PQ events classification and detection - A survey

This paper carries out a comprehensive review of various techniques used in the recent years in PQ event classification. Within this context, artificial intelligence and optimization techniques as well as their fusion have been reviewed in the field of PQ. The important techniques used in past are also provided in tabular form. Although this review cannot be collectively exhaustive, it may be considered as a valuable guide for researchers who are interested in the domain of PQ and wish to explore the opportunities offered by these techniques for further improvement in the same field. It is also analysed that still more research is to be done for online analysis of PQ events.
