DC grids


What is needed to build future DC grids?

DC grids should be able to operate during different operation modes in the connected AC-systems as well as in the DC-system, i.e. Normal operation Alert state Emergency state Failure state

DC grids can be divided into Regional DC grids Interregional DC grids


Regional DC grids Can be built now with existing, proven technology

A DC regional grid is defined as a system that constitutes of one protection zone

Characteristics

It can be realized today with proven technology. There are no technology gaps to be closed.

DC breakers are not needed

Normally radial or star network configuration

Regulatory issues such as how to manage such new grids need to be solved


Trans-European or interregional DC grids

A DC interregional DC grid is defined as a system that needs several protection zones

There are existing technology gaps to be closed before realization (ongoing), for example

DC breakers are required

Power flow control is needed

Automatic network restoration

DC/DC converters for connecting different regional systems can be used

Regulatory issues such as how to manage such new grids need to be solved


HVDC Light Connecting wind farms

System with converters and cables Easier permit procedure in coastal areas Low project risk Short installation and implementation time Low operation and maintenance cost

Grid improvement Voltage and reactive power control Loss reduction in connected AC network Increased transfer capability in AC lines Connection in weak network points Passive load operation (Black Start)

Environmentally adapted Short permitting time Small footprint and low profile of converters Oil free cable Reduced magnetic fields “Invisible” transmission
