this tools. The realization of one of the designed modules verifies the correctness of the designed solutions and approaches.

The Benefits and Pitfalls of Smart Meter Data Collection
Bazal, Stanislav ; Morávek, Jan (referee) ; Šedrlová, Magdalena (advisor)
In recent years, the demand for electricity has been increasing in households because various appliances and newest technologies have been used on an everyday basis. This raises concerns about the lack of electricity production around the globe. There is also a need for people to track their daily power usage in houses. The aim of this thesis is to explain the term smart metering and its benefits for both people that might use this technology in their households, and for companies. Smart meters allow people to track and control their energy consumption and eventually it might result in cheaper costs of the resources. What is more, the smart meters help consumers to know specific information about the consumption of electricity for appliances. In a global scale, the smart metering technology is used in smart grids which are more environmentally friendly power grids with higher efficiency and greater energy production. This work also focuses on the overall distribution of smart meters both in the Czech Republic and in the world. Nowadays, there are many projects in progress that are trying to switch from traditional power plants to smart grids with the intention to increase energy production and to become eco-friendly. The companies behind these projects have already published some of their researches which bring positive information about the energy production. The majority of these projects should be in progress until 2020 and some until 2025. Therefore, the final conclusion whether the smart metering technology will replace the traditional power grids and will be implemented in households cannot be drawn yet. This thesis also contains a practical part in which I create a user interface in Grafana, which is an open-source software for time series analytics. The user interface is created for a Raspberry Pi touch display which has a sensor connected to it that allows us to measure energy consumption of electricity meters. The measured values are then presented in useful graphs and gauges in Grafana, and also on the display itself.

Multi-Conductor Model of Communication over Outdoor Power Lines
Franek, Lešek ; Steinbauer, Miloslav (referee) ; Vozňák, Miroslav (referee) ; Fiedler, Petr (advisor)
PLC - power line communication is not new. It has been known for many years. But It never be used in massive scale. There were only sporadic applications, for example ripple control system HDO used in the Czechoslovakia. PLC currently experiencing a renaissance thanks to the advent of Smart Grid. PLC offering relatively low bit rates and relatively unreliable transmission, but these disadvantages compensates very low costs to build a communication infrastructure and it offers specific functionalities for Smart Grid. The question is whether the declared parameters will be met in the real world. This thesis tries to find an answer.

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.

The framework for application of phase allocation of consumers
Franěk, Vít ; Koudelka, Jan (referee) ; Vyčítal, Václav (advisor)
The aim of this work is to introduce the issue of the smart grids concept, as well as the issue of phase identification sorting from implementation smart grids. The issue of phase identification sorting is described by several possible methods. The work continues by calculating the theoretical network and processing the values measured from the low voltage network and applying the phase identification method based on voltage events. Based on the results, a laboratory task proposal is prepared.

Smart Grid - pokročilé řízení energetických sítí
MAREŠ, Jan
The subject of this master thesis is the characterization of an intelligent networks so-called Smart Grids in the energy industry and the realization of testing scenarios in a power grid simulator. The theoretical part maps the main specifications, communication principles, and architecture of Smart grid. The practical part describes the simulation of the power grid of small suburban area and the effect of electric vehicles and renewable resources on the grid. The results of the thesis are network status assessment and design of steps required for a successful wide deployment of electric vehicles and renewable energy resources.
