Abstract:

The difficulties in optimizing the steady-state gas network are the complex structure and big scale of the network, high nonlinearities of the objective and the constraints. In this paper, we formulate the steady-state gas network optimization as a mixed integer nonlinear programming model. Then based on the techniques of network reduction and linearization, we develop a new algorithm for the problem. Numerical results on an instance of the western natural gas network of China show that the proposed algorithm is promising.

Key words: gas network optimization, mixed integer nonlinear programming, linearization, mixed integer linear programming
