Sweden, Norrbotten: Sweden is leading the green energy transition journey, directing the nation’s electricity to run on 100 % renewable energy by 2040.
To meet this target, wind energy generation needs to triple the current annual output of 30 TWh to at least 90 TWh.
The Markbygden wind farm will play a key role in the Swedish energy transition and is envisioned to become Europe’s largest onshore windfarm with the capacity to produce electricity of up to 12 TWh per year. It will comprise of almost 1,000 wind turbines and is currently under construction in the Norrbotten county in northern Sweden.
Renewable energy facilities such as wind farms face several power quality challenges. In particular, large and sudden fluctuations in power output are caused by unpredictable weather conditions and varying wind speeds, which can create significant disruptions in the grid. Additionally, excessive reactive power demand and harmonics can limit the actual energy output from wind turbines, causing power losses. Furthermore, penalties can be imposed to wind farms owners if they fail to comply with the grid codes requirements.
In order to integrate renewable resources at such a large scale, Hitachi Energy is deploying harmonic filters at the Råbäcken substation, an essential transmission hub in the Markbygden wind farm power infrastructure. This innovative solution will contribute to secure voltage stability, avoid network losses and improve power quality.
“Hitachi Energy’s harmonic filters will support full utilization of the renewable power generated from the wind turbines,” said Tobias Hannu, Chief Technical Officer, Markbygden Net. “The increase in power quality will also ensure that we meet the high-level requirements of the main grid. It will help us to avoid disturbances for stable operations, making us a reliable partner in balancing the reactive power from a national perspective.”
