在可再生能源“界”，聽說“把肉賣成大白菜價錢”(甚至倒貼錢)的，沒有聽說“把大白菜賣成肉價錢”的。但在“創新”世界，“一切皆有可能”。據英國ReNews網17日報道，丹麥輸變電系統運營商TSO Energinet和丹麥能源(Energi Danmark)貿易集團，在TSO的DK2區，利用陸上風能成功地實現了電網供-需平衡。還說，初步試驗表明，“各項試驗結果......能履行事先承諾的目標”，裝置還具有需要的“監管屬性”。但外行人看“熱鬧”，內行能看出“門道”。
丹麥的TSO Energinet和丹麥能源貿易集團開發的項目正在進行的初步試驗。
這是丹麥首次使用風能為輸電系統運營商TSO Energinet運營的電網提供“平衡”服務。
TSO說，與丹麥能源貿易集團合作的初步試驗項目表明，盡管有風有雨，風力渦輪機是可靠的，可以在需要的時候準確地提供服務。這次試驗最初基于連接到東丹麥電價區(即DK2)的渦輪機。
Kundbyvaerket公司說，到目前為止，參與試驗的渦輪機一直處于停運狀態，并將在2020年的剩余時間直到2021年繼續運行。
TSO Energinet公司靈活性與系統服務負責人Kia Marie Jerichau(上圖,左)說，“直到現在,我們一直不確定，是否能足夠安全的讓風力渦輪機投標并提交電網平衡市場。例如，周一是否可以準確地預測風力渦輪機組能在周二一小時接一小時地連續運行多長時間。
“但這個項目表明，預報如此之好，以至于可提前兌現承諾，而且這些裝置有需要的監管屬性。” “這是綠色轉型的一個重要里程碑：先決條件是，整個電力系統是綠色的，可再生能源能提供平衡服務。”
丹麥能源貿易集團部門主管Thomas Elgaard(上圖，右)說，“我們很高興，我們的模型和預測這么可靠，Energinet能與傳統電廠一樣地確保安全。”
“我們已經并將繼續投入大量資源，以證明，可再生能源不僅是綠色轉型的答案，還有助于解決未來的電網平衡的挑戰。”
“我們在初步試驗中看到的情況非常正面，而這只是一個起點，更多、其他形式的可再生能源，也可以幫助電網保持平衡，并在未來參與各種的市場。”

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.”
