Popis: Currently, a transition is underway from traditional power supply networks to smart grids that provide power to consumers, redistribute and improve the quality of electricity, reliability and efficiency. One of the directions for the development of the concept of smart grids can be implemented on the basis of the use of solid-state transformers in power supply systems. The article presents the results of modeling the modes of the power supply system with asymmetry of phase voltages; the effect of solid-state transformers on power quality was investigated. The studies were carried out using Simulink. The coefficients of the voltage unbalance in the negative sequence and the coefficients of the voltage unbalance in the zero sequence are determined. As a result of numerical modeling, it was found that the use of solid-state transformers can improve the quality of electricity and ensure reliable integration into the power supply system of distributed generation installations.
