Effect of Connected Non-Linear Household Appliances on the Disturbance at Frequency Range of 9-150 kHz in the On- Grid Photovoltaic System

Nowadays, the usage of power electronic circuit which is called inverter is increasing especially in household appliances. This inverter technology is the technology that can convert alternating current (AC) to direct current (DC), and this technology may produce disturbance at frequency range 9-150 kHz. In the residential area, a house can be built one of on-grid photovoltaic (PV) system, and the usage of household appliances inside the house system can be connected together at same time and operated simultaneously. This research is focused on investigating the effect of connected household appliances, such as induction cooker. The result shows that the connected two types of induction cooker in same system may either increase or decrease the disturbance value in the system. The connected appliances affect the disturbance through by the power consumption.
