An MIP Model with Endogenous Capacity Investment for Energy Transition Pathways - Interrelation Between Power-to-X, demand Response and Market Coupling

This research proposes a new long-term energy planning model with endogenous capacity investment and energy dispatch with consideration of Power-to-X and demand response technologies. The model represents an energy system and minimizes the total capacity investment cost, across all technologies, and the operational cost incurred in satisfying demand levels. Different demand sectors and their links are also modeled. Particularly, we explicitly consider the links between the electricity, heat, and electro-fuels (Hydrogen), and V2G. The model is used to analyse the Croatian energy system under different policies of RES levels and CO2 reduction targets. We show that Power-to-X indeed provides the required flexibility to the new capacity additions of variable renewable sources, reaching systems with lower levels of critical excess of energy production. Battery storage and Power-to-heat strategies are largely adopted for renewable shares and CO2 savings around 80% while below such values their adoption is limited. Also, power-to-heat technologies become predominant when a limit on CO2 emissions of the heating sector is required and particularly when the renewable share in electricity reaches a value of 60%.
