Use of compressed air energy storage
Laca, Theodore Nicolas ; Charvát, Pavel (referee) ; Štětina, Josef (advisor)
In the search part is elaborated a basic overview of the importance and benefits of electricity storage. It describes the main possibilities of electricity storage, divided by the form of storage. It includes knowledge of thermodynamics in compression and expansion of ideal gas (air). It briefly describes practical applications of compressed air. Further, it focuses on compressed air energy storage (CAES). It contains a basic simulation of the compressed air engine. The conclusion deals mainly with the prospects of using CAES.

Model of Bulk Energy Accumulation
Radil, Lukáš ; Barath, Peter (referee) ; Gregor, Jan (advisor)
The purpose of this pursuit is to introduce the reader about the questions of the accumulation of the electric energy and to outline possibilities of its design and what instruments is possible to get it. The other purpose is to inscribe possibilities of today´s attachment of dispersive sources to the net from the sight of the ERU, eventually from the sight of the UCTE. This persuit describes the posibility of the accumulation of adequate dimensions from renewable resources, the modern trends in this area and the prediction of future progress. The two most proper types of the energy accumulation are chosen by the following process with regarding to the optimal resolution of the given questions. The general balance will be ana-lysed by the comparison of their basic parameters. The other point of this pursuit is to try to realize a small model of the accumulation through the hydrogen´s cycle, it comes to that we can develop the efficiency and influence by the help of the electrolyzer and the metalhydride reservoir is realized energy of accumulation . In the conclusion of this pursuit is the appreciation of the whole project with the view of partly economical and especially with the view of the prospective usage into the electric grid

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.

Solar charge controllers for off-grid systems
KRČKA, Pavel
This diploma thesis deals with photovoltaic rechargable regulators used in isolated, or off-grid photovoltaic systems. First, basic types of off-grid installations, including their functions and applications in practice are described. Then, possibilities of electric energy accumulation in photovoltaic systems are mentioned, considering actual, accesible technologies. Matters of electric energy accumulation in leaden accumulators are examined in detail. Main part of the diploma thesis is about electronic designs of photovoltaic, also called solar, rechargable regulators. These are the main connecting part between photovoltaic panels, accumulator, but also often connected charge, which is appliance. Individual electronic regulators concepts are described narrowly, then compared and evaluated in thesis´ conclusion.
