What's New in MATPOWER 8.0b1

Released Dec 22, 2022

Below are some of the highlights of the changes since version 7.1 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.

Major Redesign:

MATPOWER 8 introduces a major redesign and rewrite of all of the MATPOWER
internals in the form of the flexible, all-new MATPOWER object-oriented core
architecture (MP-Core) and new two user-level frameworks to access it.
(Previously developed under the name MP-Element in a separate repository
at https://github.com/MATPOWER/mp-element.)

  • MP-Core -- Provides unparalleled flexibility and customization capabilities
    at all levels. Facilitates new modeling (e.g. unbalanced multiphase elements, FACTS devices, etc.), new controls (e.g. optimization of transformer taps,
    PAR angles, etc.), new problem formulations, and more.
  • Flexible Framework -- Provides new top-level functions for running power
    flow (PF), continuation power flow (CPF) and optimal power flow (OPF), along
    with new MATPOWER Extension API for user access to the full customization
    capability of MP-Core.
  • Legacy Framework -- Allows MP-Core modeling to be used internally by
    legacy functions, facilitating use of legacy test suite.

See the new MATPOWER Developer's Manual and MATPOWER Technical
Note 5 for details of the new architecture. The User's Manual has
not yet been updated for the flexible framework.

New Features:

  • MIPS 1.5 adds to mplinsolve() the ability to save an LU
    factorization and reuse it to solve for additional right-hand sides.
  • MOST 1.2 adds calculation of expected temporal locational marginal
    price (TLMP), includes transitions into first period in ramping
    reserves, and more.
  • New options:
    • New AC power flow solver based on fsolve() function, selected by
      setting 'pf.alg' option to 'FSOLVE'.
    • New Implicit Z-bus Gauss method power flow for distribution systems,
      selected by setting pf.alg option to 'ZG'.
  • New functions/methods:
    • run_mp - Top-level function for running any task (PF, CPF, OPF) with
      the new MP-Core and flexible framework.
    • run_pf - Wrapper around run_mp for running PF.
    • run_cpf - Wrapper around run_mp for running CPF.
    • run_opf - Wrapper around run_mp for running OPF.

New Case Files:

  • Two new European case files. Thanks to Florin Capitanescu.

New Documentation:

Other Improvements:

  • New MATPOWER Docker image (named matpower/matpower) is
    based on the official GNU Octave image (gnuoctave/octave) and
    is available for multiple MATPOWER and Octave versions.
  • Update versions of included packages:
    • MP-Test 8.0b1.
    • MIPS 1.5.
    • MP-Opt-Model 4.1
    • MOST 1.2.
  • Numerous bug fixes.

Incompatible Changes:

  • Remove several deprecated functions, methods and options.
