Abstract
Due to wind resources distribution characteristics and current situation of power grid, wind power is mainly large-scaled and centralized developed in China. In order to meet the security requirements of power system under this circumstance, a real-time security constrained dispatch method considering the impact of wind power uncertainty on N-1 line contingency safety is proposed. Key N-1 line contingency security constraints are identified by sensitivity analysis and added into dispatching model. Robust optimization approach is employed to solve this optimal problem. Simulation results of the IEEE-30 nodes power system validated the rationality and feasibility of the proposed method.
