| With the progress of time, the relationship between various types of infrastructures have become increasingly more closer. The power system developed to the direction of the smart grid, which means the relationship between power system and the energy transport systems, communication systems, control systems increasingly more closer. This coupled with the dependence becoming increasingly closely, while accompanied by the emergence of such as: does the stability of the whole system is reliable, what impact each other mutual coupling between systems, and so on.Based on the theory of complex systems and complex network knowledge, from the individual to the system, from the isolated network to the interdependent networks, this paper discusses the application of complex network theory in power grid, and influence of interdependent networks theory in the power grid and communication network. And give network robustness for a more detailed exposition. Based on network topology structural of IEEE118bus system and China Southern Power Grid153-node system and power system knowledge, this paper analysis the complex of power system and establish interdependent networks model. Using actual and reasonable characteristic of the power grid and DC method of power flow calculation, to building the indicators for the modeling’s evaluation, and then set the fault strategy of simulation.Contrast whether to consider the influence of communication network efficiencv on the power grid, and found communication efficiency drop will product packet redundancy and slow down control regulation. Thereby make some of the original can be controlled within the safety threshold trend overload, thus affect robustness of the power grid. Thus proved the existence of influence between interdependent networks. And to create a parameter set according to the model, to a certain extent on the quantitative results of the influence of the communication network of the power grid. |
