智慧電網技術產業發展趨勢

立法院通過溫室氣體減量及管理法,2050年溫室氣體排放量降為2005年排放量50%。政府推動2025年達成非核家園政策目標,綠能發電比例提升至20%。未來台灣將經歷重大的能源與社會轉型工程。台灣各區域能源利用與再生能源特色有其特色例如北部地區尖峰用電仰賴南電北送,為大型能源需求中心以需量管理為核心。中部地區擁有離岸及陸上風力發電資源。南部地區太陽光電設置占全國70%以上,配合儲能系統可整合成為南部虛擬電廠。東部地區則有地熱、海洋能資源豐富。

立法院於2017年通過「電業法」修正案,於電業劃分中新增再生能源發電業及綠能售電業。台灣未來能源轉性工程需以區域能源利用與再生能源特色為主軸,建立各區域所屬能源轉型策略,由地方的需求帶動技術創新並加強地方參與,確保可連結地方特色與願景與地方共榮。可預見未來間歇性再生能源比例增加,需由中央與地方合作推動大型區域能源展示櫥窗,藉由智慧電網及虛擬電廠商業運轉模式驅動區域智慧能源轉型工程,使再生能源可融合傳統能源供應體系運作。

Study on the Promotion Method of Smart Grid Integration in Smart Cities (SDEWES2016.0047)

This study is aimed to analyze the development trends of the integration of a smart low-carbon city and virtual power plant technology, propose the promotion strategies for smart grid in urban areas, analyze the conditions and opportunities for Taipei City to develop a smart grid, and finally introduce the phase zero smart grid plan for Xinglong Public Housing in Taipei City.



Analysis of Levelized Cost of Kuroshio Energy in Taiwan (SDEWES2016.0024)

Taiwan is surrounded by sea with 1,566 km of coastline. A primary assessment of marine energy that incorporates the energy reserves, derivative economic benefit, cleanness and sustainability, energy stability, and cost competitiveness shows that wave energy, thermoelectric energy, and marine current energy have the greatest potential for development in Taiwan. Among them, the fixed direction of current flow gives it a great deal of potential for power generation, and thus it has started to draw attention in many counties. The Kuroshio off the east coast of Taiwan is part of the global ocean current system. If ocean current power generation technology can be successfully developed, its power generation efficiency would be greater than that of intermittent energy such as solar and wind. Power generation from the Kuroshio can provide the base load electricity in Taiwan, increasing Taiwan’s self-sufficiency rate and safety of energy. However, the initial phase of developing the Kuroshio power generation in Taiwan requires huge capital investment, and issues such as economic benefit and market competitiveness must be considered.

The levelized cost of electricity (LCOE) for natural gas-fired in the main island of Taiwan is about 3.6 NTD/kWh, and the average cost of electricity in Green Island (one of Taiwan's Offshore Islands) is about 13.5 NTD/kWh. In order to let Kuroshio power be competitive in market, this report presents an analysis of the LCOE for the development of Kuroshio power generation under three different scenario in Taiwan, 2MW, 30MW and 110 MW scenario respectively. Based on the scenario analysis of Taiwan's first 30MW Kuroshio power demonstration farm development, the LCOE is around 4.86-11.17 NTD/kWh at a discount rate of 15%, which is still higher than TaiPower's natural gas power generation cost of 3.57 NTD/kWh. In order to increase the industry’s willing to invest in Kuroshio power development, it is necessary to have the support from the government. Taiwan government could formulate marine spatial planning properly, doing preliminary investigation to zone the area suitable for Kuroshio power development, it would reduce more project cost.

TSGIA Interview at ASUW16 - Taiwan's Smart Grid Evolution



The future of Taiwan’s smart grid Interview with Chen Yenhaw, Deputy Secretary-General, Taiwan Smart Grid Association. By Jasmine Gan. 5 AUG 2019

"Smart grid” has already become old news in Taiwan. Installation of smart meters in residential and industrial systems alike are proceeding at a rapid pace, with 200,000 new smart meters installed every year by Taipower, Taiwan’s monopoly utility provider. By the end of the year, half of the island will be equipped with smart meters: a total of 6 million installations.

“Installation is not so important now,” says Chen Yen-haw, Deputy Secretary-General of the Taiwan Smart Grid Association. Instead, current research in Taiwan on smart grid has moved to focus on commercial application of the technology. With major changes in Taiwan’s energy landscape, including the recent liberalisation of their renewable energy market and President Tsai’s nuclear-free homeland policy, the challenge will be how to best adapt the mature tech for their purposes. According to Chen, Taiwan’s new priorities will be on developing strategies for demand-side management, refining battery storage solutions, and further innovation in business models.

Demand-side management

Widespread adoption of smart grid tech has led to two major changes in Taiwan, says Chen. The first has been the ability to engage in demand-side management, as smart meters and real-time data make it possible to manage energy demand through price signals.

Recently, Taipower introduced tiered pricing, where participating customers can receive discounted tariffs for off-peak use of energy to encourage energy conservation during peak hours. Another innovative demand-side management strategy is to create a “virtual account” for customers, who can join in groups of 10 to work together to lower their aggregate electricity use in peak hours.

Energy shortage has become a major challenge for the island as Taiwan shifts away from nuclear power, and efforts to conserve energy through demand-side management could help mitigate that.

The rise of the prosumer

The second impact of smart grid adoption has been the greater control of customers over their own energy consumption. “Now customers can choose from different suppliers, different tariffs, different pricing,” says Chen. “Since we opened our energy market in renewables, there will be new renewable retailers and developers.”

Residential solar systems are becoming more common, as the widespread installation of smart inverters allow customers to store and manage energy generated from their own solar panels. These prosumers, customers who consume and produce their own electricity, are a growing presence in Taiwan’s energy market, according to Chen. In Taipei City, a virtual power plant system has been developed to allow prosumers to contribute surplus electricity from their home solar system back to the grid.

For Taiwanese communities living in remote islands, the government has subsidised installation of smart micro-grid systems that integrate renewable energy sources. The mix of solar, wind and diesel energy sources ensure a stable electricity supply despite distance from the central grid. On the remote Qimei Island, 43% of the inhabitants’ energy is now supplied by renewable energy through the smart micro-grid. “The micro-grid technology is very mature now,” says Chen.

But is Taiwan close to moving away from fossil fuels entirely? The main driving force of the recent uptake of renewable energy is the dropping cost of wind and solar systems, says Chen. However, the battery storage for renewables needs further refining. “The efficiency of solar increases by 1-2% every year,” explains Chen. “But the battery system is still not mature enough for real commercial application.” There will need to be a breakthrough in storage solutions before renewables can replace fossil fuels in Taiwan.

A future for energy trading

More development on the business side could lead to truly innovative applications of the advanced technology. Chen envisions cooperation between governments, private sector actors and consumers to come up with ways to utilise smart grid solutions.

A recent example is the collaboration between Taiwan Smart Grid Association and Gogoro, an electric scooter manufacturer, to create a smart grid from its scooter battery charging stations. With charging stations every 1.3km in Taipei, the company provides electricity to the grid when the solar-powered stations are not being used to charge batteries. “Five years ago, the scooter manufacturers came to my office and told me they were building a massive battery system,” Chen recounts. “I told them from the power system’s perspective, we will have the need.”

The cooperation need not be managed by the government. “I’m not really a guy who is familiar with scooters,” says Chen. “But we worked together. It was a bottom-up, multi-disciplinary process.”

Chen envisions that in the future, similar models for energy trading across private power sources and public power plants will be possible through a common platform for the whole country. “A platform like this could be the future for the whole power system,” says Chen.

This kind of multi-industry, multi-actor conversation is already beginning to happen. Taiwan’s adoption of smart grid has opened up new doors for further innovation.

台灣大規模布建太陽光電之挑戰-以虛擬電廠模式提升再生能源利用作法

因應未來非核家園與溫室氣體減量目標,新政府能源政策將擴大太陽光電及離岸風電等再生能源利用,並加速智慧電網與電表佈建。2025年前推廣太陽光電20GW(屋頂3GW / 地面型 17GW)、風力發電4.2GW(陸上1.2GW、離岸3GW),屆時再生能源將佔總發電容量的53.1%,總發電量的18.5%。800萬民生用戶建置智慧電表連結智慧電網。大規模推廣太陽光電主要限制在可使用面積或可裝置建築數量,台灣地狹人稠,如何持續提供可設置太陽光電板所需面積,為大規模推廣太陽光電最重要挑戰。參考先進國家再生能源推廣經驗,隨著太陽能發電與風力發電等裝置容量增加,電網對間歇性發電的可接納容量也將使再生能源的擴大利用產生限制。隨著再生能源與儲能成本下降,用戶自發自用意願上升,如何利用智慧電網建立商業模式及配套制度,擴大需量管理、分散式電源、儲能整合系統進入電力市場,為再生能源納入台灣能源供應體系急需發展方向。

台灣發展黑潮發電之均化成本分析

台灣四面環海,以能源蘊藏量、衍生性經濟效益、潔淨永續、能源穩定性以及成本競爭性對海洋能源進行初步評估,則波浪、溫差與洋流能最具有發展性。其中,洋流的流向固定,發電潛能大,在許多國家開始受到關注。台灣東部海域的黑潮即為全球洋流系統的一環,若能成功開發洋流發電技術,則發電效益較太陽能、風力等間歇性能源佳的黑潮發電將有望成為我國基載電力,提升能源自給率及安全性。然而台灣開發黑潮發電前期需投入龐大資金,需要考慮經濟效益以及市場競爭力,故本研究將分析台灣發展黑潮發電之均化成本以及各成本區塊之比例,以探討成本下降之可能性。



國際海流發電產業發展現況

目前國際上已有多國投入海流發電相關計畫,許多廠商也開始研發設計海流發電機及相關設備,國內亦有廠商投入此一行列。台灣沿岸的黑潮屬於溫鹽環流,為具有環境優勢的潔淨能源,且因不需要燃料供應,是國內少數具規模的自主能源,且黑潮有穩定、高容量因子的特性,用以發電具備作為基載電力的條件。有鑑於此,本文針對全球海流發電產業技術推動現況進行探討,提供我國相關產業發展之參考。

Smart Grid Technology Development Strategy of Taiwan

Taiwan's power system is a large, centralized system with its main sources of power comprising thermal and nuclear (accounting for 94 percent of total generating capacity), and a few hydro and renewable energy sources (RER) (accounting for 4.5 percent of total generating capacity). The system is characterized by large generator units and concentrated loading. Due to the long distances between the power plants and users, all electricity generated is transmitted over power lines and passed through substations before being supplied to users resulting in certain amounts of energy loss (line loss was approximately 4.59 percent in 2013).

美國電力事業與代輸制度介紹及英、美、日代輸制度比較

推動電業自由化為政府既定之方向,台灣行政院已於2015年7月16日通過電業法修正草案,該草案後續將送立法院審議。草案明訂,將電業劃分為「發電業」、「電力網業」及「售電業」3大部分、分別管理。電業法施行前取得電業執照的電業,應在施行日起算5年內,分割為不同公司;如有正當理由未能於期限辦理,得申請展延2次,每次展期不超過2年,最終開放代輸完成「廠網分離」1 。發電業依據「電業法修正草案」第二條之規定,係指設置發電廠以銷售電能之事業。由於發電業並無輸配電網路,未來用戶自由選擇權開放之後,供電給用戶時必須透過電力網業之輸配電網路來傳送電力,並繳納代輸費。代輸費率的設計與定價方式對促進電力市場競爭性與創新技術的導入,具有相當的影響。從推動電業自由化進程可知建立代輸制度使自由申設電廠可與用戶在雙方約定的價格下完成交易,並將電力透過輸配電力網配送予用戶,如此將可增加發電業自主選擇用戶與用戶選擇供電來源空間,是開啟電力自由化引入市場機制的第一步。1965年北美大停電後,電力系統的可靠度受到重視,歷經近40年的電力市場改革歷程,美國的電力事業逐漸從管制型市場,發展出與自由型的重建型市場並存。本文將介紹美國輸配電代輸案例,並彙整過去對於英國配電代輸制度介紹2 以及日本電力事業與代輸制度介紹3 之研究內容,進行英、美、日電力事業環境與代輸制度比較,奠定台灣制定代輸費率架構與推動策略的研究基礎。

台灣離島小型電廠現況與營運策略建議

全世界許多離島由於系統規模小、距離大型電力系統遠,多由個別用戶以柴油機或獨立系統供電,使用碳排放高的化石燃料。由於燃料需遠距運輸,燃料與運輸的高成本導致發電成本高,存在電力供應經濟性課題。台電為配合政府照顧離島居民政策,改善離島民眾生活,依照行政院核准「台電公司接辦台灣省離島電業實施方案」,自民國63年起分三年接辦離島各電業。離島電廠多屬小型燃輕柴油機組,離島小型電廠目前歸屬於業務系統所轄地方區處。而桶盤、花嶼、東吉、東嶼坪、西嶼坪五個尚未被台電公司接管小離島,則由澎湖縣政府、各小離島村辦公室或水電合作社負責其柴油發電機組及海水淡化廠的營運工作。台灣離島供電以柴油發電為主,發電成本遠高於售電收入,目前多由台電公司或地方政府補貼經營,每年金額達新台幣40到50億元。本文將分析台灣離島小型電廠現況、國外小型電廠營運案例與模式,最後提出離島小型電廠營運模式之建議與因應策略。

儲能應用介紹與推動方向建議

電力的儲存通常是利用物理或化學原理,採用不同方式將電力轉換為不同型式的能源,大體可分為機械儲能、熱能儲能、電能儲能、電化學儲能、化學儲能等。儲能系統泛指併接於用戶端或電網,可儲存電網上電力或釋放電能對用戶端或電網供電,並受該電力管理系統控制協同電力系統運作之系統裝置,例如併接於用戶側的家庭儲能裝置或併接於輸配電網路大型儲能裝置。

隨著全球電力消耗持續增加以及環保意識抬頭,加上供電可靠度要求提升、溫室氣體排放減量、人口快速都市化、運輸載具電氣化、電力事業創新商業模式等發展趨勢,各國電力供應系統逐漸向納入分散式電源,擴大再生能朝源利用,提升能源利用效率,以及降低能源密集度的方向發展。面對此發展趨勢,儲能技術可以在電力供應系統中的不同位置提供不同服務,可在電網中應用、貢獻於供熱或供冷網路、配電系統或離網應用。更進一步,儲能系統提供基礎建設在能源系統的供應、輸送、配用與需求端所需服務,提供系統營運商不同工具以平衡系統供應與需求端的變動。

本文介紹紹鉛酸電池、鋰電池、鈉硫電池、液流電池、飛輪儲能等電化學與物理儲電技術發展現況、國際間儲能推動政策措施,並以美國能源部及電力研究所所出版之電力儲存手冊(Electricity Storage Handbook)為基礎介紹儲能主要應用,以英國為例分析用戶端儲能應用於獨立系統發展潛力,最後為台灣推動儲能應用提出方向建議。
