The large penetration of distributed generation requires accurate line and cable models in a frequency range much wider than the classical interval, 0-2.5 kHz, used for traditional harmonic and interharmonic penetration studies. In the paper, the behavior of MV cable lines is considered in the frequency range from 0 to 100 kHz, with reference to a casestudy. Models base on the classical Π and Γ line equivalent circuits are considered. Reference is made to open and short circuited line input terminals conditions. A comparison of the performances of different complexity models, in terms of impedance magnitude accuracy at output terminal, is developed.

Abstract
The large penetration of distributed generation requires accurate line and cable models in a frequency range much wider than the classical interval, 0-2.5 kHz, used for traditional harmonic and interharmonic penetration studies. In the paper, the behavior of MV cable lines is considered in the frequency range from 0 to 100 kHz, with reference to a casestudy. Models base on the classical Π and Γ line equivalent circuits are considered. Reference is made to open and short circuited line input terminals conditions. A comparison of the performances of different complexity models, in terms of impedance magnitude accuracy at output terminal, is developed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
