Modelling and Simulation of Unintentional Emissions in the Frequency Range 2-150 kHz

In the new scenario of Energy Transition, the electrical power systems will use more and more power Electronic devices to interface loads, dispersed generation, and storage systems, at all voltage levels. The switching frequencies adopted by new generation power electronic apparatus are increasing, thanks to the availability of faster high power switches, to increase efficiency and controllability. This trend is changing the scenario of the harmonic pollution analyses and the traditional interval of frequencies of interest (0 – 2.5 kHz) focusing on a wider interval (0 -150 kHz). Understanding and resolving issues in this frequency range needs a deeper understanding of the emission, their summation, and propagation in the networks, which in turn requires comprehensive models and simulations. This panel session provides an overview of the present state of research in terms of modelling unintentional emission in the frequency range 2-150 kHz and illustrates their application by case studies.
