Intragas - A Stylized Model of the European Natural Gas Network [PDF]
SSRN Electronic Journal, 2009 We present an optimization model of the European natural gas market which is intended for the use within a regulatory approach providing incentives for efficient transmission investments. The stylized model is designed as welfare maximization taking into account production, pipeline, LNG, and storage constraints. We develop several scenarios to analyze
