要約(日本語): Distributed Generation (DG) is expected to improve distribution system reliability as its backup generation. However, DG contribution in fault current may cause the loss of the existing protection coordination. This problem can drastically deteriorate the system reliability, and it is more serious and complicated when there are several DG sources in the system. The model of composite DG fault current is proposed to find the threshold beyond which existing protection coordination is lost. The issues of tie line and on-site DG are also integrated into this study. Numerical results are conducted in the distribution reliability test system RBTS Bus 2.
