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.

Regulation options of renewable energy sources
Pavlíček, Jiří ; Morávek, Jan (referee) ; Pěcha, Jiří (advisor)
This bachelor's thesis deals with the regulation of renewable energy sources. It focuses on ways of managing and possibilities of regulation renewable energy resources. Indicates the proportion of various types of renewable energy sources in electricity production and their representation in the electrical load profile. Thesis describes the various storage systems, which can be used to stabilize the renewable energy sources. Evaluate the applicability of these storage systems in the energy sector.

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 grids - smart grid for energy
Kapoun, Vladislav ; Mlýnek, Petr (referee) ; Mišurec, Jiří (advisor)
This bachelor thesis is aimed at the analysis and the description of Smart Grids within the field of power engeneering. It deals with Smart Grids´ general requirements and their practical application. Furthermore, it discusses Smart Grids´ security measures, and describes its components. It also draws up intelligent household, selects and theoretically applies components to pre-selected object. The bachelor thesis further encompasses a network simulation whose graphs show channel transmissivity among concentrators while data are simulated.

Pilot testing of LoRaWAN technology in disconnecting fuse boxes
Benešl, L. ; Mlýnek, P. ; Harman, D.
This article deals with the concept of Smart Cities concerning Smart Grids. As part of Smart Grids and secondary metering, there is also the lifespan of the devices that are deployed in distribution companies. This also applies to switch cabinets, disconnecting fuse boxes (DFB), and other elements that are made of a material that can degrade due to adverse weather conditions. For this reason, secondary temperature and humidity measurements have been introduced. During the measurements, temperature extremes were recorded, which could reach more than -10 °C in winter months and almost 45 °C in the warm months. Humidity could reach up to 100 % in some cases. Another monitored parameter was the successfully received messages, where LoRaWAN technology reached almost 95 %.

Proposal of measures in the low voltage network for the implementation of renewable sources and electromobility according to scenarios NAP SG
Vojtěch, Jan ; Kučera, Michal (referee) ; Ptáček, Michal (advisor)
The thesis analyzes legislative and strategic documents of the European Union and the Czech Republic which set targets in environment and energy area in 2030, alternatively in 2040. The individual chapter is dedicated to national action plans, where the most important is National Action Plan for Smart Grids setting specific requirements for future development of smart grids. The thesis contains analysis of distribution network in the municipality of Následovice and simplifying assumptions for the implementation of calculation. There are also introduced scenarios which have been used for the calculation of the distribution network with its results. Potential defects of the distribution network are commented with suggested solutions. The calculations were repeated to verify the solutions. Results are recapitulated in an individual chapter. Graphical outputs of the calculations can be found in the attachement.
