Document Generation System for Energy Optimization
Hrabě, David ; Zaklová, Kristýna (referee) ; Hynek, Jiří (advisor)
The goal of the thesis was the design and implementation of software for the company Optimal-Energy.cz, a.s., which automatically proposes measures for optimizing the resource consumption of buildings, especially the installation of photovoltaic systems and heat pumps. Based on the calculations, it generates documents that inform the customer about the proposed optimizations and contain the necessary contracts for performing the installation. The approaches to document creation and the possibilities of its automation have been analyzed. The original energy optimization calculations have been simplified and unified to operate on a common model based on the performed analysis. The solution was then implemented in the .NET environment using the F# and C# programming languages.

Evaluation of the development potential of the production restriction plan for PV and Wind power plant
Petryšak, Vladimír ; Pistora, Martin (referee) ; Bátora, Branislav (advisor)
This thesis deals with evaluation of the development potential of the Production restriction plan for PV and Wind power plant. The aim of the thesis is to analyze the possibilities of integrating various types of renewable energy sources into this plan, which aims to regulate electricity production from these sources in extraordinary situations. The thesis describes current technical and legislative possibilities for curtailing renewable sources used in the Production restriction plan, addresses the obligations of electricity producers, and proposes recommendations for further development of the Production restiction plan for renewable energy sources (RES).

Townhouse
Palata, Jiří ; Dokoupilová Pazderková, Kateřina (referee) ; Ležatka, Lukáš (advisor)
The subject of the diploma thesis is the design of a set of town houses within the Veveří, Pekárenská, Kounicova and Závodní blocks in Brno. The town house represents a historical archetype that represents the ideal functional composition of the building within the compact structure of the development in the wider center of Brno. The polyfunctionality of individual houses consists of a vertical functional division, where the ground floor is usually home to commercial units intended for catering, trade, administration or small production. Urban blocks, by their closure, firmly define the boundary between private and public. Public space is fairly dedicated to all. The non-public inner block is dedicated only to residents, which provides a rare added value with its functional content from recreational sports, relaxation, gardening. Some apartments are also oriented towards the inner block, which have direct contact between the interior and the exterior. On the higher floors, access to the exterior is ensured by means of loggias, balconies and terraces of stepped floors. Part of the inner block is dedicated to a single-storey supermarket, the capacity of which follows on from the existing operation. The roof of the supermarket is a connected part of the terrain of the inner block. On the roof there is a recreational multifunctional playground, an active sports area, a terrace connected to the community hall and a community sauna. All sections have access to a shared courtyard for residents. The underground parking is situated on two floors, separated from the parking for residents and visitors to the supermarket and other commercial units. The character and spatial solution of the objects is based on knowledge of the place and the surrounding objects, which are located in the city's heritage zone on the near border of the Brno city heritage reserve. The building thus brings a new architectural layer to the place with respect for its surroundings. The building is divided by urban-architectural details, such as stepped floors, accented corners, risality, gabled roof gables, vertical material solution of the facade or the same rectangular format of vertical window openings. However, the architectural solution inspired by history is dressed in a contemporary coat, which ensures the careful use of energy, rainwater management, the support of biodiversity and, with its positive approach to the human scale, the support of social sustainability. Vegetation areas for rainwater management are located not only on roofs, but also on facades, specifically on railings, which are the subject of a separate architectural detail solution. In addition to individual town houses, the proposal also includes the creation of the structure and character of public spaces. In particular, the character of the city street Veveří is strengthened, the new Závodní street is created and the character of the existing service streets is adjusted, in which the pedestrian is favored over the driver, and adequate traffic calming solutions were chosen with the aim of supporting mobility by public transport. Professor Chudoba's memorial tree is the centerpiece of the new important public space, with its parameters of a patch. A majestic tree closes the interior of this space and creates an ideal environment for meetings with the possibility of a longer stay thanks to the situated catering facilities.

Integration of Grid-Forming and Grid-Following inverters into the grid
Sýkora, Jan ; Klusáček, Jan (referee) ; Radil, Lukáš (advisor)
The thesis deals with the integration of Grid-Forming and Grid-Following generation plants into the grid. The key parts of this thesis are the assessment of the current state and development of the resource base of the Czech Republic, a critical study of the limiting share of resources lacking natural inertia for maintaining stable and safe operation of the grid and the definition of the nature of inverter resources in "Grid-Forming" and "Grid-Following" modes. The main contribution of the work is the development of models of "Grid-Forming" and "Grid-Following" inverters in order to verify the capability of operation in grid-on mode and their response to disturbances in the system.

The development of energetics in the Czech Republic during the following years
Musil, Miloš ; Kracík, Petr (referee) ; Toman, Filip (advisor)
This thesis analyses the current Czech energy sector. It describes its current state and outlines possible scenarios of its development in future years in the context of the energy transformation. The thesis seeks to analyse the current situation of the energy sector in the country, assess its strengths and weaknesses and identify opportunities and threats for future development. The thesis describes the different parts of the Czech energy sector, such as the electricity, gas, heating and oil industries, including production sources, consumption and emissions. Most emphasis is given to the electricity sector. The capacities and potentials of the different sectors are analysed alongside the possible future scenarios outlined. Part of the thesis is also focused on describing and explaining the composition and construction of electricity and gas prices in the Czech Republic. Emphasis is also placed on placing the Czech energy sector in the broader context of the energy sectors of European countries and includes various scenarios for the development of the electricity sector in Europe. In the context of the current geopolitical situation in Europe and the modernisation and transformation of this sector, it is necessary to build new energy sources.

Wind power plant
Šponiarová, Petra ; Prokop, Aleš (referee) ; Řehák, Kamil (advisor)
The electricity production from renewable sources is a very current topic. It also includes the electricity made by wind power plants, which the bachelor’s thesis concentrates on. An extensive research study was conducted to provide an overview of wind turbine types. Concerning wind power plants, apart from their visual impact, noise and vibration connected to their operating is an often discussed issue. The construction of a wind turbine stands for the most important role in reducing such unwanted effects. Technical experiments following specific standards and recommendations are performed to assess the impact of wind turbines-emitted noise and vibration on humans. In order to assess noise and vibration of a wind turbine a technical experiment is proposed, which uses different approaches to determine the critical components. The selection of a suitable measuring equipment and the choice of location for its subsequent use are important parts of the design. At last, the use of wind power plants is critically reviewed.
