Modernization of the electrical grid has led to progress in the production, transmission and distribution of electricity. The "smart grid" concept aims to optimize energy efficiency, increase reliability and optimize the integration of electricity production from renewable sources. Smart grid features intelligently interconnected grid elements. Thesis discusses the area of smart networks and potential implementation within the framework of a smart network using the example of the substation Duboka 10(20)/0.4 kV. The basic principles of the smart grid and its advantages will be discussed in this thesis. Power Logic PM5310 and logic controller M241 have the task of collecting measurements with continuous communication with the central monitoring and control center. The potential benefits and complexity of smart grid implementation will be emphasized along with procedures for upgrading the energy infrastructure for remote control purposes.
