Abstract

With the deepening of digital transformation and the rise of technologies such as big data and the Internet of Things,many new types of business scenarios are emerging,and the related systems are becoming increasingly complex.In this context,the field of digital power grid is also facing brand-new challenges,especially more stringent requirements on the real-time performance of the system.How to efficiently evaluate the performance of digital power grid business scenarios,and then provide support for improving the performance reliability of the system,is an important issue.In this paper,we propose a modeling and performance analysis method for the digital power grid business scenarios,and implement a prototype tool,BizModeler.We firstly propose a visual modeling language DPG(Dataflow-based Performance Graph)for the characteristics of the digital grid domain; secondly,we summarize the common performance indicators in the digital grid domain and propose a model performance analysis method based on the synchronous data flow graph; finally,we verify the usability and effectiveness of the method through the implementation of the tool as well as an example study.
