Decentralized collection and treatment of wastewater from settlements up to 200 PE.
Petřík, Jiří ; Raček, Jakub (referee) ; Hlavínek, Petr (advisor)
The aim of this bachelor’s thesis is to outline the issues of a decentralised system of drainage. The theoretical part of the bachelor’s thesis is processed in the form of research and focuses mainly on the possibilities of disposal of sewage and rain waters. Describes the possibility of using the treated sewage effluent, the possibility of delaying the rainwater at the place of deposition and their use. In this bachelor’s thesis is also listed technology related with this issue. In the practical part of the bachelor’s thesis deals with the proposal of the technical-economic study of a decentralised system of drainage of the municipalities Koberovice, Lísky and Lohenice, which are located in the cadastral territory of Koberovice in the district Pelhřimov.

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.

Wind power generation and energy accumulation possibilities
Krbal, Michal ; Mastný, Petr (referee) ; Drápela, Jiří (advisor)
The goal of this bachelor’s thesis is to inform about conditions of running and the character of running of the wind power plants and about the suitable storage systems for the possibilities of time invariableness of power supply. For these reasons is immediately in the first chapter of the thesis described state of using wind power plants in The Czech republic and other countries in Europe which produce electric power. Description of individual functional parts is important mainly from the point of electrician conversion of kinetic energy of wind to electric energy with help of the electric power generator with the highest efficiency and without need for maintenance. It is necessary to know those functional parts of the power wind to be able to design appropriate storage system. The output electric power is very variable at time, mainly output voltage, because wind energy is variable too. The characteristics of the wind power plants as output voltage, frequency and their switching graded at time have to in accordance with requirements of the electricity supply systems not to disturb the stability or even collapse of the electricity supply system which would lead to serious economic consequences. These predicaments can be prevented with precise meteorological forecast or by using the acceptable storage system with small acquisition and operating costs, requirements to safeness and long service life, low weight and high efficiency of conversion of energy. The storage systems are classified into centralized and decentralizing systems with requirements to dynamic running and running time. To fulfil these conditions it is essential to choose acceptable and accessible locations with year lasting qualities of wind, which are being checked in advance using measurement and mathematical calculations.
Heat storage in solar thermal systems

Technologies for electricity storage
Novák, Adam ; Lisý, Martin (referee) ; Škorpík, Jiří (advisor)
This project deals with description of individual ways of electric energy accumulation. Accumulation itself becomes an essential part of the electricity grid due to rising electricity fluctuations from renewable sources and uneven consumption from users. For each technology, the principle of functioning and the advantages or disadvantages are explained. Based on this informations, it is specified suitable application. At the end, the state-of-the-art technology and modern equipment for storing electricity are presented.
Accumulation of energy
Neuman, Tomáš ; Kloss, Ondřej (referee) ; Kaplan, Zdeněk (advisor)
This bachelor thesis comprises a technical retrieval of overview of energy accumulation usable in cars. The basic characteristics and problems of particular kinds of accumulators and ways of accumulation are brought in this thesis, describing characteristics of lead accumulator, the structure and composition of electromobiles and appropriate batteries. In the following part the description of heat and hydrogen accumulator is stated. The end of this bachelor thesis is dedicated to mechanical accumulator.
Possibilities of Accumulation in Distribution Network
Žižlavský, Jakub ; Pěcha, Jiří (referee) ; Mastný, Petr (advisor)
The Bachelor thesis on the Possibilities of Accumulation in Distribution Network focuses on the distribution of electric energy storage types. Then the most suitable candidate for the application of the accumulation of electricity in the distribution network will be selected and further work will be conceived according to the choice.
Technologies for electricity storage
Pochylý, Jiří ; Kracík, Petr (referee) ; Škorpík, Jiří (advisor)
The point of this work is to compare and to describe basic types and principles of electric storage systems. With the increasing imbalance between consumption and generation of electric energy there is a need for integration of electric accumulators to the electric grid. Technologies for electric energy storage can be divided into several types, which differ in form and conversion of energy. These technologies are suitable for specific industrial applications.
