Abstract

In the future active network management and protectionsolutions have to enable utilization of intended islandoperation as well as active control and utilizationflexibilities during normal and islanded operation ofgrid interactive microgrids. In this paper, combinedislanding detection schemes for both MV and LVnetwork connected distributed generation units duringnormal grid-connected operation are studied.Utilization of active network management functionalityat MV level enables to control the reactive powerunbalance continuously in order to ensure reliableislanding detection without non-detection zone.Combined scheme also prevents maloperations due toother disturbances.
