近幾年，隨著各國再生能源滲透率逐步提升，無可避免要面臨其間歇性帶來的相關問題，再加上由於系統整體的慣量減少，因此對突發事故的響應能力相對也會變差。隨著被替代的傳統機組越來越多，勢必會需要儲能系統的投入以因應高占比再生能源對電網所帶來的衝擊，並協助系統穩定且安全的運轉。

本論文提出一套方法可以充分運用電池儲能系統優越的特性來彌補再生能源對系統帶來的衝擊、提高再生能源占比，同時還能讓儲能系統實現以下幾項特點：(1)將儲能系統加入經濟調度中，並利用混合整數線性規劃找出24小時的經濟調度，使儲能系統進行能源套利的服務；(2)透過在經濟調度的備轉容量限制式中加入儲能系統並修改其SOC上下限的方式，讓儲能系統可以參與儲備，在發生事故時隨時滿載充放電以支援電網直到發電機開啟或關閉；(3)根據儲能系統「在充電時可以快速切離充電狀態」的特性，使其在電網較為脆弱時保持一定的充電量，若發生事故則可以透過減少負載的方式以維持供需平衡，為電網提供發電機跳機事故的保護，並透過電力系統分析軟體PSS®E找出每個小時儲能系統最低需要多少充電量以符合最大發電機組跳脫時頻率最低點之安全約束條件，最後，再將其加入限制式中重新排程，以此找出經濟且安全的調度規劃。

In recent years, with the gradual increase in the penetration rate of renewable energy in various countries, it is inevitable to face related problems caused by its intermittent. In addition, due to the reduction of the inertia of the system, the response-ability to emergencies is relatively poor. As more and more traditional units are replaced, the participation of energy storage systems is bound to be required to cope with the impact of the high proportion of renewable energy on the power grid, and to assist in the stable and safe operation of the system.

This paper proposes a set of methods that can make good use of the superior characteristics of battery energy storage systems. While coping with the system impact caused by renewable energy and increasing the proportion of renewable energy, it can also let the energy storage systems achieve the following characteristics: (1) By adding the energy storage system into economic dispatch and using mixed-integer linear programming to find out the 24-hour economic dispatch of the grid, let it participate energy arbitrage. (2) By adding the energy storage system to the spinning reserve constraints of economic dispatch and modifying the upper and lower limits of its SOC, let the energy storage system participate in the spinning reserve, so that it can support the grid by rated charging and discharging at any time when the contingency occurs until the generator is turned on or turned off. (3) According to the characteristics, "Can quickly cutting off the state of charge when it is charging", the energy storage system can keep a certain amount of charge when the power grid is relatively fragile. It can maintain a balance by reducing the load to provide the protection of generator trip contingency for the grid. The power system analysis software PSS®E is used to find out the minimum charging amount required by the energy storage system at each time point to meet the safety constraints of the nodal frequency when the maximum generator trips. Finally, add into the constraint for rescheduling to find out the most economical and safe dispatch for the energy storage system and generators.
