  • islanding detection;
  • reliability of islanding detection methods - represented by nondetection zone (NDZ);
  • point of common coupling (PCC);
  • islanding detection methods and three main approaches;
  • grid-resident methods, and communication - grid and PV inverters, different from other inverter-resident techniques;
  • external switched capacitor (ESC) detection - external capacitor, in parallel with grid, zero-crossing delay;
  • passive methods, based on monitoring grid parameters - changing during islanding;
  • passive anti-islanding methods;
  • active frequency drift - with positive feedback (AFDPF);
  • HI, used as an islanding detection method - and ENS requirements
