Robustness Improvement of Single-Phase Inverters Under Weak Grid Cases by Adding Grid Current Feedforward in Delay-Based Phase-Locked Loop
For inverters, a phase-locked loop (PLL) is usually needed for the grid synchronization. Typically, for the single-phase inverters, the orthogonal-signal-generators based PLLs (e.g., delay-based PLL) can be used. However, if the grid at the point of common coupling (PCC) exhibits a large grid impeda...
