A graph neural network (GNN) method for assigning gas calorific values to natural gas pipeline networks

Energy, 2023
Calorific value metering offers unique advantages in the natural gas industry. Based on a graph neural network (GNN), this study proposes a method for metering the gas calorific value in natural gas transportation. Graph theory is introduced to consider the effects of physical topology and node properties in natural gas pipeline networks.
