摘要
Systems, methods, and devices relating to the controlling of a grid-connected inverter. A grid connected inverter is controlled by a proportional-resonant controller which tracks the grid current. To adjust for changes in grid conditions, an update block dynamically and continuously adjusts coefficients used by the controller to ensure high gains provided by the controller at the grid frequency. A harmonic compensator is also provided to ensure that high loop gains at harmonic frequencies of the grid frequency are also provided for. To also adjust for changing grid conditions, a second update block also continuously adjusts the coefficients used by the harmonic compensator.
