Optimal scheduling for power system considering wind power Ramping uncertainty

The increasing uncertainty of wind power has a more and more serious impact on system safety. Therefore, the problem of optimal dispatch for power system considering the uncertainty of wind power ramping is studied. Firstly, a stochastic model of wind power is established based on the scenario analysis method, and the wind power output of a typical scenario is predicted, and then its ramping is identified, and the predicted results of wind power ramping are obtained. Secondly, based on the prediction of wind power ramping, an economic ramp scheduling model for power system containing PtG equipment is proposed. Finally, the validity and correctness of the model proposed in this paper are verified by IEEE33 node system.
