Title: The influences of power grid structure on self-organized criticality
Abstract: An original view is put forward that,under specific running state,power system self-organized criticality is related to power grid's uniform degree.The uniform degree of power network is characterized by network entropy;then a model to simulate power system self-organized criticality is proposed.Simulations in an IEEE39-bus system with the proposed model show that,under the uniform loading and flow distribution,the higher the grid's uniform degree is,the lower the probability of power cascading failure will be.Furthermore,balancing power grid's uniform degree can effectively prevent large-scale disastrous blackout and reduce the risk of entering power self-organized criticality state.
