| 摘要: |
| 针对风电集群联合共享储能系统的协调控制和收益分配问题，提出基于预测误差分配原则的运行控制策略。首先，设计共享储能商业运行模式，建立储能变寿命与充放电模型。考虑政策补贴和季节性温度对储能定价和容量配置影响，建立多风场时空相关特性的风群联合大容量共享储能参与能量/调频市场的容量规划模型。通过所提策略计算风储联合系统的最优储能容量配置，分析季节性风况对储能配置的差异性。结果表明，在无储能购电补贴时，所提商业模式也能获得稳定盈利，并同时满足风电集群并网要求，控制弃风率在5%以内。基于误差分配的方法能够平衡各风电场收益，考虑季节性温度使储能实际收益提升约3.6%。同时夏冬季储能配置呈现双反比现象，所提方法为发电侧共享储能规模化应用提供了参考。 |

| Abstract: |
| Aiming at coordination control and revenue distribution for a wind power cluster joint shared energy storage system, an operational control strategy based on the principle of prediction error distribution is proposed. A commercial operation mode of shared energy storage is designed, and the variable life and charge-discharge of energy storage is established. Considering the influence of policy subsidies and seasonal temperature on energy storage pricing and capacity allocation, a capacity planning model of wind groups participating in the energy/frequency modulation market with large-capacity shared energy storage is established. Using the proposed strategy, the optimal energy storage capacity allocation of the wind-storage combined system is calculated, and the difference of seasonal wind conditions on energy storage allocation is analyzed through examples. The results show that the proposed business model can obtain stable profits without subsidies, and meet the requirements of wind power cluster grid connection, and control the wind abandonment rate within 5%; this method, based on the principle of error distribution, can balance the benefits of each wind farm, and considering seasonal factors, the actual benefits of energy storage can be increased by about 3.6%, and its configuration presents a double inverse ratio phenomenon, which provides a reference for the large-scale application of shared energy storage on the power generation side.
