Abstract

Integrating increasing capacities of renewable energy sources necessitates sector coupling. The coupling between the electricity and gas sectors is critical since they can be coupled bi-directionally via electrolyzers and gas turbines. Furthermore, the natural gas system must either be defossilized or the energy carrier must be switched to prevent greenhouse gas emissions. Hydrogen is expected to partially replace the currently used natural gas. Different infrastructure elements can be repurposed to transport hydrogen, which could reduce infrastructure costs significantly. Currently, the different systems are planned independently. However, planning the system using an integrated model might lead to significant cost reductions due to exploiting synergies between the systems. The integrated optimization could also enhance the system's reliability and efficiency.
We propose utilizing stabilized Bender's decomposition to optimize integrated energy systems, including the electricity, natural gas, and hydrogen sectors. This approach improves performance by effectively decomposing the problem into smaller, more manageable subproblems. Integrating bundle methods improves the convergence of Bender's decomposition.
We demonstrate the performance of stabilized Bender's decomposition within a case study of an IEEE system. The complex integrated energy system model can be solved close to optimality by adopting methodological advancements such as stabilized Bender's decomposition.
