Support of VSC-HVDC to the restoration of weakly connected systems: the Sardinia case

La memoria illustra i potenziali benefici di un collegamento VSC-HVDC nel ripristino del sistema elettrico sardo in uno scenario al 2020, assumendo il rifacimento con tecnologia VSC del collegamento HVDC SACOI (Sardegna-Corsica-Italia).

The paper illustrates the potential benefits of a VSC-HVDC link in the restoration of the Sardinian power system in a 2020 scenario. In particular, the paper envisages the upgrade of the existing SACOI (Sardinia-Corsica-Italy) HVDC link by adopting VSC technology, and it compares a conventional restoration scenario of Sardinia against scenarios where the VSC-based SACOI supports the restoration process, acting either as a black start unit or as a reactive power support device (STATCOM).

The VSC allows to achieve advantages such as greater flexibility in the restoration process and stable control of the operating quantities. The work herein reported has been carried out in the context of Demo 3 of the Best Paths EU research project.
