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.

Systems for remote measurement in power engineering
Hudec, Lukáš ; Mlýnek, Petr (referee) ; Mišurec, Jiří (advisor)
The work deals with the measurement and management in power. Provides an introduction to the problems of remote meter reading, management, and describes the current situation in the field of modern technologies Smart metering and Smart grids. It also analyzed the issue of collection of networks and data collection from a large number of meters over a wide area. For the purpose of data transmission are described GPRS, PLC, DSL, ... Further, there are given options to streamline communication. This area is used hierarchical aggregation. Using k-means algorithm is a program designed to calculate the number of concentrators and their location in the group of meters. The finished program is written in Java. It has a graphical interface and shows how the calculation is conducted. To verify the results of the optimization program is given simulation model in OPNET Modeler tool. Audited results are described in the conclusion and can deduce that using the optimization program is to streamline communications.

Electricity Meters Utilization for Advanced Monitoring and Control of the Power Distribution Systems
Bernát, Jan ; Pithart, Jan (referee) ; Drápela, Jiří (advisor)
This thesis deals with a research of static meters manufactured nowadays usable in systems of smart metering. Static meters and their functions are described in terms of their internal organization, metrology and wiring. Emphasis is given to the description of new functions (detailed measuring, calendar, disconnector, communications etc.) which could not be used with induction meters and to requirements for measuring, for expenditure control, for safety of meters and for the concept description of smart grids. In a practical part of the thesis particular systems of smart metering will be described – AMR, AMM, AMI and their advantages and benefits during their deployment. The thesis includes also a catalogue of meters usable for smart metering, which is based on available information from particular producers. The final part of this thesis gives information about a pilot project of ČEZ company and about another possible functions of smart meters which could be of use in the future.

Options of network operation with distributed generation sources in island operation
Mareček, Tomáš ; Drápela, Jiří (referee) ; Kopička, Marek (advisor)
This diploma thesis presents managing of the island mode using distributed generation. In the theoretical part of the thesis, the power system of the Czech Republic is described, together with its future development, and future development of installed capacity of distributed generation. Types of distributed generation are also mentioned. Next part of this work is focused on technological parts of islanding operation and its requirements. The following part describes components of the smart grids and mentions some of its functionalities. The practical part of the thesis describes the created models of components in PSCAD programme. From those components two slightly different grid models are created. On those grid models, simulations are made, during which island mode is created. Some of the grid functionalities are tested during those simulations, for example; reaction of the island mode for load increase, load decrease and others.

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.

Demand Management in Smart Grids
Nesveda, František ; Pilát, Martin (advisor) ; Vlach, Milan (referee)
With the rapid adoption of electric vehicles and the rise of power generation from re- newable sources, intelligent management of power demand on a household level is gaining importance. Current algorithms used for that purpose have negative privacy implications and focus only on controlling the charging of electric vehicles while ignoring other ap- pliances. We describe a decentralized algorithm designed to control the power demand of different types of household appliances along with the charging of electric vehicles while preserving the privacy of the subscribers. We also present a smart grid simulator to evaluate the algorithm's effectiveness along with results of simulating a scale model of the power grid of the state of Texas. 1

Implementation of the Smart Metering Systems in Energetics in Slovakia
Petreová, Adela ; Machek, Ondřej (advisor) ; Tyll, Ladislav (referee)
The goal of the Master´s thesis is to map the actual situation of transformation of power energy sector to smart grid, find answers to some of the major questions concerning the implementation of smart metering systems, evaluate societal and economic costs and benefits, evaluate trends in legislation, compare the situation in Slovakia with other peer countries from the European Union, and create a follow-up recommendations for Slovakia based on this assessment. The thesis includes detailed critical analysis of the CBA, originally created for Slovakia, using benchmarking with countries with a different calculation approach. The used methodology in this work is a research of available resources, qualitative research of case studies, break-down of the CBA, and expert research through interviewing. The outcome is evaluation of economic and societal contributions of smart metering systems and mapping the process and state of the implementation.
