Islanding detection method based on a Thevenin‐like model

open access: yesIET Generation, Transmission & Distribution, 2015
Reliable detection of islanded operation is essential in distribution systems with large penetration of the distributed generation. Commonly‐used protections present performance limitations in terms of sensitivity and stability. To overcome such limitations, this study proposes to enrich classical protections by adding a passive islanding detector ...

A Novel Decomposition for Control of DC Circuits and Grid Models with Heterogeneous Energy Sources [PDF]

open access: yes, 2017
The way in which electric power depends on the topology of circuits with mixed voltage and current sources is examined. The power flowing in any steady-state DC circuit is shown to depend on a minimal set of key variables called fundamental node voltages
