Feasibility study pumped storage hydropower plant in a particular locality
Vaněk, Michal ; Štigler, Jaroslav (referee) ; Hudec, Martin (advisor)
Electric energy storage represents an area, which needs to be further developed in order to accommodate more installed capacity of wind and solar power plants in the electric grids. Pumped hydro energy storage still remains ahead of other storage technologies in terms of achievable storage capacity. However, environment protection which is one of the obstacles for further PHES development in Europe causes significant reduction of suitable sites. It is therefore useful to examine also those sites, which seem to be less favourable for PHES at the first glance. This thesis deals with a feasibility study of a PHES on place of a former graphite surface mine. The thesis includes computation of basic capacities, choice of a suitable machine arrangement and introduction into PHES feasibility issues in electric grids. Two possible solutions of a smaller PHES that differ in their capacities were suggested based on available materials about the site as well as on available materials from Francis pump turbine model research. In case of both solutions a binary machine set is used and the available capacities are in small tens of megawatts. However, there is a wide head variation at the site, which causes significant power variation. Concerning the feasibility of the PHES, it is very uncertain that the participation in the day-ahead electricity market, would provide enough revenue to cover operation and capital costs. A following economic analysis investigating the capital costs of this particular PHES would be beneficial, as well as more detailed design of the reservoirs.

Electricity storage with Power to gas
Bartlíková, Zuzana ; Pospíšil, Jiří (referee) ; Baláš, Marek (advisor)
This diploma thesis deals with accumulation of electricity energy using power to gas technology (P2G). The thesis is divided into two parts. The first part describes the whole system from the production of electricity, through water to the production of hydrogen by available technologies and possibilities of using hydrogen. For individual parts of the P2G system are described their operating conditions, advantages, disadvantages and efficiency. The second part of the thesis is practical. Several possible uses of hydrogen produced and the efficiency result of these P2G systems are determined. Finally, there is one use of the hydrogen produced which is compared from the energy point of view with the system that is currently used to store electricity.
