摘要
为解决目前储能规划中场景划分不够精确及模型适用范围有限的问题,提出了基于负荷场景多层聚类的储能精细化规划方法。首先,提出了基于关联分析与聚类的负荷时空耦合特性分析方法及考虑负荷时空特性的负荷场景多层聚类方法。其次,面向典型负荷场景,构建了综合考虑碳排放、全周期成本、弃风弃光惩罚及储能和分布式电源协同的储能精细化规划模型。最后,选取某地实际配电网开展算例分析,得到了不同负荷场景下储能与分布式电源的最优协同配置方案,验证了所提模型与方法的可行性与有效性。
To address the current issues of insufficient precision in scenario division and limited applicability of models in energy storage planning,the paper proposes a method for refined energy storage planning based on multi-layer clustering of load scenarios.Firstly,an analysis method is introduced that considers the spatiotemporal cou⁃pling characteristics of load using association analysis and clustering,along with a multi-layer clustering method considering load spatiotemporal characteristics.Secondly,for typical load scenarios,a refined energy storage plan⁃ning model is constructed that comprehensively considers carbon emissions,lifecycle costs,penalties for curtailed wind and solar power,and the coordination of energy storage and distributed energy sources.Finally,a case study is conducted on an actual distribution network,resulting in optimal coordinated configurations of energy storage and distributed energy sources for different load scenarios.This validates the feasibility and effectiveness of the proposed model and method.
