DLR based Preventive Dispatch for Mitigating Wind Power Uncertainty Induced Line Overloads

Wind energy has been widely integrated into power systems because of its clean and sustainable characteristics. Meanwhile, the uncertainty of wind power also introduces some new risks into power systems, such as line overloads. And the dynamic line rating (DLR) is recognized as a good method to mitigate the line overloads caused by wind power uncertainty and improve the integration of wind energy. To address the risk of wind power uncertainty, we in this paper propose a trilevel preventive model considering the DLR to mitigate line overloads caused by wind power uncertainty. And we also present a Bender like decomposition method to solve the tri-level optimization problem. The simulation results on the IEEE 118-bus system prove that the effectiveness of the proposed model.
