「壅塞管理」( Congestion Management, CM )在電力系統的運轉一直是個嚴重的問題,為了解決這困難的問題,專家學者們提出了各式各樣能夠減輕壅塞問題的方法;本文以等效電流注入法( Equivalent Current Injection, ECI )為基礎,以此電流注入觀念以及線路參數,無須任何的假設,推導出電力潮流追蹤法 ( Power Flow Tracing Method, PFTM )。此法可以得到一靈敏度矩陣(Sensitivity Matrix, SM ) 或稱貢獻度矩陣 (Contribution Matrix, CM ) 推導出每一發電機注入功率與線路潮流量之間的線性關係,以此線性關係推導出本文解決壅塞問題之數學模型。並結合預測-校正式內部點演算法( Predictor-Corrector Interior Point Algorithm, PCIPA ) 用此演算法調度每台發電機之最小變化量以解決電力事故(System Contingency, SC) 發生所產生的壅塞問題。模擬實測在IEEE 30 Bus系統上進行模擬測試,考慮在電力事故方面解決壅塞問題有分為:系統加入重載、系統輸電線跳脫、系統發電機故障、以及多重事故發生。皆可使用本文所提出之方法可以快速得到合理限制內之解,並由測試案例可以驗證本文所提之方法的有效性與可用性。
The “Congestion Management” (CM) always has been an outstanding and major problem in power system operation. To solve this problem, experts compose solutions in a wide variety. This thesis, based on the equivalent current, applies the Equivalent Current Injection (ECI) concept and circuit parameters to derive the Power Flow Tracing Method (PFTM) . By means of this method we can get a Sensitive Matrix (SM), which is also called the Contribution Matrix (CM), to show the linear relationship between the input power and tidal current discharge of each generator set, with the linear relationship we can derive the mathematic model of treating the congestion problem discussed in this thesis. Combining the Predictor-Corrector Interior Point Algorithm (PCIPA), we can manipulate the change of each generator set in the prospective of solving the congestion problem resulting from the system contingency (SC). The thesis performed various simulations for the IEEE 30 Bus system. Regarding the power contingencies, the solutions of the power-congestion problems can be resulted from the following incidents: heavy load addition, transmission line tripped, generator malfunction as well as the multi-contingencies, etc., which can all be solved with solutions within reasonably restricted domains. We can thus verify the effectiveness of the method .
