STEM foundation of Energy Nexus

The science, technology, engineering and mathematics Energy Nexus rests on. Each method has a canonical page in the STEM Commons, hosted by GCRI, and a page here on how it is applied in this field.

01In brief

The short answer.

The Energy Nexus STEM foundation is the set of canonical methods its findings depend on, from energy generation, storage and grid technology to process and industrial safety engineering. For the Consortium, Energy Nexus stewards energy generation, storage and grid technology as well as power systems engineering. Each method has a canonical STEM Commons page and a page here on its use in the energy field.

STEM foundation of Energy Nexus: N-1 security assessmentState estimation gives the operating point; every contingency on the list is simulated with an AC power flow; limit violations lead to remedial actions and a security-constrained dispatch that the operator approves. Design of the process, not a record of a run.

05Method mix

Why energy needs this combination of methods.

Energy risk is a problem of engineered networks under weather and market stress. Power engineering and energy technology describe the system, forecasting and optimisation plan and run it, network science and resilience engineering describe how it fails and recovers, and materials chemistry and process safety cover fuels, batteries and plants.

06Why it matters

Grounding makes claims checkable.

When a finding names the methods it depends on, a reader can see its assumptions and limits, and an expert in that method can challenge it.
