Different configurations of microgrids and power converters
Abstract
This thesis proposes a two-phase microgrid system with voltages in quadrature. The two-phase microgrid system presents the following advantages: 1) constant power through the power line at balanced condition; 2) two voltages available by using a three-wire system; 3) optimized voltage utilization compared to a three-phase system; and 4) a direct connection of both symmetrical two-phase and single-phase machines. Power analysis and symmetrical components of this kind of microgrid have also been studied through this thesis. Besides the two-phase microgrid system, the hybrid DC/AC microgrid has been analyzed. Both hybrid DC/AC and two-phase microgrid need power interfaces such as power converters to be connected to the grid. Also two different types of power converters have been proposed and studied during this thesis.
