Power line grid model
Csiba, Patrik ; Sláčik, Ján (referee) ; Mlýnek, Petr (advisor)
This diploma thesis analyzes the PLC communications in various scenarios. The first part of the thesis describes the principle of narrowband and broadband communication and the analysis of electrical lines. The next part describes the NS-3 framework, simulation scenarios for establishment the effect of branches and other parameters on the baud rate. The last part determines the minimum number of repeaters and their location on the extended topology.

Investment Optimization
Bujnovský, Daniel ; Bednář, Josef (referee) ; Popela, Pavel (advisor)
This work is focused on description of two models of mathematical programming - the network model and the Markowitz portfolio model, their connection and application in transportation problems. The goal of the practical section is to approach the description of these problems to the real situations and look for their efficient solutions at the same time. All of that is accompanied by examples on real data from capital market or own model data. The theoretical considerations and thoughts are implemented in programming language Matlab. All results are explained in context to both models. The thesis also includes the introduction to economical and statistical theory which is necessary to understand the problem.

Simulation of reliability indices of a 22kV urban distribution network with various outgoing feeder configurations
Semerád, Jiří ; Skala, Petr (referee) ; Blažek, Vladimír (advisor)
This work deals with simulation of the urban distribution network reliability. For the evaluation of these networks are used indicators of reliability which are described in the first part. Next methods of analysis and posibilities for capabilities reliability simulation of distribution network are described. The third part deals with the real value of the reliability of electricity distribution in Italy. These values are presented in tables and graphs. The last part is a simulation of the urban network. Effect of different configurations on the reliability of electricity supply are studied. Sensitivity analysis is done for failure rate and proportional of the number of sampling points; the simulated values are fiven in tables and graphically.

Effect of distributed generation on medium voltage 22 kV distribution system operation with a new 110/22 kV feeder
Konopová, Tamara ; Bráblík, Libor (referee) ; Drápela, Jiří (advisor)
This thesis deals with the issue of power flow analysis in a medium voltage (22kV) distribution network with a focus on the influence of distributed energy generation recources. At first the issue of operation of distributed energy resources and their reverse effects on the distribution system is presented in the thesis. Furtherly there are described their operational conditions from the legislation point of view. The part dealing with calculation compares two network configurations in terms of power quality and how the power quality is impacted by distributed energy resources. The attention is given to voltage conditions, short-circuit power, power conditions, losses and flicker. The first configuration corresponds to the real situation in the network, the other one is describing the changes after the new 110/22 kV substation implementation to the power supply area and the overal change of network configuration. The network model and run simulation is done using the E-Vlivy program.
