Abstract
This paper introduces a methodology to forecast voltage total harmonic distortion (THD) at low voltage busbars
of residential distribution feeders based on the data provided by a limited number of smart meters. The meth-
odology provides relevant power quality indices to system operators using only the existing monitoring infra-
structure required for demand response operation. Different algorithms for voltage THD forecasting are
implemented, including artificial neural networks, and their performance is tested and compared. The necessary
coverage of smart meters for the acceptable accuracy of the estimated THD is also established. The estimation
algorithms are validated considering probabilistic demand load model developed based on typical harmonic
injections of household devices obtained from measurements and using a typical European low voltage test-
feeder with 471 residential consumers.
