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.

Proposal for the Procedure of Supply Restoring for Power Plant Teplárny Brno Auxiliary System after Extensive System Fault in PS
Jára, Jaroslav ; Vaculík, Petr (referee) ; Orságová, Jaroslava (advisor)
This work deals with the issue of supply restoring for heating plant Teplárny Brno, a. s. Špitálka division, after a system-wide failure of the “blackout”. The thesis solves the “black start” of the Špitálka Teplárny Brno operation by delivering a voltage from the hydroelectric power Vír I, proposes a methodology for commissioning of individual devices, up to phasing the generators with subsequent possibility of creating an “island mode” in the area of Brno city, which the work already does not deal with. The work also deals with the preparation of the operational test, while starts of the selected devices are tested. The schedule of commissioning of each device is supported by calculations of the parameters for the entire system with regard to voltage drops while connecting the high load. The result of this work is the proposal of methodological process of supply restoring for power plant Teplárny Brno – Špitálka division, by submission a voltage from the hydroelectric power Vír I, which can be used both in any system-wide failure of the “blackout”, or during the operational test.

Starting the electricity system from the dark with the help of EDU
Puchnar, Jiří ; Fejta, Libor (referee) ; Mastný, Petr (advisor)
This bachelor thesis aims to introduce the reader Blackout exercise, which is run annually on nuclear power plant Dukovany. This exercise simulates a situation when there is a loss of power for own consumption and the steps leading to its recovery. Then it focuses how to troubleshoot electrical grid restoration of the Czech Republic with NPPD. This bachelor thesis is divided into two parts. The first part defines the term Blackout, described the involvement of power plant to national grid, output to a substation Slavětice and near power sources. NPPD appliances are divided into categories according to the importance of power. Their classification and ways of feeding during normal operation and for other situations are described in the third chapter of this work. In my work I present options and recovery routes after power failure for own consumption NPPD. Internal and external. The lack of power can cause the risks described in the fifth chapter. At the end of the first part is an example of one possible method to restore power from an external source. The second part focuses on the renewal of electrical grid with NPPD. It aims to describe the configuration of the transmission system, using of island operation and some specific features related to island operation. In this section, I present also some new possibilities for increase of durability and safety of electrical grid CR NPPD. The conclusion summarizes the meaning of Blackout exercise together with the benefits of this work and some recommendations.
