Abstract

Tests and a study for preventing the islanding phenomenon have been conducted. Several islanding methods applicable to both PV power systems and utility grids were designed, and the validity of those methods is being evaluated. As a result, the validity of the harmonic voltage monitoring method was demonstrated. The power output variation method is also likely to be applicable. As for a prevention method applied to a utility grid, the validity of the method of unbalancing reactive power by connecting a capacitor load to the grid on islanding was confirmed. Results of demonstration tests for prevention of the islanding phenomenon are described
