摘要：

随着分布式电源(DG)渗透率提高,配电网灵活性不足的问题日益凸显.围绕电能路由器(EER)展开研究,分析其对配电网灵活性的影响.首先,提出配电网转供灵活性指标用以表征配电网灵活性的一个方面;其次,分析EER的线性模型及相关约束条件,构建含有EER模型的主动配电网转供灵活性优化模型;最后,基于94节点交流配电网,设计不同场景,分析对比不同DG运行控制方式和EER参数对配电网转供灵活性的影响,验证EER提高配电网转供灵活性的有效性.

Abstract:

With the increase of the penetration rate of distributed generation (DG), lack of flexibility of distribution network has become increasingly prominent. This paper focuses on electric energy router (EER), and analyzes its impact on the flexibility of distribution network. First, the index of the transfer flexibility of distribution network is proposed to represent one aspect of distribution network flexibility. Then, the linear model of the EER and its related constraints are analyzed, and an optimization model of the transfer flexibility of the active distribution network with the EER model is constructed. Finally, based on the 94-bus alternating current distribution network, different scenarios are designed to analyze and compare the effects of different DG operation control modes and different parameters of EER on the transfer flexibility of distribution network. The effectiveness of EER in improving the transfer flexibility of distribution network is verified.

Key words: electric energy router (EER), transfer flexibility, second-order cone programming, distributed generation (DG), distribution network
