Coupled Heat and Electricity Scenarios

The ongoing project examines when the coupling time step between a heat model and an electricity model changes the assessment of load peaks and thus the conclusion.

P05 · Ongoing · Simulation & Modelling

Problem

Different time steps in coupled sub-models can change the assessment of load peaks. A conclusion may then depend on the chosen step size rather than on the modelled system.

Research question

When does the coupling step size influence the conclusion? The aim is a justified threshold beyond which coarser coupling alters the statement.

Method

The work uses a simplified heat/electricity model, a controlled time-step comparison and synthetic load profiles. The runs take place in the modelling workshop.

Evaluation criteria

Balance deviation, deviation of load peaks and computational effort are compared against a finer reference run. Results are not yet available.

Expected outcome

A traceable choice of step size is expected, in place of a spuriously precise grid forecast. The project is ongoing; results are outstanding.

Limits

The project provides no real grid design, no supply guarantee and no economic optimisation.
