Abstract (EN): The increasing penetration of uncertain generation from renewable resources poses a challenge for keeping flexibility of power system. Therefore, in order to deal with the condition of insufficient flexibility, a day-ahead modified dispatching model considering the flexibility of power system is proposed. In this modified model, the flexibility is represented by up-regulated flexibility coefficient and down-regulated flexibility coefficient, and these parameters will be used to construct the wind power deviation cost in the objective function which is used to increase the regulated capacity of power system. In the case study, two wind power nodes in the IEEE 30-bus system are connected to two actual wind power farms in Hebei province respectively to verify the validity of the modified model. Finally, Simulation results show that, compared with conventional dispatching models, the modified dispatching model can not only reduce the economic cost, but also increase available regulated capacity to enhance the flexibility of power system.
