Flexibility is an inherent property of power system and an important indicator of power system capability to deal with uncertainties.On the basis of the concept of power system flexibility,the optimization method of flexibility resources is proposed in this paper considering the power grid flexibility demand.The classification principles of the flexibility resources are summarized based on the two main characteristics of flexibility demand,namely time scale and direction,and the sets of flexibility resources under different time scales and directions are formulated.According to the characteristics and analysis of flexibility resources,the costs of resources in response to the flexibility demands are determined,and the optimization model for flexibility resources considering the flexibility constraints is proposed.Examples under multi timescales verify the model as an effective complement to traditional optimization process.
