Vattenfall's new wind farms off the west coast of Jutland in Denmark not only provide renewable energy to Danish consumers, but for the first time ever they are part of an agreement to actively supply strength to the electricity grid in the West Jutland region. In addition to increasing Danish electricity generation from wind turbines by more than 10 per cent, they will be able to actively deliver some of the voltage stability the network needs to maintain the reliable power grid for which Denmark is so famous.
Like small power plants
"A wind turbine is now just as large as a small combined heat and power plant of almost 10 MW, so we can really deliver some strength to the grid, which would otherwise come from power plants. But there aren't many of those in the area where Vesterhav Syd and Nord are being built," explains Kenneth Skaug, Senior Engineer in the System Design department at Vattenfall.
"It's all about magnetic fields, electric fields and frequencies that need to be controlled and monitored carefully so that we can all heat up our scalloped potatoes and lasagne for dinner, get some cold milk from the fridge and make the TV, computers and lights work," adds Skaug with a twinkle in his eye, aware that this is probably not the place for more in-depth technical explanations.
