Classical view of power system is characterized by a unidirectional power flow from
centralized generation to consumers. Power system deregulation gave impetus to a
modern view by introducing distributed generations (DGs) into distribution systems,
leading to a bi-directional power flow. Several benefits of embedding DGs into
distribution systems, such as increased reliability and reduced system losses, can be
achieved. However, when a zone of the distribution system remains energized after being
disconnected from the grid, DGs become islanded and early detection is needed to avoid
several operational issues.
In response to this call, a wavelet-based approach that uses the mean voltage index is
proposed in this work to detect islanding operation in distribution systems embedding
DGs. The proposed approach has been tested in several islanding and non-islanding
scenarios using IEEE 13-bus distribution system. The results have shown the
effectiveness of the proposed approach compared to other islanding approaches
previously published in the literature. / UOIT
