Abstract

The usage of Photovoltaic (PV) energy system as a solar power plant has been growing rapidly in the world, because it is clean without emitting greenhouse gasses. The rapid development of power electronics technology has an impact in the development of PV system and the usage of non-linear household appliances that use inverter technology. In PV system, an inverter is used to convert direct current (DC) power from sunlight to alternating current (AC). Inverters usually have a switching rate higher than 1 kHz, which may cause waveform distortions and disturbances in AC power output, such as harmonics and disturbance in the frequency range 9-150 kHz. These disturbances may affect the performance of equipment, as well as neighbor equipment connected to the same network. This research is focused on analyzing the effect of current flowing in the non-linear household loads (induction cooker and compact fluorescent lamp) to the harmonics distortion (THDi, TDDi and harmonic voltage distortion) and disturbance in frequency 9-150 kHz on the Grid-connected Rooftop PV System by conducting laboratory measurement using a computer-based oscilloscope and power quality analyzer. The results show that the variation of current flowing in the equipment affects the harmonics distortion and disturbance in frequency 9-150 kHz.
