Accumulation of electricity for a source with unstable production
Petrenec, Jan ; Milčák, Pavel (referee) ; Pospíšil, Jiří (advisor)
This diploma thesis deals with possibilities of accumulation of electricity generated by renewable sources with unstable production. Several goals were set by an assignment of this thesis. Within a research, current trends of the accumulation are presented in detail on examples of specific representatives with their technical parameters and economic possibilities. Further, an unstable source of electricity – the wind farm of three power plants Multibrid 5000 with all its parameters and operational details is defined for purposes of individual designs of accumulation systems. Firstly, the detailed design of an advanced compressed air energy storage (A-CAES) is realized. It includes a thermodynamic calculation of chosen components, their partial technical solutions, a financial evaluation of investment and a determination of theoretical payback period. Furthermore, the design for accumulators Tesla Powerpack is realized. It contains a calculation of individual system parameters, a financial evaluation of investment and a determination of theoretical payback period. Last part of the thesis is dedicated to a comparison and an evaluation of the achieved results of both realized methods of the electricity accumulation. In the end, A-CAES is chosen as more perspective variation.

Compressed-air energy storage
Strnad, Jan ; Mauder, Tomáš (referee) ; Klimeš, Lubomír (advisor)
The bachelor thesis is focused on the problematics of compressed air energy storage. It includes a short introduction to the thermodynamics of ideal gases. The suitable geological conditions for the selection of CAES (compressed air energy storage) systems, the advantages and disadvantages of each type, the method of their production, and the process of compressed air accumulation itself were discussed. The thesis presents individual diagrams of compressed air power plants, and special attention is given to the description of the accumulation process. The last section is focused on the description and comparison of two built CAES systems working on an identical concept and also presents information on the unrealized planned CAES systems.
