Fractional‐Order Impedance Reshaping and Integral Finite‐Time Control for LCL Grid‐Connected Inverters in Weak Grids

ABSTRACT Under extremely weak grids (short‐circuit ratio, SCR < 2), LCL grid‐connected inverters suffer severe wideband resonance and degraded transient performance due to voltage feedforward phase lag and phase‐locked loop (PLL) negative impedance. To circumvent the trade‐off be...
