再生能源結合儲能系統之應用
Renewable energy combined with energy storage system
摘要
再生能源併入電網之後，隨著再生能源建置量逐漸增加，大量再生能源併入電網中，而形成分散式的電能結構，因此需要探討電力系統併網的穩定度分析。而利用儲能系統，可彌補再生能源發電之間歇性，增加電網中調度再生能源的彈性與電網強韌性。隨著儲能系統的技術發展越來越先進，儲能系統的充放電，可作為穩定電力傳輸的重要工具。常見的電池芯化學系統可分為三種類型：鉛酸電池、磷酸鋰鐵電池和鋰三元電池，其中以鋰離子電池為主要使用種類。 本報告針對再生能源結合儲能系統應用於電力調控進行研究。對於再生能源特性、燃料電池，以及儲能系統之應用進行架構探討。將儲能系統的充放電性能運用於削峰填谷、負載轉移、頻率控制與電力調度等用途。本報告並對燃料電池結合功率調節器與控制器，以實現電能自主調控技術與測試波形等技術，進行研究分析。 本報告首先對於再生能源系統併入電網進行架構上的運用說明。進而對靜態同步虛功率補償器及儲能系統之運用說明其功能。最後對併網時的電網安全，避免線路或設備過載，以及電力品質進行規劃設計。

After the integration of renewable energy into the power grid, with the gradual increase in renewable energy installations, a large amount of renewable energy is integrated into the grid, forming a decentralized power structure. Therefore, it is necessary to explore the stability analysis of power system integration. The use of energy storage systems can compensate for the intermittency of renewable energy generation, increasing the flexibility and resilience of the power grid in managing renewable energy. With the advancement of energy storage system technologies, the charging and discharging of energy storage systems can serve as important tools for stabilizing power transmission. Common battery chemistries can be classified into three types: lead-acid batteries, lithium iron phosphate batteries, and lithium-ion batteries, with lithium-ion batteries being the primary type used. This report focuses on the application of renewable energy combined with energy storage systems in power regulation. It discusses the characteristics of renewable energy, fuel cells, and the application of energy storage systems. The report explores the use of energy storage system's charging and discharging performance for peak shaving, load shifting, frequency control, and power dispatch. It also investigates the integration of fuel cells with power regulators and controllers to achieve autonomous power control technology and waveform testing. The report first provides an overview of the architectural utilization of renewable energy systems integrated into the power grid. It then explains the functions of static synchronous compensators and energy storage systems. Lastly, it addresses grid safety during integration to prevent overload on lines or equipment and plans the design for power quality.
