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.

Actual State and Potential of Renewable Sources Utilization in the EU
Kubín, David ; Radil, Lukáš (referee) ; Macháček, Jan (advisor)
This bachelor’s thesis named Actual State and potential of renewable sources utilization in the EU offers a detailed summary of the current and future utilization of renewable resources in each member state of the European Union. The opening chapters briefly introduce the term renewable resources and the legislation relating to this issue. The following chapter is devoted to a detailed background research of actual renewable energy utilization in all twenty seven member states of the European Union. The countries are ranked by their dates of accession to the Union in ascending order, in each chapter alphabetically. All information and data are obtained from reliable sources such as annual energy reports of ministries or institutions which are concerned with energy issues. This chapter contains a great amount of charts and tables taken from annual reports and which are revised for the needs of this thesis. The chapter named Potential of renewable energy utilization in the EU offers an insight into the assumed future utilization of renewable resources up to the year 2020. This chapter draws from so-called National renewable energy action plans (NREAP) in which each member state presents its plan leading to higher renewable sources utilization in the near future. The reader is therefore able to familiarize with plans concerning renewable sources in each member state. The chapter named Complex evaluation familiarizes with some pros and cons concerning renewable sources and their utilization. Further the author presents his point of view on renewable sources and some recommendation leading to a better integration of renewable sources into energetics.

A study of small water power resource
Demovič, Petr ; Pěcha, Jiří (referee) ; Matoušek, Antonín (advisor)
This Bachelor thesis deals with a concept of a small hydro power plant. The first part is focused on hydro power potential of the Czech Republic, the general theory of small hydropower plants and their division. The following part discusses about the selection of suitable localities for construction of small hydro power plant and the decision of choosing the best of them. The selected locality is described and evaluated. Subsequently, the thesis deals with the theory of water management and hydro power solution of small hydro power plant. As the next step was to design the most suitable turbine. Then the thesis characterizes the concept of electric part of the small hydro power plant and its connection to the distribution network. This part is focused on the design of the most suitable generator, compensation of reaktive powers, a concept of cabel for pulling of power of power plant a protections. The last part is about economic evaluation of the entire investment and environmental evaluation.
