Abstract

Recently, the renewable energy power generation has been widely used in residential customer by installing PV-rooftop on grid system. The PV-rooftop system uses inverter, which may generate the disturbance in the frequency range of 9-150 kHz due to its frequency switching. On the other hand, many household appliances also use inverter technology in their operation that may also generate the disturbance in the frequency range of 9-150 kHz even when it is connected to the clean supply provided by the utility grid. Since the power supplied by PV-rooftop system may contain disturbance, it is important to explore the effect of PV-rooftop system to the disturbance generated by household appliances. The study investigates the disturbance profile due to the interaction between the disturbance generated by PV-rooftop system and the disturbance generated by the household appliances. The devices under test are PV-Rooftop system as the power supply and the induction cooker, inverter-based microwave, vacuum cleaner, CFL and LED lamp as the household appliances. The results of the measurement show that the PV-rooftop generates disturbance at frequency 16 kHz when operated individually. The disturbance generated by PV-rooftop system is generally reduced when the household appliance is connected. The disturbance reduction has different trend. Some appliances including induction cooker and inverter-based microwave reduce the disturbance significantly due to their low internal impedance at the frequency of 16 kHz that may filter the disturbance of PV-rooftop system.
