论文摘要
我们使用复杂网络的框架在印度电力传输网络上介绍了该研究，并量化了其结构特性。为此，我们使用其两条最普遍的电力线建立了印度电力网格基础的网络结构。我们构建了指数网络的等效模型，并研究了其结构变化，其中两个参数的变化与冗余和死胡同有关。然后，我们通过使用链接失败模型来改变这两个参数来分析其针对级联故障的稳定性。这有助于深入了解网络拓扑与其稳定性的关系，并指示这些参数的最佳选择如何导致功率网格结构具有最小失败的链接。我们采用相同的模型来研究印度电网对此类故障的鲁棒性。在这种情况下，我们发现，当连接到发电机失败的链接失败时，它会导致级联在网格中传播，直到将其分成两个单独的发电机和消费者群体，其中三分之一以上是其节点nonodes nonodectiona
We present the study on the Indian power transmission network using the framework of a complex network and quantify its structural properties. For this, we build the network structure underlying the Indian power grid, using two of its most prevalent power lines. We construct an equivalent model of an exponential network and study its structural changes with changes in two parameters related to redundancy and dead-ends. Then we analyze its stability against cascading failures by varying these two parameters using the link failure model. This helps to gain insight into the relation of network topology to its stability, and indicates how the optimum choice of these parameters can result in a power grid structure with minimum failed links. We apply the same model to study the robustness of the Indian power grid against such failures. In this case, we find that when a link connected to a generator fails, it results in a cascade that spreads in the grid until it is split into two separate stable clusters of generators and consumers, with over one-third of its nodes nonfunctiona
