Description

Plotting inflow from build_hydro reveals unrealistic peaks for MD. A similar peak is also present for DE, other countries were not investigated. The peaks in both cases exceed what is possible with existing hydro capacities (DE: factor 2 ca. 4.5 GW installed, MD: factor 5-10, ca. 50 MW installed)

Since these are only temporary peaks they probably don't affect the results too much, also because they are relatively low.

Ideas how to handle:

  • Change how the inflow is normalised, e.g. using in addition to the annual generation also the maximum installed capacity per country
  • Improve the quality of the inflow dataset
  • ?

Research direction

Start by locating the build_hydro entry point and reproduce the inflow plot for MD and DE. Compare the temporary peaks with the stated installed capacities, then determine whether normalization or the inflow dataset is responsible; done means the resulting peaks are physically plausible.
