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

This diploma thesis is specialized on problems of electrical energy accumulation from renewable resources. This renewable resources used in Czech Republic are described in the first part. Next, in the second chapter is identification with principles of electrical energy accumulation. In the third part, there is a proposal of electrical energy accumulation system which makes a supply of electrical energy from photovoltaic system by the help of accumulation system in compressed air equally. In the final part, there is a total analysis of technical economic aspect for proposed system.

The diploma thesis is focused on problem of accumulating electric energy from renewable resources. The first section describes renewable energy sources, which are possible to use in the Czech Republic and principles of accumulating electric energy. In the following section are suggested systems of accumulating energy to accumulators by compressed air and pumped storage power station. These systems are proposed for uniform power supply from photovoltaic power station to electric power network all day. In conclusion, the suggested systems are compared from economic-technical perspective.

In this thesis I deal with problem of power acumulation from renewable energy sources. First part present the available technologies used for power accumulation. In the second part is designed the systém of acumulation in compressed air with a transformation electric output 1 MW, when is used made elektricity from wind-power plant. In the third part is an assessment in terms of both technical and economic comparison with the use of electicity from the network.

Presented work deals with appropriate ways of storing thermal energy and selection of materials for a high capacity storage unit. The thesis describes technologies currently used for long-term storage of thermal energy, the structural arrangement of the thermal unit, physical properties of the materials usable for construction of high-temperature storage units and the utilization of these materials. The thesis also describes the measuring procedure of the material characteristics and the method of evaluation. Size of the solar collector and the required volume of the storage for heat supplying of the selected building in the climatic conditions of the Czech Republic were designed.

The master thesis is a research about the relationship between memorials and light. It first studies the characteristics of cultural memories and tries to find what the advantages of using lighting as a means of commemoration are. The nowadays memorials are very different compared to the traditional monuments and they should include a changing narrative, treating local and universal messages. They should involve the public.A contemporary memorial is ephemeral and continuously changing- the same as light is.A series of contemporary memorials have been selected to understand the tools that makes them successful. Furthermore, it was analyzed how these parameters could be achieved through light. 12 memorials that use light as an eloquent tool have been interpreted according to certain criteria.The second part of the thesis is an applied project related to the events that happened in Timisoara, Romania, in 1989 during the anticommunist Revolution. The process of creating memorials for Timisoara is a key focus of the study. The development is equally important as the end result. It searches for the significant messages and lessons of the event. Testimonials of the participants to the revolution have been studied. Interviews and questionnaires have been developed. Following this, significant places in the city and messages were chosen. The research will conclude with a lighting installations project proposal.

This diploma thesis deals with photovoltaic rechargable regulators used in isolated, or off-grid photovoltaic systems. First, basic types of off-grid installations, including their functions and applications in practice are described. Then, possibilities of electric energy accumulation in photovoltaic systems are mentioned, considering actual, accesible technologies. Matters of electric energy accumulation in leaden accumulators are examined in detail. Main part of the diploma thesis is about electronic designs of photovoltaic, also called solar, rechargable regulators. These are the main connecting part between photovoltaic panels, accumulator, but also often connected charge, which is appliance. Individual electronic regulators concepts are described narrowly, then compared and evaluated in thesis´ conclusion.

The thesis discuses an integration of photovoltaic power stations to electric network. The first part describes connecting conditions of small sources to distribution system, including administrative requirements, feasibility study, and requirements to the energy meters, measuring, control devices, switching devices and protection. The second part is aimed to describe problems of the photovoltaic system. Solar radiation generating and reducing of its intensity incident upon the earth surface are described in this part. The quantum of produced electric power depends on climatic conditions in the fixed area, seasons, etc. This work also discusses the types of photovoltaic cells and their actual efficiency. Inverters are further important components of the photovoltaic system. The parameters of the inverters have a great influence on the total actual efficiency of the photovoltaic system. Different methods of the photovoltaic panels’ connection with the inverters and their advantages and disadvantages are also mentioned. The supporting structure of the photovoltaic panels and eventually transformer are further important components of photovoltaic system. The work also analyze the methods of connection of the photovoltaic power station to distributive low voltage and medium voltage network, electric energy accumulation and possibilities of the sale of produced electric energy. The large number of the connected photovoltaic power stations has negative influences to electric network. The third part contains the design of a photovoltaic power plant with a capacity of 516,24 kWp on the scoped area in southern Bohemia. The project documentation for the location where the power plant is designed is also made. It contains the design of photovoltaic panels, the design of the inverters to get an optimal power load. This part also contains a calculation of the photovoltaic system losses and the design of transformer and the cable junction calculation of the distributive system. The feasibility study of the power plant connected to distributive system is also conducted. Its delivery rate will be connected to the distribution point Řípov (110/22 kV). The calculation results show us that this photovoltaic power plant can be linked to the distribution system. The final part of this paper contains an economic estimate of the photovoltaic power plant operating and the calculation of the return. An Economic return is influenced by the wide range of values that affect the total return rate. The calculation of an operating economy is made for several variants. The return rate in refer to contemporary redemption price for 2010 with no consideration for a bank loan is 7 years. If we consider the bank loan it would be 12 years. The penetrative reduction of the redemption price is expected for 2011. Calculation works with the decline of 30 %. It would extend the rate of return to 11 years without a bank loan or to 22 years with the bank loan. The bank loan is considered to cover 80 % of the investment.
