通信光缆故障对电力网连锁故障的影响
Impact of Failure of Communication Optical Cable on Cascading Failures of Power Grid
摘要
Abstract
Research on the cascading failures is important to dealing with blackouts,but the impact of failures of communication optical cable is seldom considered in conventional research on cascading failures in the power system.From the perspective of the edge of information network,a model for the failures of communication optical cable with an impact on the cascading failures of the power grid is built based on DC power flow model.The impact on cascading failures of the power grid with random failures of communication optical cable and different topologies of information network are studied with an IEEE 30-bus system as an example.Simulation results show that owing to the introduction of the information network,the power system is becoming increasingly vulnerable,leading to greater risk of blackouts.With the increase in failure scale of the communication optical cable in the information network,the impact strength of failures of communication optical cable on the cascading failures of the power grid changes from strong to weak till stability.Meanwhile,the influence of the topology of information network on the cascading failures of the power grid is manifest,and a broader degree distribution of information network increases the vulnerability of power grid.This shows that,in regular networks,the greater the degree of information vertex is,the weaker the impact of the failures of communication optical cable on the cascading failures of the power grid will be.
