A SUPPRESSION MECHANISM OF CASCADING FAULT IN THE INTERDEPENDENT COUPLING SMART GRID

The smart grid which decouples the power network and the communication network will cause a revolution in the traditional power grid. Equipment such as routers in the communication network is in need of power supply, and the dispatching of the power network and intelligent decision requires communication network to transfer and control. This dependency relationship will lead to cascading fault. An interdependent coupling network tends to cascade fault because of the heterogeneous coupling. In order to study the suppression mechanism of coupling network cascading fault. we adopt the pairwise schema and propose a heuristic dual cover dual redundancy algorithm based on an independent network model. Through the extensive simulation results, we analyze and evaluate the performance of our suppression algorithm, and the results demonstrate the effectiveness, The pairwise schema proposed in this article can he easily extended to multilayer network by subsequent researchers, Furthermore, our models may he slightly modified, and can be widely applied to many practical networks.
