The Impact of Embedded Generation Due to Harmonic Performance

Abstract

The paper investigates the most suitable location of inverter connection installed into the distribution line feeder. Thus, it can reduce losses, control voltages as well as the protection system. Besides, it is more focused on mitigated a whack-a-mole phenomenon due to its fifth and seventh harmonics. Whack-a-mole phenomenon occurs as an active filter or passive filter installed on the long feeder line. It effect harmonic voltage where increase on some busses and decrease on other busses, especially at point of installation. In this paper, the inverter replaced by directly connected with the current source. Thus, parallels current source with combination of fundamental, third, fifth and seventh harmonic frequencies were tested. From the analysis, the best location of inverter current source should be at least λ/4 from end bus. Thus, it proves by looking into its harmonic voltage, harmonic current and total harmonics distortion (THD) performance.
