What’s New in MATPOWER 7.1

Below are some of the highlights of the changes since version 7.0 of MATPOWER. See the full release notes and the CHANGES.md file for more details. For release notes for previous versions, see Appendix H of the MATPOWER User’s Manual.

New Features

  • Core optimization model and solver interfaces released as separate
    package (included), MP-Opt-Model 3.0, bringing many enhancements:
    • Support for new QP solver OSQP for DC OPF
    • New unified interfaces for nonlinear programming and nonlinear equation
      solvers
    • Many new features of the opt_model class, including a solve()
      method that selects and calls the appropriate solver based on the
      automatically detected problem type, and methods for extracting
      specific variables, costs, constraint values and shadow prices, etc.
      from a solved model
    • Performance improvements
  • MP-Test 7.1, with new modular, extensible have_feature() function
    for detecting optional functionality
  • New options and speed improvements for computing shift factors.
  • Numerous new functions and program options.

New Case Files

  • Nineteen new distribution system cases [ref 1, ref 2].

New Documentation

Other Improvements

  • New implementation of Newton power flow for cartesian voltage
    representations.
  • Improved robustness of Newton power flow with hybrid voltage updates.
  • Significant performance improvement for CPLEX on small DC OPF problems.
  • Update versions of included packages:
    • MIPS 1.4.
    • MOST 1.1.
    • MP-Test 7.1.
  • Numerous bug fixes.

Incompatible Changes

  • Update case18, case22, case69, case85 and case141 to more closely
    match data from original papers, thanks in part to case files contributed
    by Houssem Bouchekara, et al. Solutions for updated cases may not match
    exactly. See help text in case files for details.
