What is Multi-Energy System Optimization?
Multi-Energy System Optimization optimizes coupled electricity, heat, and transport sectors using MILP and MINLP models to minimize total system cost while incorporating power-to-X pathways and sector coupling synergies.
This subtopic models interactions across energy carriers to exploit synergies for cost-effective decarbonization. Research employs bottom-up optimization models covering power, heat, transport, and industry sectors. Over 20 key papers since 2010 address 100% renewable transitions with sector coupling, including works by Brown et al. (2018, 685 citations) and Bogdanov et al. (2020, 349 citations).
Why It Matters
Multi-energy optimization identifies cost savings from sector coupling, such as power-to-heat for excess renewables, enabling 100% renewable systems by 2050 (Bogdanov et al., 2019, 628 citations; Gabrielli et al., 2020, 255 citations). It supports policy design for EU Green Deal targets by modeling ETS impacts on power decarbonization (Pietzcker et al., 2021, 282 citations). Applications include regional feasibility studies for MENA 100% RE electricity by 2030 (Aghahosseini et al., 2020, 228 citations) and hydrogen storage for zero-emission systems (Gabrielli et al., 2020).
Key Research Challenges
Modeling Sector Coupling Complexity
Capturing nonlinear interactions between electricity, heat, and transport requires advanced MINLP formulations. Brown et al. (2018) highlight transmission reinforcement synergies, but scalability remains limited for global models. Prina et al. (2020, 352 citations) classify bottom-up models facing data and computational hurdles.
Handling Temporal Resolution Variability
High temporal granularity for VRE integration increases model size, complicating optimization. Bogdanov et al. (2020) integrate power, heat, and desalination but note storage modeling challenges. Gabrielli et al. (2020) address seasonal hydrogen storage yet face uncertainties in long-term dynamics.
Incorporating Policy and Uncertainty
EU ETS tightening and energy crises demand robust scenario analysis (Pietzcker et al., 2021). Farghali et al. (2023, 508 citations) review strategies amid geopolitical shocks, emphasizing adaptive models. Breyer et al. (2022, 469 citations) outline historical research gaps in uncertainty handling.
