In this paper; a Hybrid Energy System (HES) configuration is modeled in Modelica. Hybrid Energy Systems (HES) have as their defining characteristic the use of one or more energy inputs; combined with the potential for multiple energy outputs. Compared to traditional energy systems; HES provide additional operational flexibility so that high variability in both energy production and consumption levels can be absorbed more effectively. This is particularly important when including renewable energy sources; whose output levels are inherently variable; determined by nature.

The specific HES configuration modeled in this paper include two energy inputs: a nuclear plant; and a series of wind turbines. In addition; the system produces two energy outputs: electricity and synthetic fuel. The models are verified through simulations of the individual components; and the system as a whole. The simulations are performed for a range of component sizes; operating conditions; and control schemes.
