Diploma thesis deals with the issue of statistical reporting Energy regulátory office ČR. The introduction describes the contents regularly published reports on the operation of the electricity system in the Czech Republic. In the thsis deals with the analysis of statistical reports. Processing code in Python and describes its implementation in analytical platform KNIME.

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
