在可再生能源“界”，聽說(shuō)“把肉賣成大白菜價(jià)錢”(甚至倒貼錢)的，沒有聽說(shuō)“把大白菜賣成肉價(jià)錢”的。但在“創(chuàng)新”世界，“一切皆有可能”。據(jù)英國(guó)ReNews網(wǎng)17日?qǐng)?bào)道，丹麥輸變電系統(tǒng)運(yùn)營(yíng)商TSO Energinet和丹麥能源(Energi Danmark)貿(mào)易集團(tuán)，在TSO的DK2區(qū)，利用陸上風(fēng)能成功地實(shí)現(xiàn)了電網(wǎng)供-需平衡。還說(shuō)，初步試驗(yàn)表明，“各項(xiàng)試驗(yàn)結(jié)果......能履行事先承諾的目標(biāo)”，裝置還具有需要的“監(jiān)管屬性”。但外行人看“熱鬧”，內(nèi)行能看出“門道”。
丹麥的TSO Energinet和丹麥能源貿(mào)易集團(tuán)開發(fā)的項(xiàng)目正在進(jìn)行的初步試驗(yàn)。
這是丹麥?zhǔn)状问褂蔑L(fēng)能為輸電系統(tǒng)運(yùn)營(yíng)商TSO Energinet運(yùn)營(yíng)的電網(wǎng)提供“平衡”服務(wù)。
TSO說(shuō)，與丹麥能源貿(mào)易集團(tuán)合作的初步試驗(yàn)項(xiàng)目表明，盡管有風(fēng)有雨，風(fēng)力渦輪機(jī)是可靠的，可以在需要的時(shí)候準(zhǔn)確地提供服務(wù)。這次試驗(yàn)最初基于連接到東丹麥電價(jià)區(qū)(即DK2)的渦輪機(jī)。
Kundbyvaerket公司說(shuō)，到目前為止，參與試驗(yàn)的渦輪機(jī)一直處于停運(yùn)狀態(tài)，并將在2020年的剩余時(shí)間直到2021年繼續(xù)運(yùn)行。
TSO Energinet公司靈活性與系統(tǒng)服務(wù)負(fù)責(zé)人Kia Marie Jerichau(上圖,左)說(shuō)，“直到現(xiàn)在,我們一直不確定，是否能足夠安全的讓風(fēng)力渦輪機(jī)投標(biāo)并提交電網(wǎng)平衡市場(chǎng)。例如，周一是否可以準(zhǔn)確地預(yù)測(cè)風(fēng)力渦輪機(jī)組能在周二一小時(shí)接一小時(shí)地連續(xù)運(yùn)行多長(zhǎng)時(shí)間。

丹麥能源貿(mào)易集團(tuán)部門主管Thomas Elgaard(上圖，右)說(shuō)，“我們很高興，我們的模型和預(yù)測(cè)這么可靠，Energinet能與傳統(tǒng)電廠一樣地確保安全。”
“我們已經(jīng)并將繼續(xù)投入大量資源，以證明，可再生能源不僅是綠色轉(zhuǎn)型的答案，還有助于解決未來(lái)的電網(wǎng)平衡的挑戰(zhàn)。”

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.”
