PV plant performance evaluation and optimization
Špinar, Marek ; Ptáček, Michal (referee) ; Morávek, Jan (advisor)
The Master´s thesis deals with issues of operational performance of two photovoltaic power plants. In the thesis is stated the history of photovoltaics, description of photovoltaic effect, used materials and production technology of the most used material in PV industry – Silicon. The basic parts and parameters of photovoltaic power plant are described. Thesis also solves, how could be done the first and periodically control due to relevant directives. The ways of diagnostics potentional failures, methods of measuring and the exam of monitoring system are stated. Practice part is focused on measuring and comparing operational performance of FVE Kurdějov and FVE Šakvice II. Operational performance was calculated from exported data for years 2014 and 2015. The thesis also contains measuring of each string connected to inventors, which are installed on the power plant. The result is an identification of strings with decreased operational performance. Based on that was created recommendations for optimalization and increase of the performance. The last part is software for simulation of photovoltaic power plant. This SW calculates potentional energy, which could be produced in a day with available data export. The calculation is defined by parameters, which are assigned.

Influence of Wind Power Plants on Voltage Stability in Continental Europe
Herůfek, Radek ; Morávek, Jan (referee) ; Mastný, Petr (advisor)
Diplomová práce pojednává o výrobě elektrické energie větrnými elektrárnami a jejím vlivu na napěťovou stabilitu v synchronně propojené elektrizační soustavě kontinentální Evropy. Úvod práce je obecně zaměřen na problematiku větrné energetiky se zaměřením na nejčastěji používané generátory pro větrné turbíny. V další části práce je proveden rozbor instalované kapacity větrných elektráren v zemích synchronně propojené elektrizační soustavy kontinentální Evropy a jsou představeny scénáře růstu větrné energetiky do budoucna. V rámci těchto zemí je také zařazen přehled potenciálu větrné energie na pevnině a na moři. Dále je práce zaměřená na napěťovou stabilitu, kde je pojednáno o kompenzačních prostředcích a možnostech regulace napětí. Závěr teoretické části je věnován možnostem předpovědi počasí a dopadu změn počasí na výrobu elektrické energie. V praktické části diplomové práce byla provedena simulace plánované větrné farmy a sledování jejího vlivu na napěťovou stabilitu v konkrétní části přenosové soustavy.

Proposal for house backup energy source
Ličman, Petr ; Morávek, Jan (referee) ; Baxant, Petr (advisor)
This master's thesis deals with a design of backup power system, which will be using renewable energy sources, particularly solar energy. The first part describes the potential of solar power plant in the Czech Republic. The next parts describe types of photovoltaic systems, their components, design of photovoltaic systems and possibilities of controlling power consumption. Due to the fluctuating supply from renewable energy sources the thesis also deals with possibilities of predicting of the production electricity from these sources. In the practical part the design of backup power system for the house is done, which will also be working in summer as an optimizer for own consumption. A financial evaluation was done for this proposal.
