Optimalization of Power Electric Engineering Processes by Genetic Algorithms
Paar, Martin ; Hradílek, Zdeněk (referee) ; Skala, Petr (referee) ; Toman, Petr (advisor)
Current trends in regulation of electricity supply continuity in the power engineering industry includes introduction of systems and customers standards. The electricity market liberalization in the European Union is speeded up the process furthermore. Companies included in the distribution network bussiness therefore began to be interested more in the evaluation of risks associated with the aplication of these standards. The aim of the thesis is to minimize the expenses caused by power losses of the distribution network by means of distribution network reconfiguration depending on the standard selection. For the minimization two of the Genetic algorithms was selected. As an criterion the overall expenses caused by power losses and the expenses caused by an electricity shortage. Furthermore the influence of the inclusion of the power loss to the calculation on the operation costs for given regulation standards. Two contemporary standards - finish and portugues - are considered together with three experimental standards. The aim of including experimental standards is to complete the regulation standards with parameters uncovered in the portuguese and finish standard. The results described in the thesis can be used in the distribution network optimization process from the point of reliability and operational costs.

Power Losses Calculation Depending on Distribution Network Configuration
Domes, František ; Souček, Jan (referee) ; Paar, Martin (advisor)
This master‘s thesis deals with the calculation of losses depending on the configuration of the distribution network. The first part focuses on the general theory regarding some used calculation methods of steady operation. The next part is theoreticly dedicated to the technical losses, possibilities of their influencing and their calculation. In the practical part is carried out the choice of calculation method of steady operation. This method is implicated into the proposed program in programming environment MATLAB.Furthermore, on the basis of a partial measurement in the distribution network and using the proposed program are determined the sizes of offtakes of mesh network. For the existing mesh network is designed its radial operation. In the last part are calculated the losses of this network for both of these mentioned operations.
