中文摘要 | 本文應用蓄電池儲能系統於多機電力系統中來增加其穩定度。蓄電池儲能系統之動態模型由BES等效電路中推導而得,BES於多機系統中之裝設位置將由特徵結構分析決定,參數以特徵值指定法求得。所推得之BES模型可供日後相關研究使用,而設計方法可為將來設置蓄電池儲能系統時採行評估。 推導所得BES模型為調制實功率模型,降低模型之複雜度,並增進對BES行為之觀察,多機電力系統模型由參考座標軸理論建立,模擬結果顯示模型行為符合電力系統動態,可有效改善穩定度。而特徵值分析結果顯示:分散式裝置小容量BES,除可就近發揮BES於負載均化、電壓調整等功能外,對系統之穩定度有較佳之助益。 |
英文摘要 | This paper applies battery energy storage system (BES) in multi-machine power system to improve stability. The dynamic model of battery energy storage system is derived from BES equivalent circuit and operation theory of converter base on the active power modulation mode. The installing location of BES for multi-machine power system is decided by eigenstructure analysis. The parameters are determined by using pole assignment. The BESS model presented in this project supports the future research, and the designed scheme will be used to evaluate the installing effect of battery energy storage system. BES dynamic model is an active power modulation model, which reduces the complexity of simultaneous active and reactive power modulation model and improve the observability in BES behavior. Multi-machine system is derived base on reference frame theory. The eigenvalue analysis and simulation results show that the BES can damp the low frequency oscillation of multi-machine power system and improve dynamic stability. The eigenvalue analysis results shown that small size decentralized BES location not only better for load-leveling and voltage regulation but also more stable than the same rate and capacity packed location. The performance of BES with auxiliary controller designed under heavy load is better than which designed under light load when the operating point of power system is varied. Both small signal and large disturbance time domain simulation of the studied system show that BES with auxiliary controller can improve system stability. |
