Using the Arduino module to manage the physical model of the MVE
Perout, Miroslav ; Vrána, Michal (referee) ; Radil, Lukáš (advisor)
This bachelor thesis is focused on acquaintance with the model of MVE and creation of a proposal of the structure of management on the basis of the obtained information. In the first step, the differences in the generators used are described and explained. Subsequently, according to the parameters of the measured system, individual measuring elements and modules are designed to send information to the selected microprocessor. In the last step, the issue of creating visualization software through the Processing environment is discussed.

Biomass for power plants in the off-grid operation
Roule, Jaroslav ; Radil, Lukáš (referee) ; Baxant, Petr (advisor)
The thesis discusses the use of biomass for electricity island operation. The first chapter explains the concept of biomass and its distribution. It also shows the potential and availability of biomass. The second chapter describes the transformation of biomass into a suitable fuel form. The third to fifth chapter describes the conversion of biomass as a fuel into electrical energy through combustion, Stirling and steam engine. In these chapters there are brought the following parameters and prices of these motors and single-phase and three-phase alternators that can be connected to these engines. Other chapters describe the production of electricity in line with consumption, where the cost per hour to run engines for the various types of fuel and price of the electricity produced in kilowatt hours is calculated. In the last chapter of the thesis there is described the possibility of accumulation of electrical energy.

Electricity balance in a typologically local system of an energy community with electricity production
Kaňa, Jiří ; Radil, Lukáš (referee) ; Drápela, Jiří (advisor)
The European trend of increasing the share of renewables and decentralizing energetics is leading to an enthusiastic debate over local energy communities. Mass support for this arrangement may seem to solve many of today's energetics problems, but at the same time we need to keep in mind the problematic aspects of the energy communities themselves. In particular, there is a need to resolve the economic and legal relations of the members of the community and to ensure the technical feasibility of such a transformation. This work summarizes the existing knowledge about the idea of energy communities, presents a summary of the most important information from a technical, economic and legal point of view in the context of the European and Czech environment and draws attention to the most pressing issues. Furthermore, the creation of a model of electricity consumption, photovoltaic production and metrics for measuring electricity with respect to the actual properties of the modeled systems is presented. In the final phase, a simulation of energy flows is performed on a model of an energy community with a specific topology with evaluation of the results.

Use of the railway traction elements for distribution system support
Dékány, Michal ; Radil, Lukáš (referee) ; Ptáček, Michal (advisor)
The bachelor thesis deals with the transition to a unified power supply system of the traction system of the Czech Republic. Describes the possibilities of using converters in various connections to improve the quality of electricity on the distributor side. The work presents current innovative solutions that use converters to support the distribution network by preventing the transmission of unwanted parameters from the traction network to the distribution network, such as higher harmonics, and also describes the possibilities of two-way power supply with their help.

Providing flexibility with detachable loads Procurement and commodity product prediction
Sykora, Jan ; Radil, Lukas ; Pilař, Martin
Flexibility is generally considered as the potential ofa facility (generation/consumption or storage) to actively changethe amount of its generation/consumption/accumulated energybased on price signals or direction. This control strategies ismanaged to correct deviations of the electricity grid or to ensurethat the purchase/sale of electricity is profitable for the flexibilityprovider. This paper presents a comparison of the control of heatpump consumption to provide consumption flexibility.

Basic principles of flexibility aggregation
Ošťádal, Martin ; Paar, Martin (referee) ; Radil, Lukáš (advisor)
This thesis deals with the basic principles of flexibility aggregation. In the beginning it introduces the history and present state in the field of regulation and prospects for the future. After defining the concepts associated with flexibility and aggregation, the necessary modifications for the functioning of flexibility aggregation are formulated. Next, foreign methods of energy regulation are mentioned, as well as possible obstacles to these new methods in the respective countries. The paper concludes with an analysis of data from Pecan Street Inc. to show the effect of flexibility on daily load profile and the similarity of power waveforms throughout the day for provided households.
