Characterize the harmonic emission of nonlinear loads

The rising amount of nonlinear loads requires a closer consideration of their impact. A high level of supply voltage quality should be maintained. Therefore, constraints or incentives should be applied to harmonics-producing loads in order to reward beneficial behaviors and penalize malevolent ones. Based on the observation that peak instantaneous harmonic power tends to be very large compared to the near-zero average harmonic power, this paper propose a new emission assessment method based on the concept of friendliness power. This work focus on periodic emissions in networks that have X/R ratios of about two or less, which represent most distribution systems.
