Identification of Harmonic Injection and Distortion Power at Customer Location

Comparative Analysis of the Contribution of Harmonic Injection by PV Systems in Microgrids

“…Some harmonic detection methods have been proposed in several studies, such as: Anu and Fernandez (2020)…”

“…The physical nature of the distortion powers has its bases in the process of generating current harmonics and not must be confused with reactive power, but monitored separately (Emanuel (2012)). According to Anu and Fernandez (2020), harmonic injection at the Consumer's location can be quantified by a term known as harmonic distortion index (i HN ) which consists of the relationship between the total contribution of harmonic current (i h ) at the Consumer connection point and the fundamental current (I 1 ) of the consumer.…”

“…Distributed measurement methods provide accurate information about the harmonic state of the power system, but are difficult to implement, as they require complex and expensive measuring instrumentation. Single point measurement techniques are best suited to estimate the harmonic contribution at the customer's site due to easy implementation and low cost (Anu and Fernandez (2020)). Anu and Fernandez (2020), proposed a new harmonic distortion index (i HN ) to identify the harmonic contribution of non-linear loads.…”

Anu and Fernandez (2020), proposed a new harmonic distortion index (i HN ) to identify the harmonic contribution of non-linear loads. The detection method used was a single point, and the i HN was used to determine the contribution of harmonic injection into the DS of each consumer under analysis in relation to other consumers.…”

“…In this work, the methodology presented by Emanuel (2012) for the calculation of powers, under non-sinusoidal voltage and current conditions, and the harmonic distortion index (i HN ) proposed by Anu and Fernandez (2020) are extrapolated and used to determine the contribution of harmonic injection by PV generation systems and the effects on other consumers located in the same microgrid.…”
