  "textContent": "The present disclosure provides an islanding detection method for an inverter and a corresponding apparatus. The islanding detection method includes: step A obtaining a parameter of an output voltage of a three-phase AC system and a steady-state value corresponding to the parameter within a period of time; step A obtaining a disturbance signal based on the parameter and the steady-state value; step A superimposing the disturbance signal on at least one reference value of a droop control; and step A detecting the parameter added with the disturbance signal, and determining that island occurs in response to the parameter greater than an upper limit or less than a lower limit.",
