Dutch electricity system can cope with large-scale wind power (energy storage not needed)

Dutch electricity system can cope with large-scale wind power

23 February 2009 by M&C

Research by TU Delft proves that Dutch power stations are able to cope at any time in the future with variations in demand for electricity and supply of wind power, as long as use is made of up-to-date wind forecasts. PhD candidate Bart Ummels also demonstrates that there is no need for energy storage facilities. Ummels will receive his PhD on this topic on Thursday 26 February.

Wind forecast

His results indicate that wind power requires greater flexibility from existing power stations. Sometimes larger reserves are needed, but more frequently power stations will have to decrease production in order to make room for wind-generated power. It is therefore essential to continually recalculate the commitment of power stations using the latest wind forecasts. This reduces potential forecast errors and enables wind power to be integrated more efficiently.

Ummels looked at wind power up to 12 GW, 8 GW of which at sea, which is enough to meet about one third of the Netherlands’ demand for electricity. Dutch power stations are able to cope at any time in the future with variations in demand for electricity and supply of wind power, as long as use is made of up-to-date, improved wind forecasts. It is TenneT’s task to integrate large-scale wind power into the electricity grid. Lex Hartman, TenneT’s Director of Corporate Development: “in a joint effort, TU Delft and TenneT further developed the simulation model that can be used to study the integration of large-scale wind power. The results show that in the Netherlands we can integrate between 4 GW and 10 GW into the grid without needing any additional measures.

No energy storage

Ummels’ research also demonstrates that energy storage is not required. The results indicate that the international electricity market is a promising and cheaper solution for the use of wind power.
