Cable Effects on Noise Propagation in Distribution Networks with Renewable Sources

In energy distribution networks, conducted emissions (CE) from power electronic converters pose increasing challenges in terms of coexistence with communication systems, such as powerline communications. To understand the propagation of CE, this study modeled and simulated a medium/low voltage distribution network in the frequency domain to assess the level of “noise” in different branches of the network. The analysis highlighted the need for accurate modeling using transmission line theory to account for various cable characteristics, such as parameters per unit length, length, and terminal conditions.

The increasing deployment of power electronics for integrating renewable energy generation systems into distribution networks brings growing challenges in terms of coexistence with communication systems, such as powerline communication devices. This is due to high-frequency noise currents, conducted emissions (CE), generated by power electronics converters, which propagate along the network through power cables.

 

With the aim of providing guidelines to ensure coexistence with communication systems, this study modeled and simulated a medium/low voltage distribution network in the frequency domain. The analysis aims to predict noise currents in different branches of the network and identify factors that can significantly influence their propagation. The analysis focuses primarily on the effects due to power cables and highlighted the need for accurate modeling using transmission line theory to account for various cable characteristics, such as parameters per unit length, length, and terminal conditions.
