Model name

GHOST microgrid

Minimum license required

HXG Max (1 core)

Highlights

  • Only simulation tool capable of simulating this network at 21 us without decoupling
  • The highest number of single-phase nodes (695) of all benchmarks on 1 core at 21 us, which would be equivalent to 1655 nodes at 50 us on 1 core
  • Capable of reaching on a single core typical time-steps required for studies demanding higher resolution due to higher PWM frequencies of converters

Known distributed energy resources benchmark originally published by the MIT and NREL. Few alterations were made to remove the need for an external controller for the purpose of this benchmark.

Hardware

OP5707XG

  • Motherboard: X11DPL-i
  • Processor: Intel(R) Xeon(R) Gold 5222 CPU @ 3.80GHz; 8 cores
  • RAM: 32 GB

Software

  • Platform: HYPERSIM
  • Compiler: GCC 8.3.0

Results

  • Number of core(s): 1
  • Minimum time-step: 21 us *
  • Total average execution time: 18.1 us

* Performance under transient conditions varying considerably depending on the study type, this benchmark measures the minimum achievable time-step without overruns in steady-state conditions. A rule of thumb is to consider 10 to 20 % buffer time for calculations under transient conditions.
