Design, Creation and Implementation of Software Applications in the Corporate Environment
Kulda, Lukáš ; Koch, Miloš (referee) ; Novák, Lukáš (advisor)
This diploma thesis deals with the design and implementation of a web application for inventory management in an agricultural company. This work is an application that aims to improve the shortcomings of the company in the field of inventory management. The first important chapter is the theoretical basis on which the work is based. The next main chapter is the analysis of the current situation of the company which justifies the needed change. This is immediately followed by a chapter describing the introduced change, the implementation of the application and its benefits for the company.

Control and monitoring of a distributed energy generation systems based on renewable sources with storage system
Smugala, Ondrej ; Paar, Martin (referee) ; Vrána, Michal (advisor)
The diploma thesis is dealing with possible approaches to control distributed energy resources and storage systems. One of these approaches is a virtual power plant and its concept is described in the first part of the thesis. The virtual power plant is a controlled system of distributed energy resources, storage systems and controllable loads interconnected via communication network, that can act as a conventional power plant. The theoretical part contains a survey of control system's topologies, a brief summary of available communication infrastructures and standards. The second part of the thesis is focused on the description of operation and control of hybrid system that represents an inseparable component of virtual power plant. A Matlab Simulink model was created for this purpose. A simulation of hybrid inverter's step response is realised to test the operation of the hybrid system and it is compared with the real measurements in the laboratory. A comparison of control approaches of hybrid system implemented on the basis of measurements is also included in this thesis and was published in the scientific paper attached in the appendix.

Wind power generation and energy accumulation possibilities
Krbal, Michal ; Mastný, Petr (referee) ; Drápela, Jiří (advisor)
The goal of this bachelor’s thesis is to inform about conditions of running and the character of running of the wind power plants and about the suitable storage systems for the possibilities of time invariableness of power supply. For these reasons is immediately in the first chapter of the thesis described state of using wind power plants in The Czech republic and other countries in Europe which produce electric power. Description of individual functional parts is important mainly from the point of electrician conversion of kinetic energy of wind to electric energy with help of the electric power generator with the highest efficiency and without need for maintenance. It is necessary to know those functional parts of the power wind to be able to design appropriate storage system. The output electric power is very variable at time, mainly output voltage, because wind energy is variable too. The characteristics of the wind power plants as output voltage, frequency and their switching graded at time have to in accordance with requirements of the electricity supply systems not to disturb the stability or even collapse of the electricity supply system which would lead to serious economic consequences. These predicaments can be prevented with precise meteorological forecast or by using the acceptable storage system with small acquisition and operating costs, requirements to safeness and long service life, low weight and high efficiency of conversion of energy. The storage systems are classified into centralized and decentralizing systems with requirements to dynamic running and running time. To fulfil these conditions it is essential to choose acceptable and accessible locations with year lasting qualities of wind, which are being checked in advance using measurement and mathematical calculations.
