Voltage Control Methodologies in Active Distribution Networks
Energies, 2020 Renewable Energy Sources are becoming widely spread, as they are sustainable and low-carbon emission. They are mostly penetrating the MV Distribution Networks as Distributed Generators, which has determined the evolution of the networks’ control and ...

Distributed Agreement on Activity Driven Networks [PDF]
2018 Annual American Control Conference (ACC), 2018 In this paper, we investigate asymptotic properties of a consensus protocol taking place in a class of temporal (i.e., time-varying) networks called the activity driven network. We first show that a standard methodology provides us with an estimate of the convergence rate toward the consensus, in terms of the eigenvalues of a matrix whose computational

Optimal Protection Coordination of Active Distribution Networks With Synchronverters
IEEE Access, 2022 Synchronverters are inverters imitating synchronous generators (SGs) to curb adverse impacts of traditional inverters on power networks. However, synchronverters may generate unlimited currents during faults.

Impact of Active Distribution Networks on Transient Stability
2022 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe), 2022 The increasing penetration of distributed energy resources (DERs) has turned passive distribution networks into active, in turn affecting the dynamic behavior of the system. It is essential to investigate to what extent transmission system dynamics are affected by these changes. This paper aims at identifying the impact of active distribution networks (

Multiarea Voltage Controller for Active Distribution Networks
Energies, 2018 The aim of this paper was to develop a multi-area decentralized controller for improving the voltage profile of large active distribution networks. Voltages at control buses of each area are kept as close as possible to their reference values by managing
