The Danish transmission system operator (TSO) published an extensive report discussing how Denmark reached high wind power penetration levels in the national power system. Adaptation to and integration of the Danish power system with wind power may be an example for countries still facing numerous barriers to development of the sector.
The Danish energy policy focused on wind power industry. Today, more than 20% of electricity is produced in 5200 onshore and offshore wind turbines. To make this possible, tools allowing for integrating large amounts of wind energy with the power system had to be developed. The tools include everything necessary, from modern power grid planning and construction solutions, through precise wind forecasting and appropriate capacity reserves in calm days, to sound energy market, where participants, through trade, balance the market on their own. This allows for a fully balanced energy market, taking into account the fluctuations stemming from variations in wind speed or consumers’ behavior.
The document also presents the assumptions planned to be implemented in Denmark to reach 50% share of wind energy in 2025. An essential part in this strategy is the use of electric-powered cars. The plan assumes that car batteries will be an important tool used to balance the power system through consumption of surplus wind energy when supply exceeds demand; when demand exceeds supply, the batteries could feed electricity to the system. The first car capable of intelligent collaboration with the power system is to be manufactured within three to four years.
