Authors: Gwo-Bin Wu, Chin-Chung Wu, Hao-Ting Tsai, Chun-Yu Chen, Pei-Fang Liang

摘要: 本文以儲能提供輔助服務、電能調度及複合式調度模式作為研究主軸，探討如何透過精進儲能於電網中之功能及使用方式，強化高綠電占比之電力系統運轉調度，進而協助電網在低碳化的進程，達成永續且強韌之運轉。本文首先概覽7個國際先進電力系統之綠能與儲能發展現況，以及未來儲能規劃、電網零碳排之目標。接著針對研究主軸之各項儲能調度功能個別深入研析，透過探討國際電力系統之具體作法，對照國內儲能之應用現況，並以數據模型演示儲能於國內電網之運作，綜合評析精進儲能調度功能之潛在效益與發展性。最後進行盤點比較，歸納國內電力交易機制下取得儲能新型調度功能之可行性。透過統整國際經驗與國內發展趨勢，提供臺灣電力系統低碳化進程之借鏡與參考。

Abatract: This study focuses on the energy storage system (ESS) providing three types of grid services, ancillary service, energy dispatch and joint dispatch service, in the scene of a low-carbon power system. The objective is to obtain the technical improvement of ESS’s deployment to reinforce the grid operation with high renewable energy penetration, which hence facilitates the power network to move toward net-zero emission. An overview of seven advanced international independent system operators (ISOs) is first conducted for outlining the current development and future plan of renewable energy, ESS installation and net-zero target around the globe. The aforementioned grid services are then individually discussed in detailed. Each case is carried out by the review of the ESS deployment of international ISOs’ practice and that of Taiwan's current status. The effectiveness and the feasibility of each service in Taiwan are further analyzed through a data simulation model, and from the aspects of local power trading regulations, respectively. The outcome of this study is expected to add perspectives to the decarbonization of the power grid in Taiwan.
