论文摘要
可再生能源扩散呼吁网格操作员和计划者系统地评估分布式能源（DERS）的潜在影响。考虑到各种基于逆变器的资源（IBR）之间的显着差异，尤其是网格形成逆变器和网格构成逆变器之间的不同功能，除了具有高度计算负担的可用共模拟框架外，开发有效有效的评估程序至关重要。本文为集成电源系统传输和分销网络提供了简化的基于图的拓扑评估。基于修改的MiniWecc网格模型的集成图和IEEE 8500节点测试馈线模型，具有40个节点的高性能计算平台进行了图分析，并已利用总计2400 CPU来处理此集成图，该图具有100,000+节点和10,000多个IBR。节点排名结果不仅验证了所提出的方法的适用性，而且还揭示了分布式网格形成（GFM）和网格之后（GFL）逆变器与集中式电厂相互作用的潜力。
The renewable energy proliferation calls upon the grid operators and planners to systematically evaluate the potential impacts of distributed energy resources (DERs). Considering the significant differences between various inverter-based resources (IBRs), especially the different capabilities between grid-forming inverters and grid-following inverters, it is crucial to develop an efficient and effective assessment procedure besides available co-simulation framework with high computation burdens. This paper presents a streamlined graph-based topology assessment for the integrated power system transmission and distribution networks. Graph analyses were performed based on the integrated graph of modified miniWECC grid model and IEEE 8500-node test feeder model, high performance computing platform with 40 nodes and total 2400 CPUs has been utilized to process this integrated graph, which has 100,000+ nodes and 10,000+ IBRs. The node ranking results not only verified the applicability of the proposed method, but also revealed the potential of distributed grid forming (GFM) and grid following (GFL) inverters interacting with the centralized power plants.
