中文摘要
本篇論文透過最佳化方式,找出電力系統中,電力線中斷位置。 藉由向量量測裝置,可以得知每個匯流排上之電壓相量,進一步從電壓相量及電力線上的阻抗,更能夠得知每個匯流排上的功率大小,若進一步的加以推導,便能將整個問題描述成一個最佳化的形式,透過最佳化來解決此問題,將不用再針對不同斷線數量,開發不同演算法,能夠有效提升整體效率,再選以適當之演算法,更能彰顯其準確度。
本文選用化學反應最佳化,作為解此問題的演算法,此演算法適用於任一型式最佳化問題,並提供多個參數,供使用者依不同類型問題加以設定,使演算法發揮最好效能,此外,由於本文所要解之問題,不同於常見之最佳化問題,屬於NP-hard類型的最佳化問題,並且本文之問題須在離散的集合內做搜尋,然而,化學反應最佳化卻能夠有效解決上述兩個難題,
能夠於最短時間,達到相當高的準確度。
Abstract
In this thesis, we consider to identify multiple power line outages via phasor measurement unit. For this purpose, we use the linear DC power flow model and formulate the power line outage identification problem as a combinatorial optimization problem.
Therefore, the optimal solutions, i.e., power line outages, can be found by the exhaustive search. However, as a network expands with more buses, the search space grows exponentially with the number of line outages. As a result, it becomes inviable to perform an exhaustive search.To tackle this problem, we exploit the chemical reaction optimization (CRO) algorithm, which has applied to many combinatorial optimization problems, to solve the power line outage identification problem. The algorithm is tested using the IEEE 118-bus system.Simulation results demonstrate that the percentage of correctly identified line outages achieved by the CRO algorithm exhibit comparable performance to those by the exhaustive search.
