Conference
The history of the IEEE International Conference on Harmonics and Quality of Power (ICHQP) can be traced back to 1984, when the IEEE International Conference on Harmonics in Power Systems (ICHPS) was established to facilitate the exchange of ideas amongst researchers working on power system harmonics. The conference series was renamed in 1996 as the IEEE ICHQP when its scope was expanded to include all aspects of power quality.
Since its foundation, the conference has been held once every two years at locations traversing the globe, providing a truly international forum and fostering the development of the power quality community.
Further details of the story of the IEEE ICHQP conference can be found in the summary presentation “A History of ICHQP” prepared by the conference founder, Alex Emanuel, for the 15th edition of the conference in Hong Kong. The full list of past editions is available in Past Editions.
