PV power plant project - category A1/A2
Pacalaj, Timotej ; Drápela, Jiří (referee) ; Morávek, Jan (advisor)
This thesis deals with the design of a category A1/A2 photovoltaic system for a specific building. The aim was to meet the requirements of the investor and the energy needs of the building. The thesis includes a research of PV connection requirements (PPDS-4, RfG), a review of available technologies and components, and system design using PVSOL software. The work also includes the production of project-level documentation for implementation, including a technical report, a single-pole schematic and a situation drawing. In addition to the technical aspects, an economic evaluation of the project is carried out in the thesis, providing the investor with an overview of the return on investment and financial efficiency of the PV plant. As a result, a comprehensive proposal for the implementation of a category A1/A2 PV plant is presented, taking into account both technical and economic aspects.

Integrated Measurement System for In-Field Compliance Testing
Chvalová, Aneta ; Morávek, Jan (referee) ; Dvořáček, Jiří (advisor)
As the number of renewable energy sources has increased, new installations have been subject to new requirements for their control, whether autonomous (responding to conditions at the point of connection) or dispatchable. An important step for the commissioning of photovoltaic (PV) plants is to perform compliance testing, which is sometimes only appropriate or necessary to perform in the field on a complete installed plant. The measurements are used to obtain a set of data which is then used to issue a certificate of correct operation (i.e. compliance with requirements). The main output is a measurement system assembled into a portable case that can be easily transported to the PV installation site and simply connect the measurement analyzer to both the AC at low voltage level (for recording voltage, current, power, frequency) and DC (for recording binary commands and signaling). Also included is elaborate documentation of the case itself.

Photovoltaic system in cooperation with a charging station for electric vehicles
Zerzán, Jan ; Morávek, Jan (referee) ; Mastný, Petr (advisor)
The thesis deals with the design of photovoltaic power plant with accumulation and charging station for an electric car for a family house located in the Pardubice region. First, the individual parts of photovoltaic system are theoretically described and then the requiments for connection to distribution system are described. At the end of the theoretical part, the subsidy program is described. The practical part consists of the design of the photovoltaic system and subsequently it’s project documentation. Another topic in the thesis is the simulation and control of the energy flows of the designed PV plant with batteries and EV charger in Matlab. Towards the end of the thesis an economic balance sheet is created.

Design of system wiring and energy management for a family house with PV
Honkyš, Jan ; Morávek, Jan (referee) ; Bátora, Branislav (advisor)
This work deals with the design of system wiring and energy management for a family house with a photovoltaic power plant. The current state of the house's electrical installation does not meet current standards. The theoretical introduction of the work deals with the description of system electrical installation and building management systems. Another part of the work deals with the design of photovoltaic power plant on the roof of the house. The design was economically evaluated, including subsidy programs. Home control system has been designed to effectively manage the home's operations and minimize operating costs. Energy management was designed, which will effectively use the produced photovoltaic power. Project documentation was prepared, which will be used for future implementation.

Project documentation of photovoltaic power plant category B1
Rehák, Jan ; Mastný, Petr (referee) ; Morávek, Jan (advisor)
This thesis focuses on project documentation for a photovoltaic power plant. Requirements for parallel connection of power plants with installed power from 100 kW to 1 MW to the distribution grid are studied. Next, research has been conducted on individual components and options for local and dispatch control of photovoltaic power plants. The practical part of the thesis focuses on the creation of project documentation for an embedded photovoltaic power plant located in the buildings of FEKT Brno University of Technology. The final part of the thesis includes an economic evaluation of the project.

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.
