為達成我國經濟部能源局2025年再生能源佔20%之目標，於2021年電力交易平台正式上線，為併網之頻率相關問題提出了一系列解決方案；而台灣的下一步，便是加速提升我國之主要再生能源-太陽能與風力之滲透率，在不更動既有饋線設備的情形下，加入更多的太陽能併網。
故本研究的主要貢獻在於針對擴增太陽能所搭配之儲能，在滿足我國現行規範之太陽能擴增與儲能系統特定比例之下，設計一套兼具保護饋線與能源套利功能之BESS充放電控制策略，其控制策略將透過太陽能發電量百分比做為基礎，配合多元線性迴歸以溫度、濕度進行每小時發電量預測，並加入控制策略當中進行充電指令的調整，最後透過matlab程式帶入實際的案場發電量進行達三十天的模擬，根據其結果顯示，本論文所提出之控制策略適用於我國太陽能結合儲能之現行規範。

When facing the crisis of energy and global warning, most countries increasing the investment to raising the renewable energy. As renewable energy raises rapidly, the impact to power Grid should not be neglect. In order to solve this problem, the renewable energy integrate with the battery energy storage system, BESS, becomes the most useful solution. The BESS, which couple with PCS and battery, can provide multi-service through their trait of quick response. It is the reason why that IRENA take BESS as the first place to achieve the NetZero project at 2050.
In Taiwan, the government planned to increase the renewable energy rate at 20% of the total power generation. To achieve this target, on one hand, our government set the online power trading to relieve the frequency impact due to the renewable energy joined. On the other hand, the government’s next target is to raise the penetration both of wind and PV through increase the installed capacity without new power line.
In this paper, the BESS control strategy is proposed to meet the government’s need with specific ratio of PV and BESS. The strategy takes the ratio of available PV generation and PV capacity as base and support with PV generation forecast which through multi-linear regression by temperature and humidity to achieve both of power line protection and arbitrage in matlab. The simulation shows that the strategy is suitable for the actual policy.
