Use Cases

GEMS modelling language was primarily designed for the following purposes:

  • Adequacy Assessment: GEMS enables the modelling of energy system adequacy problems, describing an energy system’s ability to supply demand across time horizons and scenarios.
  • Economic Dispatch: GEMS supports the modelling of economic dispatch problems, in which the dispatch levels of electricity generators are defined within an optimisation framework that aims to minimise system costs while satisfying demand and operational constraints.
  • Energy System Planning: GEMS can be used to model planning problems that support the strategic development and coordination of electricity infrastructure for long-term, reliable, and cost-effective energy supply.
  • Multi-Energy modelling: GEMS allows the modelling of multi-energy systems. While Antares Simulator primarily focuses on the electric grid, GEMS extends the modelling scope to integrated multi-energy systems.
  • Antares Simulator Legacy Integration (Hybrid Mode): GEMS can be used in conjunction with Antares Simulator legacy studies through a hybrid simulation mode, where a study combines two modelling components: one based on the legacy framework and one based on GEMS.

As a general-purpose algebraic modelling language, other use cases can also be envisioned for GEMS.
