Research on flexibility analysis of integrated energy system

Regarding the research on the flexibility of the integrated energy system, firstly, this paper explains the necessity of flexibility for the development of the integrated energy system, and analyses the features of flexibility including the characteristics, the role, and the quantitative factors, which provides a basis for research on flexibility of integrated energy systems. Based on the above characteristics, this article explores the resources that can provide system flexibility in all aspects of the integrated energy system “source-network-load-storage”, and analyzes and evaluates their flexibility.
