Abstract
To reduce emissions worldwide, decarbonization has also affected for power engineering and its conventional methods of power generation, distribution, and transmission. This fact affects not only the production of power and supply itself, but also other parts related to it, namely systems for the protection of electricity generation facilities and the location of faults in distribution networks and transmission systems. Is this new technology of renewable energy sources (RES) mastered enough to be able to replace traditional methods of energy generation reliably and safely? If we can answer the previous question, we could proceed to the next phase of putting these technologies into practice, considering the actual state of distribution networks and transmission systems. The aim of the article will be to evaluate the current state of systems and production sources of electricity in the Slovak Republic and to provide a better insight and suggestions for rebuilding current networks on a smart grid. The proposals will also include models of some RES in the Matlab/Simulink software.
Highlights
The construction or conversion of the current system into a smart grid will require a lot of effort for successful application, which will lead to uninterrupted power supply for all consumers, reduced transmission and distribution loss high penetration of renewable energy sources, cyber secured electrical network, large-scale power storage, creation of new opportunities for the electricity market, and active involvement of costumers in the management process [1]
Research shows microgrid systems will be a key part of building smart grids, and this major part provides solutions for powering remote communities and industrial facilities and military bases that are usually connected to the grid so that they can disconnect and operate independently

Summary
The construction or conversion of the current system into a smart grid will require a lot of effort for successful application, which will lead to uninterrupted power supply for all consumers, reduced transmission and distribution loss high penetration of renewable energy sources, cyber secured electrical network, large-scale power storage, creation of new opportunities for the electricity market, and active involvement of costumers in the management process [1]. We use only one direction, from production to consumption, but in smart grid, this fact changes into a twoway flow of energy, with the consumers themselves participating in the production [2]. These are the main advantages and goals of a smart grid and for such a network to work, it is first necessary to master a similar management on a smaller scale in a microgrid.
