Modeling and Analysis of Supraharmonic Propagation for Stochastic Studies
Ángela Espín-Delgado, Sarah Rönnberg
Abstract
Supraharmonic propagation depends on the impedance of both the grid and the devices connected to it. Few attempts to quantify the impact of the customer’s load variability have been done. The interest of grid operators is in counteracting the supraharmonic propagation upstream to maintain power quality. Quantifying the impact of impedance on supraharmonic propagation gives information to strategically counteract this propagation to the grid. This article presents a method for analysis of supraharmonic propagation that uses a stochastic approach to describe the impact of low-voltage (LV) loads. Scenarios of a strong and a weak grid are presented to study the impact of reinforcement grid measures.
