Problems dealing with the design and the operations of gas transmission networks arechallenging. The difficulty mainly arises from the simultaneous modeling of gastransmission laws and of the investment costs. The combination of the two yields a nonlinearnon-convex optimization problem. To...

This paper proposes a Benders-like partitioning algorithm to solve the network loading problem. The effort of computing integer solutions is entirely left to a pure integer programming solver while valid inequalities are generated by solving standard nonlinear multicommodity flow problems. The...

In this paper we present the regional techno-economic model ETEM, designed for the analysis of regional energy/environment systems and we show how it can be used to explore the possible penetration of new technologies in a region corresponding roughly to the canton of Geneva. We investigate...
