Abstract

Islanding detection methods have been proposed for inverter based distributed generation (DG) with grid connected capability only. Micro-grids are composed of DGs that are capable of operating in two modes: grid connected and islanded. This paper introduces and proposes the concept of micro-grid transition detection where the status of the micro-grid is detected based on adaptively modifying the droop slope. The droop coefficient is chosen such that the micro-grid is stable while grid connected, but unstable as soon as an islanded micro-grid operation is initiated. The droop coefficient is adaptively modified, once the micro-grid shifts from grid connected to islanded operation, to stabilize the micro-grid for the islanded mode of operation. The proposed micro-grid transition detection method is tested on a micro-grid equipped with inverter based DGs controlled using the droop approach.
