A microgrid (MG) is supposed to operate in both grid-tied mode and islanded mode, smooth transition between which is critical for its reliability. Past efforts have shown that proper control of converter-interfaced distributed generation (DG) units can help maintain stability of MG against islanding. However, it remains unknown as how to quantify and when to initialize such controls. This paper presents...
The interaction between synchronous generator and islanding detection of power conditioning system (PCS) for distributed generation, especially bases on positive frequency feedback by reactive power injection, is focused in this paper. When PCS using frequency-feedback islanding detection system are installed to power system intensively, PCSs are afraid to deteriorate the frequency stability. This...
