The ASSET Lab Resource adequacy package (assetra) is a light-weight, open-source energy system resource adequacy package maintained by the University of Michigan ASSET Lab.

Features

  • Probabilistic Monte Carlo state-sampling simulation framework, supporting:
    • Time-varying forced outage rates in thermal units

    • Sequential storage unit dispatch

    • User-defined energy unit types

  • Resource adequacy calculation:
    • Expected unserved energy (EUE)

    • Loss of load hours (LOLH)

    • Loss of load days (LOLD)

    • Loss of load frequency (LOLF)

  • Resource contribution calculation:
    • Effective load-carrying capability (ELCC)

  • Object-oriented interface to manage energy units within energy systems

  • Internal computation stored in xarray datasets
