A Synchronization Shift Phase-Locked Loop Strategy for Three-Phase Grid-Tied Inverters Under Unbalanced Grid Voltage Scenarios

IEEE Access, 2023
The phase-locked loop (PLL) is one of the most commonly used approaches for the inverter to achieve grid-connected operation. However, when unbalanced grid voltages occur, the double-line frequency oscillation exists in the system.

Direct power control of voltage source inverters with unbalanced grid voltages

IET Power Electronics, 2008
A new approach of direct power control (DPC) of a voltage source inverter for achieving symmetrical grid currents under unbalanced grid voltage conditions is presented. In these situations, negative sequence components appear on the grid voltage vector, leading to distorted currents if the power is maintained constant. Nevertheless, sinusoidal balanced
