Interconnect grids

HVDC enables the exchange of energy between two AC networks. In some

cases, this is the only means of neighboring utilities exchanging energy

since they operate at different frequencies or may not be synchronized.

An HVDC interconnection has many benefits, such as allowing neighboring

utilities to reduce and share ‘spinning reserve’, giving access to other lower

cost sources of energy.

Improve quality, stability and maximize network performance

All HVDC solutions provide a ‘firewall’ to prevent disturbances propagating

from one network to another. They provide fast and highly controllable

power transfer and today can provide reactive power into the local AC

network to improve stability and quality.
