Modeling and Simulation of a Three-Phase Grid-Connected System Using PSCAD

Modeling of a three-phase inverter connected to the power grid and load using the power system computer-aided design (PSCAD) software was established in the study. When the three-phase inverter is connected to the power grid, the three-phase AC signal can be converted to the DC signal using the direct quadrature transformation to achieve the power and current controls. The simulation results confirmed that the PSCAD model could be implemented in the power-sharing performance between the load and the power grid.
