This paper describes an approach to estimate the flexibility of an Active Distribution Network
(ADN) to provide ancillary services across voltage levels by the regulation of the power flow …

A case study dealing with long-term voltage instability in systems hosting active distribution
networks (DN) is reported in this paper. It anticipates future situations with high penetration …

The large-scale integration of renewable generation and the gradual decommissioning of
conventional power plants has led to decreased availability of resources for providing …

The electrical energy generated from renewable energy resources connected to
transmission and distribution systems and the displacement of synchronous generators …

The provision of voltage support from distribution systems to transmission networks requires
new cost-effective coordination schemes to drive thousands of non-centrally monitored …

This paper proposes a distributed voltage control (DVC) scheme for smart distribution
networks with high penetration of inverter-based distributed generators (DGs), aiming to …

The paper presents an approach for online centralized control in active distribution
networks. It combines a proportional integral (PI) control unit with a corrective control unit …

The exchange of reactive power at the interface between distribution and transmission
systems gains significant importance with ongoing relocation of generators to lower voltage …

Hosting an increasing share of distributed generation and flexible consumers, distribution
systems are being more often considered as providers of ancillary services among which …

This article describes a novel power system architecture and operational concept which is
founded on the idea of organising sets of distributed generators, loads, storages and …
