Realization of a smart meter
Cu, Lukáš ; Mlýnek, Petr (referee) ; Lieskovan, Tomáš (advisor)
This thesis deals with the issue of smart metering, specifically electricity metering. It introduces the reader to the basic concepts associated with it and describes the technology used to implement such an electricity meter. The practical output of this work is a real smart electricity meter made of a singleboard platform Raspberry Pi 3 B, the Arduino platform and two external modules for measuring the state of electrical network. These modules are current sensor SCT-013-000 and a voltage sensor ZMPT101B. The software solution for controlling individual components and for working with the data is implemented using a combination of code created specifically for this purpose and of code from an external library belonging to Gurux company.

DLMS concentrator simulator
Buš, Ondřej ; Šilhavý, Pavel (referee) ; Lieskovan, Tomáš (advisor)
This work is focused on a field of smart metering and data concentrators. The first part of this paper describes the DLMS/COSEM specification. The first section contains DLMS protocol specification, the process of communication between devices and services that allows data communication. COSEM classes and objects can be found in the second section. These objects are used to access a specific data stored inside smart meters. Lastly, there is an section that is focused on OBIS objects which are used for addressing. In the second part, the concentrator's basic functionalities are described. These functionalities include device management and configuration file storage. The last part then focuses on a web server. The web server allows a user to manage the concentrator by adding, editing and removing connected smart meters.

Smart meter simulation on KYPO platform
Morawiec, Daniel ; Gerlich, Tomáš (referee) ; Lieskovan, Tomáš (advisor)
This bachelor thesis is focused on problematics of smart grids, smart meters and protocols which are used in the energy industry. The part of thesis is dedicated to DLMS protocol and COSEM specification. Cloud platform OpenStack and cyber range platforms, more specifically KYPO CRP, are subsequently described in this work. In the last part of the bachelor thesis deployment of platforms OpenStack and KYPO CRP is executed and testing scenario with common elements of energy networks is commissioned on the platform KYPO.

Design of a smart meter testing methodology focusing on invasive testing
Biolek, Martin ; Sikora, Marek (referee) ; Lieskovan, Tomáš (advisor)
Bachelor thesis is focused on investigating the security deficits of smart meters through penetration testing. The theoretical part describes the standards that should be followed by smart meter manufacturers. This is followed by the practical part where the testing of two smart meter systems was conducted in order to discover their vulnerabilities. The result of the work is the exposure of one of the two systems of interest that requires significant security improvements before deployment of another version. A description of the vulnerabilities is included in the practical part of the thesis.

DLMS security suite implementation
Kohout, David ; Sláčik, Ján (referee) ; Mlýnek, Petr (advisor)
This thesis is focused on smart meters cyber security using DLMS Security Suite standard. Security is more important every day and DLMS specifies multiple methods of authentication and message encryption which is defined in Security Suites. For message creation there are multiple possible formats that can be used. For a better understanding all formats are analysed and compared using a specific example. Main part of this work is about making a testing application called VUT DLMS Tester which is used for testing this standard for real usage in distribution network. Whole development is cooperated with distribution companies and smart meter manufacturers. Application also implements higher levels of security which DLMS specifies. This application is used for testing multiple scenarios regarding security impact on data volume.
