Abstract: In this paper, a low voltage smart grid is presented. The main characteristics and technologies for the construction of smart networks are presented. Two cases were investigated at 20kV and 21kV without and with a connected photovoltaic plant. A mathematical model was implemented, which was investigated using the NEPLAN software product. The simulation results are tabulated and compared. An assessment of energy efficiency, reliability and security of the produced electricity was made. The presented results are useful for determining optimal operating modes and also determining a specific node for connecting charging stations and energy storage elements to reduce peaks in load schedules.
