Based on the uncertainty scenarios considering temporal dependence of wind power prediction errors, the energy storage system is applied in both energy shifting pattern and plan following pattern. A multi-pattern coordinated optimization model for the wind power and energy storage combined system is proposed. Meanwhile, in view of the large-scale mixed-integer programming problem in the combined operation of wind power and energy storage system, the shifting ratio of energy storage capacity is proposed to develop the bi-level iterative optimization algorithm for fast sloving the model. The shifting ratio of energy storage capacity is further applied to quantitatively evaluate the capacity allocation. The results of the simulation based on actual data show that the optimal operation pattern of the wind power and energy storage system is influenced by factors including the selling price, penalty price and stochastic characteristics of wind power. And the model proposed is able to realize rational allocation and highly efficient utilization of the limited energy storage among different scenarios, providing important information for research on wind power and energy storage combined system operation and coordinated dispatch with power grids.
