Keywords:

  • grid synchronization - in single-phase power converters;
  • electrical grids, complex and dynamic systems - affected by multiple eventualities, as continuous connection and disconnection of loads, disturbances and resonances;
  • grid variable monitoring, task implemented in power converter - interfacing renewable energy sources to grid;
  • grid synchronization techniques - for single-phase systems;
  • Fourier series, discrete Fourier transform (DFT) - and recursive discrete Fourier transform (RDFT);
  • grid synchronization - using a phase-locked loop;
  • phase-locked loop (PLL), a closed-loop system - internal oscillator control, keeping time of external periodical signal using feedback loop;
