Title: Trends and Opportunities of Energy Storage in Renewable Energy Integration

摘要: 低碳能源轉型已成為全球能源發展方向，隨著再生能源裝置量與滲透率提升，間歇性的再生能源(如太陽光電、風力發電)對電網衝擊風險提高。為解決大量再生能源併網所造成的負面影響，儲能技術成為可能的解決方案之一。近年來，大型再生能源電廠配置儲能系統逐漸成為趨勢。因此，本研究欲透過個案研究方法與次級資料分析，觀察再生能源與儲能發展較快速之國家地區，以美國、日本、英國等地區共4個案例作為研究標的，解析上述個案之儲能運用模式。試圖解答儲能於再生能源整合運用之功能效益，同時歸納分析促使大型再生能源電廠配置儲能之要素。整體而言，驅動再生能源與儲能整合的因素，一是法規範層面的要求，另一方面則為經濟層面誘因，使再生能源成為可調度資源、參與不同電力服務多元化、極大化收益。本研究認為伴隨我國電力市場改革與交易自由化，新的電力市場機制與能源交易環境可為儲能與再生能源整合創新商業模式帶來契機，進而衍生整體社會最具經濟效益，且安全可靠之電力供給模式。

Abatract: Increased use of renewable energy (such as solar photovoltaic and wind power generation) raise the risk of grid stability. To solve the impact of renewable energy on power grid, energy storage system is one of the possible solutions. Growth of co-located energy storage, such as solar-plus-storage and windplus-storage, became a trend in the recent years. The study aimed to study and analyze the applications of those energy storage systems in combination with renewables, to find out the patterns of co-located energy storages and something we can learn from. Based on case study, the present research also attempted to explore the driving force behind co-located energy storage. This case-base study chose four cases in advanced countries, including United State, U. K. and Japan. The study found that, the driving force could mainly defined by two aspects. One is regulation, and the other one is economic incentive. Since Taiwan is on the way of electricity market reform, there will be more opportunity for innovative energy storage business models, and transform to a flexible and reliable power system.
