The topic of microgrids (MGs) is a fast-growing and very promising field of research in terms
of energy production quality, pollution reduction and sustainable development. Moreover …

Natural disasters can cause significant damage to power grids. During summer, in countries
with high temperatures, distribution systems passing through forested areas are prone to …

The optimal control of distribution networks often requires monitoring and communication
infrastructure, either centralized or distributed. However, most of the current distribution …

This paper describes the two test systems for voltage stability studies set up by the IEEE PES
Task Force on “Test Systems for Voltage Stability Analysis and Security Assessment” under …

The paper proposes a control scheme to improve the dynamic response of power systems
through the automatic regulators of converter-based Distributed Energy Resources (DERs) …

The increasing installation of controllable Distributed Energy Resources (DERs) in
Distribution Networks (DNs) opens up new opportunities for the provision of ancillary …

A reduced-order,“grey-box” model of an active distribution network, intended for dynamic
simulations of the transmission system, is derived. The network hosts inverter-based …

In the last years, the energy production share of power electronics-based generators has
kept increasing with respect to the synchronous generation. These power electronics …

Reduced rotational inertia in power grids due to increasing penetration levels of distributed
