摘要
能源是經濟發展與民生不可欠缺的要素,臺灣能源幾乎全仰賴進口,因此發展具自主性的綠色新能源將是臺灣首要關注的焦點;由於新能源中的太陽能及風力發電都受天氣限制,隨著新能源在電網中比例提高,再生能源的不穩定性及間歇性問題漸凸顯出來,造成能源供應不穩定。而電網系統引入儲能環節後,可以有效地實現需求側管理,達到削峰填谷(晚上用電量需求較低,可將多餘的電力移到白天使用)或是冬電夏用的作用,以平滑負荷。不僅可以更有效地利用電力設備,降低供電成本,還可以促進可再生能源的應用,也可作為提高運行穩定性、調整頻率與補償負荷波動的一種手段。因此,本文將著墨於各儲能技術之發展現況、儲能系統安裝成本與系統價格,及未來各技術研發重點與規劃…等,期望能給相關單位參考,營造有助於再生能源及電網儲能產業之發展環境;也期望政府搭配相關技術輔導與獎勵措施,帶動再生能源與儲能技術之發展,並促進資本累積、新興產業發展與創造就業機會,最終將有利於臺灣經濟成長。

Energy is indispensable elements for economic development and civilian. Taiwan is relies heavily on imported energy resources. Therefore, developing self-independent renewable energy resources will be the primary focus for Taiwan. For some renewable energy sources, such as solar energy and wind energy, the applications are limited by weather conditions. With the increasing proportion of renewable energy sources in the grid, the instability and intermittency of renewable sources causing unstable energy supply are underscored. Introducing energy storage systems into electric grid will enhance the demand-side manage efficiency and eliminate the difference between peak and valley due to electric power consumption variation in days and nights. The energy storage system provides efficient utilization of the electric equipment, enhances the cost reduction in power supply, and promotes the applications of renewable energy sources. It also can be considered as a means of improving overall power quality and reliability, adjusting frequency and compensating for load fluctuations. This paper is focused on the development and market profile of energy storage technologies on current status. Applicable overview, international energy storage installation costs and system prices, R&D focus and planning of all energy storage technologies are also introduced in this article. We hope that this paper will be a reference to the related units for the future energy storage industry in Taiwan. The government has to create an environment which is beneficial to the development of renewable energy and grid energy storage system with technical guidance and industrial encouragement. The ultimate goals for the above-mentioned issues are to improve the capital accumulation, the development of new industries and the increasing employment opportunities. This is eventually beneficial to the economic growth in Taiwan.
