Applications of forecasting based dynamic p-cycle reconfiguration under reliable optical network in smart grid

There is a significant motivation to increase restoration speed of electric power communication network by using mesh-based schemes, because they can always take less time to achieve network convergence. However, on the other side, it often involves large amount of extra overhead and thus consumes more controlling bandwidth. In order to design efficient survivable transport network, we propose a forecasting based p-cycle (FDP) to adapt to the rapid development of information communication technology network and the communication infrastructure of further smart grid. The proposed approach has the immediate benefit of providing natural reconfiguration under dynamic service requirement by investigating the statistical properties of power grid. Interface of GMPLS control plane and been extended for the proposed approach, and several reconfiguration approach is evaluated with the support of distributed pre-configuration scheme using GMPLS and new LSA type in OSPF-TE to realize this scheme. We also analyze the performance of decentralized control algorithm over information networks whose topology matches that of underlying power network and use analytical approach to determine whether the proposed method works well under different reconfiguration strategies. Additionally, various classical p-cycles enumeration algorithms together with distributed configuration protocol from previous work are evaluated under FDP approach and the efficiency protection resource utilization is examined.
