摘要
基于简化的二阶耦合振子模型,考虑网络的权重特征,构建了双层耦合振子电网的物理模型,并从能量流的角度分析了电网面向不同属性的输电线失效时的网络弹性能力.以一个2层电网为研究对象进行数值模拟,结果表明,异质传输线失效时,网络弹性能力较弱;同质传输线失效时,网络弹性能力较强.
Based on second-order coupled oscillatory model,considering the weight of the network,this paper proposes a duplex power network.From the view point of power flow,we study the resilience of the proposed duplex power network face to the deletion of transmission line with different characteristic.A small-size duplex power net-work is taken as an example for numerical simulation.Simulation results indicate that the power network is vulnera-ble under the deletion of heterogeneous transmission lines between layers.However,the power network has better re-silient ability under the deletion of homogeneous lines.
