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.

Student zodpověděl otázky oponenta ke své závěrečné práci. Dále reagoval na následující otázky komise: Jak je zajištěno konstantníího tlaku v kaverně? V důsledku čeho se mění tlak v nádrži na termoolej? Co je myšleno kladnou regulační energií? Je to regulace frekvence? Z čeho je zhotovena kaverna? Umí regulaci frekvence nějaká z technologií Tesla Powerpack nebo A-CAES? Student odpověděl na otázky oponenta a na všechny otázky komise. Komise se shodla na hodnocení výborně, A.
