Lightning-induced voltages are one of the main causes of shutdown in distribution lines. In this work, attention is focused on the effects of wideband modeling of electric grounding in the overvoltage calculation along insulator strings due to indirect lightning strikes. This study is done directly in the time-domain with the grounding being...

In the new energy scenario Renewable Energy Sources are playing a central role especially if energy islands are concerned. In particular, energy islands without synchronous generation, for example photovoltaic storage, are of major interest if one aims at a sustainable transition of these systems. In this Microgrid structure Grid-Forming and...

The primary regulation of photovoltaic (PV) systems is a current matter of research in the scientific community. In Grid-Feeding operating mode, the regulation aims to track the maximum power point in order to fully exploit the renewable energy sources and produce the amount of reactive power ordered by a hierarchically superior control level...

The increasing penetration of Renewable Energy Sources (RES) and, more in general, of converter connected power generation is progressively reducing the overall inertia of the electricity system introducing new challenges in the network Frequency Support (FS). Therefore, FS strategies for RES are becoming an important aspect to be developed in...

One of the most important and studied topics in lightning research is the development of suitable models for the return stroke current and electromagnetic fields. In particular, when dealing with the so-called engineering models, the definition of a function that expresses the attenuation of the current while flowing in the discharge channel...

Indirect lightning strokes represent and important source of damage for overhead distribution lines. For the correct evaluation of lightning-induced overvoltages, the frequency dependence of the electrical parameters of the soil should be considered. Therefore, this paper proposes a simplified approach which selects a dominant frequency...

A correct representation of the lightning current is crucial when the electromagnetic field radiated to a point of interest has to be computed. Based on the engineering models of Transmission Line type, such representation involves the knowledge of the return-stroke speed, the channel-base current, the channel height and the attenuation...

This paper aims at describing the activities and projects carried out at the Savona Campus of the University of Genoa to transform the Campus into an 'open-Air' laboratory, called 'Living Lab Smart City', in which experimenting the most innovative and sustainable technologies for the production, distribution and management of energy in the...
