摘要

分布式电源(DG)的接入使配电网供电能力的评估工作变得更加复杂。文中主要研究DG并网后对配电网供电能力的影响，通过判断矩阵法建立电网中不确定因数的盲数模型，提出了基于盲数理论的供电能力评估指标，并结合重复潮流法用以评估含DG的配电网供电能力。最后，算例对比分析验证了该方法的可行性和必要性。

Abstract

It is complicated to evaluate the power supply capability of distribution network with connected distributed generators(DGs). This paper mainly studies the influence of grid-connected DGs on the power supply capacity of the distribution network. The blind-number models of uncertainty factors in the power grid is developed though the judgement matrix method. A power supply capability evaluation index based on the blind-number theory is proposed. By combing with the repeated power flow method

the index is used to evaluate the power supply capability of the distribution network with DGs. Finally

the feasibility and necessity of the proposed method is verified by an example.This work is supported by Shanghai Green Energy Grid-integration Technology Engineering Research Center(No. 13DZ2251900).
