Different use of the wind energy.
Sukup, Jan ; Houdková, Lucie (referee) ; Jícha, Jaroslav (advisor)
This thesis describe main kinds of wind turbines, principle of their functions and their usage to electricity generation. The second part deals with ways to storing wind energy. There is description of compressed air energy storage technology and their combination with combustion of biomass. Second mentioned energy storage technology is electrolysis of water and possibility of usage hydrogen.

The underground pneumatic energy storage
Pochylý, Jiří ; Škorpík, Jiří (referee) ; Fiedler, Jan (advisor)
This diploma thesis deals with the underground compressed air enery storage. Thesis can be divided into several parts. The first part focuses on the theoretical analysis which decribes reason of renewable resources implementation to the electric grid and how renewable resources affect electric grid. Second part describes compression and expansion stage. Last part deals with design of storage facility which is suitable for different energy supplies. Extracted coal mines of Rosicko-Oslavany area is used as suitable underground storage.

Use Compressed Air to Electric Power Accumulation
Martinák, Rostislav ; Radil, Lukáš (referee) ; Baxant, Petr (advisor)
The aim of this paper is to acquaint the reader with the possibilities of using the energy of compressed air in different areas, but particularly with the use of compressed air to accumulate electrical power. This paper introduces the technologies they use to their function pneumatic tools, compressed air car and compressed air energy storage facilities. The next section is to compare the compressed air energy storage systems with some accumulation possible ways of electrical power. The conclusion sums up work opportunities to accumulate electrical energy in compressed air.

Wind power generation and energy accumulation possibilities
Krbal, Michal ; Mastný, Petr (referee) ; Drápela, Jiří (advisor)
The goal of this bachelor’s thesis is to inform about conditions of running and the character of running of the wind power plants and about the suitable storage systems for the possibilities of time invariableness of power supply. For these reasons is immediately in the first chapter of the thesis described state of using wind power plants in The Czech republic and other countries in Europe which produce electric power. Description of individual functional parts is important mainly from the point of electrician conversion of kinetic energy of wind to electric energy with help of the electric power generator with the highest efficiency and without need for maintenance. It is necessary to know those functional parts of the power wind to be able to design appropriate storage system. The output electric power is very variable at time, mainly output voltage, because wind energy is variable too. The characteristics of the wind power plants as output voltage, frequency and their switching graded at time have to in accordance with requirements of the electricity supply systems not to disturb the stability or even collapse of the electricity supply system which would lead to serious economic consequences. These predicaments can be prevented with precise meteorological forecast or by using the acceptable storage system with small acquisition and operating costs, requirements to safeness and long service life, low weight and high efficiency of conversion of energy. The storage systems are classified into centralized and decentralizing systems with requirements to dynamic running and running time. To fulfil these conditions it is essential to choose acceptable and accessible locations with year lasting qualities of wind, which are being checked in advance using measurement and mathematical calculations.
