摘　　要：大量小容量分布式能源可为电网提供调度服务,但同时也会带来管理负担。为此,本文提出一种基于同构多面体近似的分布式能源聚合方法。首先,建立分布式能源的广义可行域模型,并通过求不同分布式能源之间的闵可夫斯基和来获得聚合商的可行域模型。然后,采用基于同构多面体近似的方法简化闵可夫斯基和的求解。最后,考虑在大量异质参数分布式能源聚合的情境下,进行适当的聚类操作,以提升整体的近似精度。实验结果验证了所提方法的有效性和优势。A large number of small-capacity distributed energy sources can provide scheduling services for the power grids,but they can also impose a management burden.For this reason,this paper proposes a distributed energy aggregation method based on homogeneous polyhedral approximation.Firstly,a generalized feasible domain model of distributed energy sources is established,and the feasible domain model of the aggregator is obtained by finding the Minkowski sum between different distributed energy sources.Then,a method based on homogeneous polyhedral approximation is used to simplify the solution of the Minkowski sum.Finally,appropriate clustering operations are considered in the context of a large number of heterogeneous parametric distributed energy sources aggregated to improve the overall approximation accuracy.Experimental analysis demonstrated the effectiveness and the advantages of the proposed method.
