再生能源已逐漸往高佔比的方向發展，同時，電力系統的慣量隨著再生能源增加而下降，因此系統頻率穩定性的問題也浮現出來，並且成為未來發展成功與否關鍵因素。
本文分析儲能系統參與增強型輔助服務於再生能源佔比0%～50%情境，並以太陽光電為主；首先，以台灣夏季電力年尖峰負載資訊，套入連續二次規劃法求得不同再生能源佔比下，電能轉移排程規劃之儲能系統充放電量。其次，使用IEEE 39Bus為電網架構，利用PSS®E電網分析軟體探討電能轉移後，儲能系統剩餘功率是否可應對電網中最大機組發生事故衝擊，並探討不同斜率之頻率下垂工作曲線，對於初始頻率變化率與頻率最低點之影響。
結果顯示在最為極端情況，此時單日再生能源平均佔比30%與瞬間最高佔比達62.1%，本提出方法可使系統頻率響應與儲能系統的功率輸出得到很好的改善與提升系統穩定性。

Renewable energy is gradually trending towards higher proportions, and simultaneously, the inertia of the power system decreases with the increasing integration of renewable energy. Consequently, the issue of system frequency stability has become a critical factor in the success of future developments.
This paper analyzes the involvement of energy storage systems in enhanced ancillary services with renewable energy penetration ranging from 0% to 50%, primarily focusing on solar photovoltaic energy. Firstly, using summer power load data from Taiwan, sequential quadratic programming is employed to determine the energy transfer scheduling of the storage system for different proportions of renewable energy. Secondly, utilizing the IEEE 39Bus as the power system framework and the PSS®E power system analysis software, the paper investigates whether the remaining power in the storage system can effectively handle the impact of the largest generating unit in the power grid after energy transfer. Additionally, the study explores the influence of different slope frequency droop curves on the initial frequency change rate and the frequency minimum point.
The results indicate that, even in the most extreme scenario, with a single day's average renewable energy share of 30% and an instantaneous peak share reaching 62.1%, the proposed method significantly improves the system's frequency response and enhances overall system stability.
