Power quality subcommittee of IEEEPES has carried out a series of working meetings in 2015 IEEEPES Joint Technical Committee Meeting. The subcommittee has developed and revised several core standards on power quality. New power quality problems and demands in the smart grid draw great attention from every project group. Rapid change of voltage and arc detection have been involved into IEEE Std 1159—2009. Power quality data interchange format has been extended correspondingly. The effects of new energy to power quality
the evaluation and testing technology of energy saving devices are becoming new research fields. The technical report ‘power quality in the future grid’ and the feasibility of integrating power quality monitoring function into revenue meters have been discussed.
