Impact of DG interface control on islanding detection

Abstract

Within recent years, many islanding detection methods have been proposed as a result of the high penetration of the distributed generation (DG) in the distribution system. With the increasing reliance of the distribution system on DGs and knowing that DGs can provide many favorable aspects, other than providing active power, new interface controls have been proposed recently. Most of the current proposed DG interface controls are designed to supply both active and reactive power to provide voltage support and power factor improvement and this in turn could have an impact on islanding detection. Islanding detection methods are designed for DGs operating at unity power factor. The main goal of this paper is to implement some of the interface controls that allow the DG to operate efficiently and at the same time examine their effect on islanding detection.
