1. The grid-connected inverter is an important energy conversion device in renewable energy power generation.
2. The proposed control strategy reshapes the q-axis impedance of the inverter into a positive resistance in the low-frequency band, eliminating the negative effect introduced by the PLL and GVF.
3. The conclusions are verified by experimental results.
