Pump storage station
Šimek, Petr ; Sloupenský, Zdeněk (referee) ; Kubálek, Jiří (advisor)
This bachelor thesis deals with the functions of hydro-power plants, describes the various machinery and their distribution according to the parameters of use. Outlines the calculation in the design of hydraulic machines. There are also descriptions of machine layout and their use in praktice. For the particular case, there is prepared hydro power plant Dlouhé stráně. Related topic that is included here, the electricity system and the daily load diagram.

Real potential of renewable energy sources in Czech republic
Tofel, Jan ; Kropáč, Jiří (referee) ; Máša, Vítězslav (advisor)
The aim of this thesis is to present the basic characteristics of renewable energy sources and assess their potential for further use in the Czech Republic. Based on studying literature, statistics, foreign experience and consultation with experts is reviewed which of these resources in the Czech Republic give meaning or how to ensure their effective use. The individual chapters of the thesis describe in detail the characteristics of renewable energy and in the final chapter are reviewed economic and environmental terms.

Control of decentralized energy sources and storage systems
Maksimovich, Valeriia ; Wannous, Kinan Hasan Wafaa (referee) ; Šedrlová, Magdalena (advisor)
Žijeme ve století, ve kterém jen těžko dovedeme představit život bez elektrické energie. Vznikajicí malé elektrárny, které vyrábějí elektřinu z obnovitelných zdrojů energie vyvolali potřebu v přisnějším řizení, inteligentním měření a změny Evropského trhu s elektřinou. Hlavní otázka spočívá v tom, jak zajistit spolehlivé, bezpečné a udržitelné dodávky energie a současně minimalizovat náklady a znečištění životního prostředí. Jedním ze způsobů je integrace decentralizovaných zdrojů energie do sítě. Tato práce se zabývá konceptem decentralizované výroby energie, paralelním provozem s distribuční sítí, akumulací a pokročilými způsoby řízení zdrojů. Práce také poskytuje přehled účastníků trhu s energií, jako jsou napřiklad obchodníci s elektrickou energií, agregátoři a lokakní distribuční soustavy.

Accumulation of Energy from Renewable Energy Sources
Heller, Ondřej ; Radil, Lukáš (referee) ; Mastný, Petr (advisor)
The objective of the first part of master’s thesis is mapping the potential of various types of renewable sources in Europe and Czech Republic, especially solar energy, wind energy, water energy and biomass. There are described principals and ways of energy generation from these sources, brief overview of current technologies, and also their advantages and limitations. An important part is electric supply continuity from renewable sources, there are large differences and the resulting to restrictions on construction and connecting the units to the power system. In this work there are mentioned some impacts on network and rates of change of supply, some sources are also evaluated in terms of maximum power, that can be connected to the power system in our country. The conclusion of the first part is dedicated to energy storage technologies, which are suitable and usable for renewable sources, there are described their principals, properties, status of development and types of aplications, in which these technologies are used. This chapter also focusses on the price level of each technology. The second part of the thesis deals with 1 MWp on-grid photovoltaic power plant design. This design includes also the redox flow batteries accumulation, the first variant calculates on 24-hour steady energy supply, the second optimalized variant calculates on daily energy supply. There are the accumulation system costs estimated and also the payback period for the both variants. Additionally there is also determined minimum penalization for cost-effective operation. The last part is dedicated to changes of impact on the local grid and changes of system impacts, after the accumulation system is installed.
