In modern power systems voltage source converters (VSCs) are often used for interfacing renewable distributed generation units. To evaluate the impact on power quality of the widespread use of VSCs proper models and methods have to be developed and investigated. In this paper, a review of harmonic models in the frequency domain is carried out and Norton-based models are applied and compared in terms of computational complexity and accuracy. For this purpose, a 12 kW photovoltaic plant (of the type typically found in low voltage distribution networks) is analysed for a range of operating conditions.

Abstract
In modern power systems voltage source converters (VSCs) are often used for interfacing renewable distributed generation units. To evaluate the impact on power quality of the widespread use of VSCs proper models and methods have to be developed and investigated. In this paper, a review of harmonic models in the frequency domain is carried out and Norton-based models are applied and compared in terms of computational complexity and accuracy. For this purpose, a 12 kW photovoltaic plant (of the type typically found in low voltage distribution networks) is analysed for a range of operating conditions.File in questo prodotto:
