Jacobian-Based Method for Natural Gas Energy Flow Analysis in Transmission-Level

This paper presents a comprehensive steady-state gas load flow analysis considering all elements and fundamentals of gas networks. The reason is the increasing usage of natural gas carrier in the industry because they have a higher efficiency. In this paper, interdependencies of the mentioned infrastructures are considered in detail including a nonlinear part-load efficiency performance for units. A Jacobian matrix-based framework is proposed to solve the energy flow problem according to the Newton-Raphson technique. This method omits the use of any extra variable and it is able to model any equipment of natural gas network in the Jacobian matrix. A typical ۲۰-node natural gas network is used to evaluate the outputs of the proposed method. In addition, sensitivity analysis is also provided.
