Návrh modelu smart grid.

Abstract

The aim of this bachelor thesis is to design and create a physical model of smart electricity grid. This model is designed to visually show the energy flow in the lines of distribution grid which is equipped with telecommunication and data networks for advanced network management. A network contains of all the elements which are anticipated in theory of smart grids. In the model there we can find a distributed generation, a local micro grid which is formed from a residential area, a settlement representing the medium-volume consumer and a factory representing high-volume consumption. Furthermore, on the model we can find the central battery serving for power balance management and the connection to the superior power electricity grid. The visualization of the model is performed so that the model clearly provides the understanding of the smart grid model. It is possible to use the model as a learning material for initial familiarization with the operation and the topology of the smart grid. The model is equipped with various visual elements: there are LEDs and small DC motors. Everything is controlled by the control board directly created for the managing this model. The microprocessor of the control board is programmed so that the model works in several modes with various value of electric power generated by the distributed generators. The text part of the bachelor thesis is divided into two parts. The first part contains theoretical analysis of the smart grids. The second part deals with the physical model: there is the model description, the description of its functional modes, schematics of circuit boards which were used in the model, details pictures of the model individual parts and drawings created during the design phase of the model creation process.
