Economic Dispatch of Wind Integrated Power System Based on Operation Risk Constraints

The large-scale wind power incorporation increases the uncertainty of the power grid. In this paper, we propose a new stochastic optimization method to eliminate it. The entropy risk value (EVaR) is used to describe the safety margin of the power system for limiting the safety margin to the power system security risk constraint. Finally, we use matlab to validate the validity of the model and the effectiveness of the method by numerical simulation of IEEE 30 nodes, and compare the scheduling results under different security margin and confidence level.
