| 摘要: |
| 考虑到风电并网波动性和不确定性造成大量弃风的弊端，为了提高风电场的综合效益，提出基于退役电池阈值设定和分级控制的弃风消纳模式以降低储能成本。考虑到退役电池状态的不一致性会导致整体储能的效率低下，控制效果很难达到预期的情况，对退役电池充放电深度与循环寿命之间的关系进行分析，利用分段概率分布函数设定理想退役电池的充放电阈值范围；为了延长退役电池的使用寿命，利用分级控制策略实现其分级实时动态切换储能功能。对所提策略进行算例分析，结果表明分级控制策略相较于整体控制策略具有更好的经济性，促进了弃风消纳。 |

| Abstract: |
| Considering the disadvantages of large-scale curtailed wind caused by the volatility and uncertainty of grid-connected wind power, in order to improve the comprehensive benefits of wind farms, a curtailed wind consumption mode based on threshold setting and hierarchical control of retired batteries is proposed to reduce the costs of energy storage. Considering that the inconsistent state of retired batteries will lead to low efficiency of the overall energy storage and the control effect is difficult to reach the expected situation, the relationship between the depth of charging and discharging of retired battery and its cycle life is analyzed, and the segmental probability distribution function is used to set the charging and discharging threshold ranges of the ideal retired battery. In order to prolong the service life of retired batteries, the hierarchical control strategy is used to realize the real-time dynamic switching energy storage function. The proposed strategy is simulated and analyzed, and the results show that the hierarchical control strategy is more economical than the overall control strategy and promotes the curtailed wind consumption. |
| Key words: retired batteries curtailed wind consumption depth of charging and discharging threshold setting hierarchical control energy storage system |
