Residential customers are one of the main electrical energy consumers and residential demand response applications will provide significant benefits to both consumers and utility companies under smart grid concept. A simple way of implementing residential demand response algorithms is to use smart plugs to control household appliances. Although on/off control of appliances is commonly used method in residential demand response applications, voltage controlled operation of appliances can also be used through a thyristor based smart plug. However, such an operation will introduce harmonics into the system due to ac voltage chopping. In this study, line current harmonics of a residential house, due to voltage controlled operation of appliances, is analyzed using PSIM software. Case studies are completed and it is concluded that the voltage controlled operation of appliances is a viable solution while staying within the current harmonics limits specified in IEEE Std. 519-2014.
