Possibilities of using a photovoltaic system in a family home
Herník, Martin ; Linda, Jakub (referee) ; Toman, Filip (advisor)
This bachelor thesis deals with the design of a photovoltaic power plant that will meet the needs and conditions of a specific family house. The design includes photovoltaic options such as battery and non-battery system solutions. In this work, the selection of appropriate components was made, where the emphasis was on achieving optimum system performance and minimizing costs while maintaining given efficiency and reliability. Finally, the economic evaluation of the two solutions in terms of cost and paybacks is assessed. The final design is proposed in the light of the current energy price situation and the continuous forward movement of PV technology.

Design of photovoltaic system configurations for a family house
Prágr, Vojtěch ; Zlevorová, Tereza (referee) ; Toman, Filip (advisor)
This bachelor thesis focuses on the design of a photovoltaic system for a specific single-family house. During the draft, the house’s energy consumption was processed, and based on this data, three different system configurations were proposed. Two of these configurations have different power outputs and storage capacities, while the third was designed to operate the water heater that the house contains. In the thesis, the proposed systems were evaluated from an economic perspective, considering the initial costs of individual systems, as well as the operation and service expanses. Finally, according to these aspects, the ROIs of individual configurations were determined.

Efficient use of renewable energy sources in a residential building
Burčo, Matúš ; Paluřík, Pavel (referee) ; Jablončík, Lukáš (advisor)
The thesis focuses on the design and implementation of an optimization algorithm for an energy management system in apartment buildings. The thesis analyzes current technological solutions for smart home energy management, including open-source and commercial systems. It further considers the use of containerization technologies for the implementation of the algorithm in practice. The second chapter focuses on renewable energy sources such as solar, wind and hydro power and discusses methods for their efficient integration into energy systems. The third chapter describes specific system elements, such as photovoltaic panels and battery storage, in the context of a residential building. The fourth chapter describes the development of the optimization algorithm, its testing and integration with data collection and visualization platforms. The aim of the thesis is to show how the system can be used to make efficient use of the available energy resources and thus reduce the energy costs of the building.

Battery energy storage sizing optimization in industrial buildings with renewables
Prečuch, Martin ; Vrána, Michal (referee) ; Vojtek, Martin (advisor)
The aim of this work was to create an application, a software tool, which will allow to optimally choose the size of the battery storage, from an economic and technical point of view, using the calculation of energy and power balances. These calculations are based on input data for a defined period, object onsumption, battery storage parameters and photovoltaic power plant. In the theoretical part of the work, research was conducted to find suitable storage devices for industrial facilities and explore their potential applications. The third chapter covers the algorithmization and development of an application focused on peak shaving and reducing the reserved capacity of an industrial facility through battery storage. The chapter describes in detail the necessary input data for simulation, application development, and individual parts of the program are described using flow diagrams. Following this, the creation of the graphical user interface of the application and the economic analysis are detailed. The fourth chapter presents a case study with two scenarios. Based on the case study, the functionality of the application was verified, confirmed, and demonstrated.

Analyses of properties of photovoltaic inverters
Melichařík, Martin ; Vyroubal, Petr (referee) ; Vaněk, Jiří (advisor)
The thesis deals with photovoltaic systems with a focus on photovoltaic inverters. Solinteg, a company with a growing clientele, needs to set up a workstation to analyse PV inverters and systems at their branch in Brno for the European market. There are different types of system using different inverters and so the analysis for a particular system or inverter may be different. For a thorough analysis of these systems, special laboratory equipment is required, such as special power supplies and loads to simulate fault or operating conditions, complemented by measurement tools such as a power analyzer.

Infrastructure for electromobility
Smutková, Karolína ; Böhm, Michael (referee) ; Štětina, Josef (advisor)
This thesis deals with the issue of charging electric vehicles, including a number of sub-questions. It provides an overview of current charging stations, connectors, communication between vehicle and charger during charging and of the resulting price for charging. It also takes into account the need for large amounts of energy mostly from renewable sources, coupled with battery storage facilities. The last point is a comparison of current electric vehicles mainly by battery capacity, price and range. The whole thesis is primarily related to the territory of the Czech Republic.

Design of PV plant with accumulation for commercial building
Jörka, Lukáš ; Morávek, Jan (referee) ; Mastný, Petr (advisor)
This Master´s Thesis deals with the design of photovoltaic power plant with accumulation for commercial building in the city of Holešov. The first part of the thesis describes the requirements for connection and operation of power supplies with inverters according to Annex 4 of the PPDS and the European Commission directive RfG. The second part of the work focuses on the theory of photovoltaic systems, while their basic concepts are introduced, the individual components of photovoltaic systems are described, and eventually, the issue of inverters dimensioning is discussed in more depth. In the practical part of this thesis, the design of photovoltaic power plant with accumulation using the PVSOL program is performed. Within the design, components for PV plant with accumulation are selected, the project documentation of PV plant for building permit is prepared and the energy-economic analysis of the proposed solution is performed.

Energy supply of the ski resort
Turčina, Lukáš ; Skála, Zdeněk (referee) ; Pospíšil, Jiří (advisor)
The environmental targets of the European Union Member States are to achieve carbon neutrality in the next few years by producing green energy. To offset the impact of climate change causalities, it is crucial to increase the share of renewable energy resources as well as to reduce the dependence on fossil fuel imports. The main focus of the thesis is to increase energy sourced from alternative resources in ski resorts. Furthermore, a specific design of a wind power plant located directly in the ski resort together with the storage of the remaining energy is introduced to achieve the thesis’ objective. To select a suitable wind turbine, there is a need to choose a proper construction site that should dispose of stability and good-quality wind conditions. The performed analysis concentrates on the wind speed and frequency on the identified site. As a result, the performance of the selected wind turbine can be calculated. Moreover, given the turbine power and wind frequency, the amount of energy produced can be calculated. The potential electricity production is then compared with the ski resort’s consumption. The findings suggest that with suitable wind conditions and proper planning of energy production and storage, it is possible to cover a significant amount of the resort’s consumption. However, the model is dependent on the speed and stability of the wind, which may be highly volatile over time. Nevertheless, even such small steps can be crucial to achieving the set goals and can indicate the direction in which society will move towards.
