Electric meter simulator with DLMS protocol
Tsymbal, Kateryna ; Gerlich, Tomáš (referee) ; Lieskovan, Tomáš (advisor)
This bachelor thesis is focused on getting acquainted with the DLMS/COSEM protocol and its functions. Furthermore, the Java programming language and the Raspberry Pi minicomputer are briefly introduced. The DLMS/COSEM protocol is used to simulate measurements using a smart meter, which ensures communication between the meter simulator and the concentrator. Communication provided by the DLMS/COSEM protocol is widely used in smart grids. The first part of the thesis discusses important information about energy networks and their relationship with smart meters, the importance of smart meters in modern networks and the role of smart networks, which are used for effective energy measurement in a particular area (e.g. for measuring electricity). Data measured in smart grids can be easily analyzed and used to make consumption more effective. The first part also mentions important information about the DLMS/COSEM protocol, the Java programming language and the Raspberry Pi minicomputer. In the second part of the thesis, a test environment is created for testing the smart meter simulator, which communicates using the DLMS/COSEM protocol with the concentrator and transmits the measured values to it. Measured values are manually defined for testing purposes using code changes in the Eclipse IDE. The aim of the work was to create a smart meter simulator that lists predefined values and passes them to the concentrator, which was achieved using the Gurux.DLMS library. Finally, an analysis of this communication was performed using Wireshark. This bachelor thesis is useful for a simple understanding of the DLMS/COSEM protocol and its use in smart grids.

Pilot project on flexibility management at LV level
Sýkora, Jan ; Pilař, Martin (referee) ; Radil, Lukáš (advisor)
The thesis deals with the topic of flexibility, especially on the demand side. It includes the definition of terms related to the issue, the basic principles of operation and possibilities of use. The main researched branch of the study is the usage of the flexibility potential of heat pumps. The work is based on real data from a pilot project executed in the winter of 2021/22, which examines the portfolio of households with a heat pump and observes the possibilities of using flexibility, its management and especially the impact on load change depending on the estabilished baseline.

Implementation of IoT communication technologies in NS-3 simulation tool
Rehberger, Marek ; Mašek, Pavel (referee) ; Juráň, Radovan (advisor)
The bachelor thesis deals in its theoretical part with LPWA communication technologies in the licensed frequency spectrum, specific technologies LTE Cat-M1 and NB-IoT. The theoretical part summarizes the terms concerning to LPWAN (Low Power Wide Area Network), licensed and unlicensed technologies, SmartGrids, NB-IoT and LTE Cat-M1. The use of LPWA technologies in the field of SmartGrids is described and the idea of Smart Metering in buildings is used in the work. Subsequently, in the practical part for the LTE Cat-M1 technology, the implementation of communication scenarios for data transmission within SmartGrids is performed using the tools Network Simulator 3 (NS-3) and the LENA module. The results of the simulations are clearly processed in the form of graphs and tables.

Smart Cities
Soldán, Michal ; Sedláček, Pavel (referee) ; Marcoň, Petr (advisor)
Tato bakalářská práce se zabývá obecným úvodem do dílčích projektů, které jsou důležité pro realizaci chytrých měst i v nich používaných technologií. Podrobněji tato práce přibližuje projekty v různých zemích, hlavně však v Japonsku a na Havaji. Konkrétně shrnuje technologicky pokročilé energetické řešení a testovací projekty chytré sítě, které jsou základním kamenem pro budoucí chytrá města i efektivní využití elektomobilů. Práce také zmiňuje projekty chytrých měst v Evropě, kde je synchronizace vyvinutých technologií testována v praxi.

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.
