Assessment of the impact of different types of RES in the power system
Zmeškal, Pavel ; Matoušek, Antonín (referee) ; Mastný, Petr (advisor)
This thesis deals with usage of each kind of RES under conditions of Czech republic and their usage at areas placed in. Consequently supplied RES output power at time and its influence on reliability of supply in EPS CZ. Way of operation of RES from point of view of requirement on regulation and control of operation of EPS is more studied on operation of different kinds of wind power plants, which due to its variable output power affects not only EPS CZ. At final caption, economic influence of RES to EPS is reviewed as a unit, increasingly claims on regulation, increasingly benefit on support of RES. All these influences increase price of electricity for end user.

Operational efficiency of photovoltaic generators
Koval, Filip ; Václav, Březina (referee) ; Gregor, Jan (advisor)
Objective of master’s thesis theoretical part is especially to illustrate influence of operation conditions, such as solar radiation, temperature or pollution of photovoltaic generator active area, on load and power characteristics of photovoltaic generator, or more precisely on photovoltaic conversion efficiency. Possible variants of increasing effectivity of using photovoltaic generator are explored, such as solar radiation concentration, photovoltaic generator active area cooling or aplication of optimalization circuit. Pivotal part of master‘s thesis is focused on experimental device practical realisation, concretely type MSQ36-10 photovoltaic generator with oriented concentrators of solar radiation. Practical realisation includes design of master‘s thesis experimental part construction with subsequent design of photovoltaic generator motion cycle necessary for adequate simulation of configuration variants solved using single testing photovoltaic generator. Description of own experimental device construction with list of measuring places used in task takes up. It is used automatic monitoring system working as independent measurement task for required values measuring and consecutive data collecting. It is done in two phases. First phase is measurement of all required values, in second phase measurement with attached optimalization circuit is made. Optimalization circuit sets best working point of photovoltaic generator according to actual working conditions. Master‘s thesis intention is experimental verification of solar radiation concentrators application convenience, orientation of photovoltaic generator or its mutual combination, namely using type MSQ36-10 photovoltaic generator. Objective is evaluation of reached energetic gain for all experimental device layouts in variable operating conditions.

Hydrogen fuels
Umlauf, Martin ; Bébar, Ladislav (referee) ; Jícha, Jaroslav (advisor)
Paper presents a basic review and comparison of energy-conservation made of renewable sources. Principal question of paper concerns evaluation of hydrogen-use made of electrolysis of water. First part of the thesis focuses on the production of energy from renewable sources and the possibility of energy-accumulation. The next section describes methods of hydrogen production and utilization of hydrogen as a fuel for combustion engines. Attention is paid to various aspects dealing with construction of combustion engines using hydrogen. Final part of the study presents comparison between combustion engines using known sorts of fuels as to their pollution and emission-level. Next comparison deals with economic cost per kilometer, when different sort of fuels are taken into account. Conclusion concerns approximate calculation of the production of hydrogen from water by electrolysis using photovoltaic power plants.

Alternative Energy Resources for Family House
Němec, David ; Brázdil, Marian (referee) ; Špiláček, Michal (advisor)
This bachelor thesis is focused at an issue of thermal energy supply for family houses from renewable resources. The aim of this thesis is to provide a summary of possible thermal energy supplies from renewable resources (solar collectors, heat pumps). After that follows a draft and economic evaluation of these systems for individual sources of thermal energy. In introductory section a solar energy is described. It is a significant part of renewable energy. This part is followed by review with description, composition and principle of individual types of solar collectors and heat pumps. Next part is focused on draft of these systems. Conclusion is then dedicated to energy evaluation of individual designed systems.

Effect of geographical location on solar systems performance
Kuljovský, Martin ; Weismanová, Júlia (referee) ; Jaroš, Michal (advisor)
The sharp price increase and the impending depletion of fossil fuels has led to an increasing interest in renewable resources. This thesis deals with one of the most lucrative substitution between renewable sources - the solar energy. The introduction describes the emergence and spread of energy in the universe, then is devoted to basic distribution of collectors and informs about the possibilities of their use. In particular, it contains formulas for calculating the basic performance characteristics and then comparing differences between panels. Finally, it compares the effectiveness of collectors for different geographical locations in the Czech Republic.
