Alby’s Status Report for Mar 30

Accomplishments This Week:

  • Migrate all optimization code to a github submodule to clean up file hierarchy and simplify programming pipeline through a mirrored repo that fetches from the CMU SUGAR-D gitlab repo.
  • Added line-power functions to lines class and verified correct scaling with changes in load

Challenges Encountered:

  • Battery lambda gradient no longer converges with correct Lb equation stamp due to numerical tolerance issues.
  • Line-powers are incorrect by a factor of 2
  • Created an output function that generates a datastructure containing relevant optimization outputs for each period across all epochs.
    • line powers
    • generation powers
    • total generation
    • total cost
    • maximum and minimum voltages
    • battery state of charge
    • battery charge rate

Next Steps:

  • Fix numerical tolerance issues and investigate multi-period convergence across multiple epochs
  • Produce more example grid models to test the webapp
  • Further test the modifications of PQ loads to find limits
