Smart grid integration of micro hybrid power system using 6-switched 3-level inverter

Abstract

A hybrid power system modeled in Matlab/Simulink environment is presented in this study. This model includes a hybrid system consisting of wind and solar panels and it is connected to the smart grid through a 6-switched 3-level inverter. A 6-switched 3-level inverter is preferred in this study as an inverter due to its success in minimizing the harmonics. The signals required for the operation of the semiconductor switches within the inverter are obtained by the space-vector pulse width modulation technique. The system fed the receivers by generating electricity energy and sent the generated excess energy to the grid (grid) on favorable conditions, that is, when wind and/or sun are sufficient for energy production. The receivers are fed by the grid on unfavorable conditions. By means of analyzing the performance of the system, it is determined that the system is stable.
