Abstract

Nowadays, microgrid is utilised as a flexible replacement to the conventional power system. Therefore, special attention must be provided for the proper microgrid based power system design. Earlier, various articles presented the interconnected microgrid operation. However, less attention is given towards the proper tie-line modeling considering high resistance-inductive reactance (R/X) ratio in the interconnected microgrid operation. Considering the research gap, towards the proper designing of tie-line modeling, this paper presents an improved power tie-line model in an interconnected microgrid in presence of plug-in electric vehicle. Various case studies are carried out for validating the proper designing technique under various load disturbances in presence of uncertain output power from intermittent power generating units. The functioning of the proposed work is validated, connecting the proposed model in a 12-node distribution network. The proposed model shows its effectiveness and superiority compared to other available designing conditions.

AGC运行下基于PEV的互联微电网的改进联络线功率模型设计

目前，微电网已成为传统电力系统的灵活替代品。因此，合理设计基于微电网的电力系统必须引起特别的重视。此前，各种文章介绍了互联微电网的运行。然而，在互联微电网运行中，考虑到高电阻-感应电抗(R/X)比，合理的联络线建模却很少受到重视。考虑到研究的空白，针对插电式电动汽车存在的互联微电网，本文提出了一种改进的插电式电动汽车存在的互联微电网电力插线模型。为验证在间歇发电机组输出功率不确定的情况下各种负荷扰动下的合理设计技术，进行了各种实例研究。将所提出的模型连接到一个12节点的配电网络中，验证了所提出的工作的功能。与其他可用的设计条件相比，该模型显示了其有效性和优越性。
