The current situation in Europe calls for the need of urgent measures to find sustainable alternatives to its outer dependence on natural gas.Biomethane injection into the existing gas infrastructure is a fundamental opportunity to be promoted that, however, causes increasing complexities in the management of natural gas grids.At the gas distribution level, the lack of a monitoring system and suitable apunisw2 software for the simulation, management, and verification of gas networks may act as barriers to a widespread diffusion of a biomethane production and injection chain.
A transient fluid-dynamic model of the gas network is developed to perform estimations of the natural gas grid capacity in situations of production-consumption mismatch, taking into account the linepack as a gas buffer stock.The model is applied to the gas distribution network of a small urban-rural area.The aim is to assess the role of the linepack in determining the gas network receiving capacity and to test smart management of pressure set-points and injection flow rate to minimize biomethane curtailment.
Results show that biomethane unacceptability can be reduced baseball scoreboards for sale to 10% instead of 27% (obtained when following the DSOs state-of-the-art current procedures), thus highlighting the importance of the implementation of transient simulation software but also underlining the need for smarter control systems, actuators, and data management platforms for a transition to smart digital gas grids.
