针对大容量储能优化设计对优化周期时间长度和时间尺度精细度的要求，本文提出 了一种计及全周期时序特性的微电网源储优化设计方法。该方法通过计及时序特征的聚类算 法从两个维度上削减运行场景的数据量，所得典型场景可保留原始数据中的所有时间顺序信 息。以此为基础，建立包含双时间序列的微电网源储优化设计模型。保序时间序列用于全优 化周期约束，保证模型求解准确性；削减时间序列用于不需要考虑时间顺序的其它约束，降 低模型复杂度。仿真结果表明，在保持相同模型复杂度的情况下，所提方法的源储优化结果 相比于现有其它方法更准确，且方法对大容量储能优化准确性的提升明显，氢储能容量优化 误差降低了 16%以上。

In order to meet the requirements of the optimization cycle time length and time scale precision in the optimization design of large capacity energy storage, a microgrid source and storage optimization method considering full-cycle chronological order characteristics is proposed. In this method, the data amount of the operation scenario is reduced from two dimensions by the clustering algorithm which considering the chronological order characteristics, and the obtained typical scenario can retain the full-cycle chronological order of the raw data. On this basis, a microgrid source and storage optimization model containing two time series is established. The sequencepreserving time series is used for the whole optimization cycle constraint to ensure the accuracy of model solving. The reduced time series is used for other constraints that do not require consideration of chronological order, so the complexity of the model can be reduced. The simulation results show that the proposed method is more accurate than other existing methods in the case of maintaining the same model complexity. The proposed method significantly improves the optimization accuracy of large capacity energy storage, and the optimization error of hydrogen energy storage capacity is reduced by more than 16%.
