The development of a scaled-down simulator for distribution grids and its application for verifying interference behavior among a number of module integrated converters (MIC)

Description

Islanding is one of the serious problems in an electric power system connected with dispersed power sources. To secure the power system from islanding, it is quite important to verify the ability of islanding detection for the individual power sources in advance. The authors have been developing a scaled-down, simulated distribution network including a distribution substation, 6.6 kV distribution line, pole transformers, low-voltage lines, customer loads and a number of PV systems. This paper describes the development of the scaled-down simulator and the experimental results about the interference phenomena among multiple module integrated converters (MIC).
