Transmission planning is based on a careful assessment
of the expected development of generation – including
wind power – and demand, as well as an analysis
of the current network infrastructure (congestions/
replacement needs) to maintain security of supply. Input
for these analyses is delivered by a range of studies
as explained in the next section.
The development of offshore grids is of course part of
this process. However because of the specific issues
involved, offshore grids are dealt with in a separate
section (see page 106)

3.1 Recommendations from
European studies
Several studies at national and European level are
now underway to back up the plans for upgrading the
European transmission system in order to facilitate
large-scale wind power integration. The most important
recent international studies are TradeWind (www.
trade-wind.eu) and EWIS (www.wind-integration.eu).
Studies like these, which analyse the grid extensively
– including both steady-state load flow and dynamic
system stability analysis – are essential for quantifying
the reinforcement needed to maintain adequate
transmission with increasing wind power penetration.
