| 摘要: |
| 复合多种类型储能装置是储能用于风电波动平抑的主要发展方向之一。针对复合超级电容器和多种介质蓄电池为例，研究其储能容量优化配置方法。由于风电出力具有非平稳性，因此首先采用经验模态分解(EMD)分割平抑任务，然后利用互补平抑实现储能装置优势互补，最后综合考虑风电平抑度、平抑方案经济性和储能装置寿命三方面因素，建立以费用效率(CE)为目标函数，用雨流计数法统计寿命折损的混合储能定容优化模型。利用所建模型分析了适当允许过充过放是否能够提高平抑方案的经济性和平抑能力。验证了多种介质蓄电池在合理的配置方案下联合超级电容器平抑波动，相较单种介质蓄电池能增加单位投资的平抑能力。 |

| Abstract: |
| Composite energy storage device is the future development direction of energy storage in stabilizing the wind power fluctuations. This paper takes composite super capacitor and different battery media for example and studies the optimal configuration method of energy storage capacity. Considering the nonstationarity of the wind power, the task of stabilization using Empirical Mode Decomposition (EMD) is split. Then, complementary stabilization is used to realize the energy storage of mutual advantage complement and improve the smooth degree. At last, considering economics, smooth and battery life, the model of capacity determination of hybrid energy storage is built. In this model, cost efficiency is the objective function and rain flow counting method is used to calculate the loss of battery life. This model analyzes whether it can improve the economic efficiency and smooth capacity of the scheme or not if allowing to overcharge and over discharge appropriately. It is verified that under reasonable cooperation scheme composite different battery media can increase the stabilizing ability of unit investment compared to the single battery medium. |
