"Twinp2g: A Digital Twin Architecture for Optimal Power-to-Gas Planning"

Abstract

Power-to-Gas (P2G) is an emerging technology aiming to contribute towards addressing the climate change and environmental degradation. Yet, numerous factors need to be taken into consideration to for practical P2G applications. Digital Twins (DT) are used for simulation and optimization purposes, allowing investigation and prediction of their short-, medium-and long-term results. This paper presents a DT architecture, namely TwinP2G, that aims to couple the electrical power and natural gas sector by enabling multi-resolution simulations and optimization relating to the integration of P2G plants and regenerative hydrogen fuel cells (RHFC) in the power grid. The suggested solution is meant to be applied initially in the Greek energy system enabling data-and simulation-driven P2G and fuel cells optimal planning and techno-economic analyses. This piece of work concludes with future application plans and application development perspectives.
