透過網路效率探討電網連鎖性失效行為 / Exploring the cascading failure of power grids by network efficiency

現實社會中,有時會發生大規模的停電事件,一經調查後才瞭解,只是因為一根電纜線、一根高壓電塔或是一個變電站故障導致,令人好奇電力系統的運作模式。因此藉由拓蹼網路的特性去研究電力系統的安全性及穩定性,一直受到人們的關注和討論。本篇論文利用動態負載去模擬現實中的電流,並藉由連鎖性失效的攻擊策略對於網路效率的影響,去判斷其網路的脆弱性分析。

本論文利用網路效率的(efficiency)影響來作為網路脆弱性(vulnerability)的分析,藉由在靜態負載中連鎖性失效的模型(static load cascading failure model)和動態負載中連鎖性失效的模型(dynamic load cascading failure model)來判斷及討論,其中動態負載為不同發電量及消耗量的狀況,藉此觀察台灣的電力網路系統在狀況下的結果。

此外以攻擊方來思考,單一攻擊、多重攻擊和策略性的多重攻擊的狀況底下,網路效率的變化,並將此運用在台灣電力網路系統上,發現台灣電力網路相當脆弱。 / In the real world, sometimes there will be black out (power shortage) happening in large scale areas. After investigating, we found out that it was cause by either a broken transmission line, a high-voltage tower or a substation. We are very interesting to know how the operation scheme of power system works. Therefore, we study the safety and the stability in power system by the characteristics of topology network. This subject is always concerned and discussed by the society. The thesis use dynamic load to simulate current in real world. We foc us effect on network efficiency by the strategy of cascading failure, analyze the vulnerability of network.
The thesis use the variation of network efficiency as index to analyze network. According to determining and discussing by static load cascading failure model and dynamic load cascading failure model, dynamic load is the situation in different amount of generating and consumption of electrical energy. We used the data to observe the result of Taiwan power system under the situation.
In addition to, changing of internet efficiency by single attack, multi-attack and strategic multi-attack in attacker method of thinking. We found that Taiwan power system is weak after we used the statistics on it.
