In view of such issues as insufficient flexibility resources and limited regulation capacity in the new energy dominated power system

a kind of storage configuration method for enhancing the active power regulation capability of new energy stations is proposed. Firstly

in response to the multi time scale active power regulation requirements of wind farms

a multi time scale operation scheme for wind storage systems based on dual battery energy storage is proposed. In the proposed operation scheme

the dual battery energy storage will be used to participate such four application scenarios as participating in power generation planning

tracking power generation plans

smoothing wind power fluctuations and responding to system frequency regulation requirements. Then

a dual layer energy storage configuration model taking into account the loss of energy storage lifespan is constructed. Finally

the feasibility and effectiveness of the proposed dual layer energy storage configuration method are verified through the construction of a wind farm in Xinjiang. The results show that the proposed energy storage configuration method can

at the same time of considering energy storage economic performance

improve the active power regulation capability of the wind farm.
