What's New in MATPOWER 7.0

Released May 17, 2024

Below is a summary of the changes since version 8.0b1 of MATPOWER. See the CHANGES.md file for all the gory details. For release notes for previous versions, see Appendix H of the MATPOWER User's Manual.

New Features:

  • MP-Opt-Model 4.2 adds support for:

    • Memory savings via optional use of transpose of linear constraint matrix.
    • Display of solved model solution.
    • MATLAB Optimization Toolbox 9.5 and later (MATLAB R2023a and later).

    For details, see the release notes for MP-Opt-Model 4.2 (also in Appendix C in the MP-Opt-Model User's Manual).

  • MOST 1.3 improves speed and memory usage on certain problems. For details, see the release notes for MOST 1.3 (also in Appendix B in the MOST User's Manual).

  • SimulinkMATPOWER, included in MATPOWER Extras, enables the use of MATPOWER from MATLAB's Simulink® environment. Thanks to Lukas Ortmann.

New Case Files:

  • Two new Swedish distribution system cases. Thanks to Gabriel Malmer.
    • case533mt_lo -- 533-bus case, DSO Kraftringen, low net-load scenario
    • case533mt_hi -- 533-bus case, DSO Kraftringen, high net-load scenario

New Documentation:

Other Improvements:

  • New option to makeLODF() to replace with NaN any columns corresponding to "bridge" branches which, if removed, result in islands. Thanks to Liangyu Zhang.
  • Update versions of included packages:
    • MIPS 1.5.1
    • MP-Opt-Model 4.2
    • MOST 1.3
    • MP-Test 8.0

Bugs Fixed:

  • Fix bug #210 where radial power flow methods resulted in numerical error with multiple generators at a bus. Thanks to Mirko Todorovski.
  • Fix bug #223, fatal error in save2psse() for cases with dispatchable loads. Thanks to Ali Jahanbani.
  • Fix crash in radial_pf() under MATLAB R2016a and earlier.
  • Delete extra (duplicate) row in gencost in case94pi.m.
