溫帶氣旋Ciara過境德國促成德國全境風力發電量創下新高紀錄,風電發電量佔比達60%,整體再生能源總發電量佔比高達全國用電量的75%驚人紀錄! (Clean Energy Wire 02/11/2020)
Storm 'Ciara' blows German wind power production to new record
是的看清楚,即使是暴風雨來襲的期間,風力發電還是可以持續發電的,而且往往趁勢創下發電量新高紀錄!再生能源科技持續的在向前推進,發電效能越來越好,抗候性越來越佳,發電成本越來越低廉,整體環保、減碳效益持續提升,而且整體電力調度的配套解決方案也越來越精進且智慧化!這就是目前整個世界能源領域正在每天發生的事實!
via Tony Yen : "因為溫帶氣旋Ciara光臨中歐,全歐洲的風力發電過去幾天大增,其中德國甚至創下風能瞬間發電量43.7GW的歷史新高紀錄。
在2月9日和2月10日,整體再生能源發電一度佔了德國全國用電量的75%佔比,單單風能就佔了60%比率。此外,這兩天風能也佔了全歐洲發電量的27%。
News 11 Feb 2020, 13:36 Benjamin Wehrmann Storm 'Ciara' blows German wind power production to new record
by Renewables Wind dpa / Deutschlandfunk / Clean Energy Wire
The storm dubbed "Ciara" has pushed wind power production to a new record in Germany, temporarily boosting feed-in into the grid to nearly 43.7 gigawatts (GW), grid operator TenneT told news agency dpa in an article carried by public broadcaster Deutschlandfunk. The previous record stood at 43.4 GW. According to energy think tank Agora Energiewende*, renewables covered about three quarters of Germany's power consumption on 9 and 10 February, with onshore and offshore wind turbines contributing the lion's share. However, the storm also caused troubles for grid operators, since the record feed-in happened intermittently and even caused some turbines to be shut down for safety reasons, the article says.
According to the website energy-charts by research institute Fraunhofer ISE, wind power alone covered nearly 60 percent of net power production on 10 February, dwarfing coal-fired power production, which stood at about 11 percent on that day.
Wind, solar and other renewable sources supplied almost 43 percent of gross German power consumption in 2019, up from 38.2 percent in 2018. This marked a new annual record that already exceeds the government’s 2020 target of 35 percent, but the unprecedented output level is overshadowed by a near halt in onshore wind development. The number of new wind turbines recently fell to unprecedentedly low levels and the country is veering off track in reaching its 2030 target of a 65 percent renewables share."

太陽能廠夜間並非無用,英國發現竟可用來提高電網穩定性!! (11/26/2019 TechNews科技新報)
太陽能作為間歇性能源,常被人們認為是造成電網不穩定的因素之一,但英國太陽能廠商最新實驗指出,雖然說太陽能板在夜間無法發電,但可在夜晚維持電網電壓起伏,在未來全天都能扮演著重要的供電角色。
作者 Daisy Chuang
太陽能顧名思義,透過太陽能板吸收光並轉換成電力,天氣晴朗豔陽高照發電裝況就佳,可在日間提供龐大電力,但遇上陰雨綿綿天氣、天色暗下,就沒有電可用了,因此太陽能一直以來就有供電不穩定的疑慮,甚至會危及電網的穩定性,不過最近英國太陽能開發商 Lightsource BP 研究扭轉了大家對太陽能廠的印象。
Lightsource BP 表示,只需要花少少的錢調適系統,太陽能場就能在短短兩秒內平衡電網供電。該公司最近在東薩塞克斯郡的太陽能電廠進行實驗,在晚間時透過太陽能廠調整電網電壓波動,以行動證明太陽能電廠的功用不僅日間發電如此。
該公司營運長 Kareen Boutonnat 表示,「太陽能電廠在整體供電系統中,可以發揮更大效用,而我們的測驗只是剛開始而已。」
在太陽能系統中,太陽能逆變器主要負責將直流電轉換成交流電,也是重要的智慧接口,而 Lightsource BP 則運用逆變器在晚上幫助穩定電網起伏,英國衛報報導指出,未來英國將能藉此省下 4 億英鎊的電網翻新或建造新電廠成本,並增加 4GW 的發電容量。
目前許多太陽能逆變器都有搭載虛功率(Reactive power)調節功能,可以最佳化電壓穩定度,降低電網的調節壓力,未來太陽能電廠也能當作平衡電網的小幫手,在風能發電量高、用電需求低的時候,太陽能廠能避免電壓過高;風力發電量過低、電力需求高時,則用來防止電壓太低。
Lightsource BP 技術總監 Chris Buckland 表示,逆變器能將電力系統網路的電壓反射,以不同的電平回到電網中。未來 Lightsource BP 預計會在 12 月進行第二次實驗,同時也希望能在 2020 年與英國國家電網公司簽下商業協議。
