Proposal for house backup energy source
Ličman, Petr ; Morávek, Jan (referee) ; Baxant, Petr (advisor)
This master's thesis deals with a design of backup power system, which will be using renewable energy sources, particularly solar energy. The first part describes the potential of solar power plant in the Czech Republic. The next parts describe types of photovoltaic systems, their components, design of photovoltaic systems and possibilities of controlling power consumption. Due to the fluctuating supply from renewable energy sources the thesis also deals with possibilities of predicting of the production electricity from these sources. In the practical part the design of backup power system for the house is done, which will also be working in summer as an optimizer for own consumption. A financial evaluation was done for this proposal.

Concept of Fast Charging Station with Accumulation for Electric Vehicles
Miškovský, Ján ; Morávek, Jan (referee) ; Mastný, Petr (advisor)
Main purpose of the thesis is the creation of a concept a fast-charging station associated with accumulation that uses renewable source. The introduction of the thesis describes a standard that specifies the charge of electric vehicles using direct and alternating current as well. It depicts an overview of using charging connectors. The first part also deals with overview of the technology of renewable sources and exploitation energy storage system for charging station. The second part introduces the theoretical basement for mathematical model of the charging station in Matlab/Simulink. The function of model station is verified by a physical laboratory model. For options verification of the connection station to the distribution net is created simulation of voltage losses in Matlab/Simulink. The thesis shows four 24 hours’ scenarios that have been simulated. According to the assumptions of simulation, the technology of station and connecting component is suggested. Next is the designed energy and financial analysis of the project charging station until 2030.

Design and Realization of Mobile Photovoltaic Power Station
Lednický, Ján ; Morávek, Jan (referee) ; Baxant, Petr (advisor)
This diploma thesis entitled Design and realization of a mobile photovoltaic power plant is dividet into two parts. In the first, theoretical part one can learn about the state of representation of renewable energy sources in the field of electrical power engineering and about the structure of photovoltaic power station systems. The secont part of this thesis is focused on the own design and realization of the mobile photovoltaic power plant, on the selection of individual suitable components and ther dimensioning. In addition, a model of a mobile power plant has been created, on the basis of which the power plant was constructed. Finally, one can find a source code analysis of a power plant monitoring using a microcontroler

Safety of off-grid hybrid energy system operation
Orság, Štěpán ; Vrána, Michal (referee) ; Morávek, Jan (advisor)
The thesis deals with the safety of hybrid systems in island operation. The safety requirements for electrical installation with photovoltaic system and protection against electric shock are discussed. Hybrid battery systems have a lower short-circuit performance in islanded operation, compared to parallel operation with the distribution grid, so the thesis focuses on the specifics of islanded operation and the use of protections that are part of the PV inverter or electrical installation. The work includes the design of test procedures and measurements on selected inverters with subsequent evaluation and recommendation of further protection measures.
