Modeling the development of gas supply systems to create world forecasts of their development and interaction of gas markets is carried out on the basis of gas flow models. This paper presents a hierarchy of gas models, mainly foreign ones, their analysis, describes the capabilities, factors taken into account and the results obtained. In all considered models, data on gas supply systems are presented in aggregated form, although the methods of aggregation and their accuracy are not indicated. The paper briefly describes the developed methods of aggregation for solving problems of optimal development of gas supply systems with their multi-level modeling.
