Admittance Modeling and Stability Analysis of Grid-Connected Inverter With LADRC-PLL [PDF]

IEEE Transactions on Industrial Electronics, 2020
It tends to cause system oscillation when the inverter with a phase-locked loop based on proportional integral controller (PI-PLL) is connected to the weak grid. To improve the oscillation suppression ability of the grid-connected inverter, a linear active disturbance rejection controller is applied to PLL (LADRC-PLL).
