DEMOSES

Energy transition decision makers are sailing in the dark. The energy system is rapidly becoming more complex. To accommodate the rapid growth of renewables and the electrification of demand, the energy system is becoming increasingly integrated. However, the computational modelling tools for that are used for decision support are not keeping. They are still largely limited to one energy carrier, one network level, and either technical or economic in nature. By advancing the development of model coupling software, DEMOSES will enable the required increase in the scope of energy system analysis. Building on existing software technology for connecting models, we will develop a methodology and software tool for coupling computer models. The resulting break-through in the scale of energy systems modeling provides market parties and network operators with better insight in the future performance of their assets. Policy makers will similarly benefit from the improved understanding of the effects of regulatory changes. We will apply the developed model coupling approach to three areas in which we expect large benefits from energy systems integration: the need for electricity TSOs and DSOs to integrate their operations, the increasing interdependence of the gas, electricity and heat networks and the integration of large-scale and consumer-side flexibility options. Finally, we will integrate these cases in a study of the integration of gas, heat and electricity networks in the province of South Holland.
