Abstract:
In an energy framework where biomethane injection into the existing gas infrastructure is gaining importance, the management of natural gas grids is becoming increasingly complex. At gas distribution level (urban and rural), the lack of monitoring system andsuitable software for the simulation, management and verification of gas networks under these new operating circumstances may act as barriers towards a widespread diffusion of a biomethane production and injection chain. A transient fluid-dynamic model of the gas network was developed with the additional feature of considering the natural gas stream as multi-component and time-dependent mixture of gases. In this way, it is possible to perform quality-tracking simulationsand estimations of the natural gas grid capacity, taking into account the linepack as a gas buffer stock. In the present work, the model is applied to the gas distribution network of a small urban area. The aim isto assess the role of the linepack in determining the network capacity and to show the diffusion of biomethane throughout the network. The final scope is to highlight the importance of the implementation of transient and quality-tracking simulation tools in order to safely include biomethane and, more generally, renewable gases within the existing infrastructure.
