摘要	虚拟电厂在分布式电源与电力系统的整合中扮演关键角色。但是由于不同的分布式电源其约束条件存在异构性，因此在准确描述这些资源的有功可行域聚合时面临着计算复杂度高及有功可行域聚合精确度不足的问题。本文提出一种新型电源型虚拟电厂有功可行域聚合方法，针对不同分布式电源的出力特性，建立各类分布式电源的数学单体模型，采取线性规划的方法来确定电源型虚拟电厂的有功可行域聚合边界，在保证有功可行域完整性的同时，极大提高了聚合计算效率。仿真结果表明，所提出的方法在应用于多时段资源聚合下，计算效率远胜于闵可夫斯基和方法；在有功可行域聚合精确度上，聚合平均误差为零，显著优于内近似法。
Abstract	Virtual power plants (VPPs) play a crucial role in integrating distributed generation into power systems. However, accurately characterizing the aggregated feasible active power region (FAPR) remains challenging due to the heterogeneous constraints of various DERs, leading to issues such as high computational complexity and insufficient precision in the aggregated region. This paper proposes a novel aggregation method to efficiently determine the FAPR of a generation-type VPP. The proposed method establishes mathematical models for individual DERs based on their output characteristics and employs linear programming to delineate the boundaries of the aggregated FAPR. Simulation results demonstrate that the proposed method substantially reduces computational complexity while completely preserving the accurate FAPR, outperforming the Minkowski sum approach in multi-period aggregation scenarios and achieving zero average aggregation error, thereby surpassing the precision of inner approximation methods in terms of FAPR aggregation accuracy.
