在可再生能源“界”，听说“把肉卖成大白菜价钱”(甚至倒贴钱)的，没有听说“把大白菜卖成肉价钱”的。但在“创新”世界，“一切皆有可能”。据英国ReNews网17日报道，丹麦输变电系统运营商TSO Energinet和丹麦能源(Energi Danmark)贸易集团，在TSO的DK2区，利用陆上风能成功地实现了电网供-需平衡。还说，初步试验表明，“各项试验结果......能履行事先承诺的目标”，装置还具有需要的“监管属性”。但外行人看“热闹”，内行能看出“门道”。

丹麦的TSO Energinet和丹麦能源贸易集团开发的项目正在进行的初步试验。

这是丹麦首次使用风能为输电系统运营商TSO Energinet运营的电网提供“平衡”服务。

TSO说，与丹麦能源贸易集团合作的初步试验项目表明，尽管有风有雨，风力涡轮机是可靠的，可以在需要的时候准确地提供服务。这次试验最初基于连接到东丹麦电价区(即DK2)的涡轮机。

Kundbyvaerket公司说，到目前为止，参与试验的涡轮机一直处于停运状态，并将在2020年的剩余时间直到2021年继续运行。

TSO Energinet公司灵活性与系统服务负责人Kia Marie Jerichau(上图,左)说，“直到现在,我们一直不确定，是否能足够安全的让风力涡轮机投标并提交电网平衡市场。例如，周一是否可以准确地预测风力涡轮机组能在周二一小时接一小时地连续运行多长时间。

“但这个项目表明，预报如此之好，以至于可提前兑现承诺，而且这些装置有需要的监管属性。” “这是绿色转型的一个重要里程碑：先决条件是，整个电力系统是绿色的，可再生能源能提供平衡服务。”

丹麦能源贸易集团部门主管Thomas Elgaard(上图，右)说，“我们很高兴，我们的模型和预测这么可靠，Energinet能与传统电厂一样地确保安全。”

“我们已经并将继续投入大量资源，以证明，可再生能源不仅是绿色转型的答案，还有助于解决未来的电网平衡的挑战。”

“我们在初步试验中看到的情况非常正面，而这只是一个起点，更多、其他形式的可再生能源，也可以帮助电网保持平衡，并在未来参与各种的市场。”

Danes deploy wind for balancing first

17 December 2020

The ongoing pilot project has been developed by TSO Energinet and trading group Energi Danmark

Wind energy has been used for the first time in Denmark to provide balancing services for the grid run by transmission system operator Energinet.

The TSO said the pilot project in partnership with trading group Energi Danmark shows that wind turbines, despite wind and weather, are reliable and can deliver exactly when needed.

The pilot has initially been based on turbines connected to the East Danish electricity price area, known as DK2, Energinet said.

The turbines have so far participated in the period in which Kundbyvaerket has been out of operation, and will continue to run for the rest of 2020 and into 2021, the company said.

Energinet head of flexibility and system services Kia Marie Jerichau (pictured, left) said: “Until now, we have been unsure whether it was safe enough to let wind turbines bid and deliver to the balance market – whether, for example, on Monday one could accurately predict how much a group of wind turbines would produce hour by hour on Tuesday.

“But the project shows that the forecasts are so good that they can deliver what they have promised in advance, and that the plants have the necessary regulatory properties.

“This is a major milestone for the green transition – it is simply a prerequisite that renewable energy sources can also provide balance services when the entire electricity system must be green.”

Energi Danmark division director Thomas Elgaard (pictured, right) said: “We are very pleased that our models and forecasts are so reliable that Energinet has security for delivery in line with conventional power plants.

“We have invested, and continue to invest, many resources in showing that renewable energy, in addition to being the answer to the green transition, can also contribute to solving future challenges with balancing the electricity grid.

“What we have seen in the pilot test has been extremely positive, and it is only the starting point that more and other forms of renewable energy can help balance the grid and participate in different markets in the future.”
