Analysis of multi-output hybrid energy systems interacting with the grid: Application of improved price-taker and price-maker approaches to nuclear-hydrogen systems
TL;DR: In this paper , the authors explore the implications of alternative modeling approaches for nuclear-hydrogen IES focusing on a power system in the Midwest United States and compare the economic and operational outcomes across a spectrum of modeling approaches, including a non-hybridized base approach, a traditional price-taker approach that does not include the impact of hydrogen production on the electricity system, a power-system-focused price-maker approach that did not account for temporal hydrogen constraints, and two improved price-taking and price-making approaches that each address the impact.
