| 摘要: |
| 为在基于复杂网络理论的连锁故障模型中计及校正控制的影响，提出基于潮流追踪的按比例削减负荷与有功网损最小的最优潮流模型相结合的校正控制方法。该方法采用潮流追踪技术，在节点故障后形成的孤岛子系统中，根据转移负荷确定负荷削减区域，并进行削减负荷。基于复杂网络理论提出计及该校正控制方法的电力系统连锁故障模型。该模型克服了只在拓扑层面对连锁故障描述的缺陷，能够反映负荷分布的变化对连锁故障的影响。通过对IEEE 30节点系统的仿真计算验证了所提校正控制措施的可行性和有效性。仿真结果表明，所提校正控制措施可在负荷分布均匀时减小连锁故障发生的规模。 |

| Abstract: |
| In order to consider the effect of corrective control on the cascading failure model based on complex network theory，a corrective control method combining the proportional load-shedding based on the power flow tracking with the optimal power flow model based on the minimum active power loss is proposed，which adopts the power flow tracking technology to determine the load-shedding area according to the loads to be transferred in the islanded subsystem generated after the node failure and sheds the corresponding loads. With the consideration of corrective control method，a power system cascading failure model based on the complex network theory is proposed，which describes the cascading failure beyond the topology level to reflect the impact of load distribution variation on the cascading failure. The simulation for IEEE 30-bus system verifies the feasibility and effectiveness of the proposed method，and the simulative results show that，the scale of cascading failure can be reduced when the loads are uniformly distributed. |
