  • varargin/varargout functions have been split into separate functions.

    This includes:

    • ext2int (ext2int_mpc, ext2int_old)
    • loadcase (loadcase_embedded)

  • Structs are typed into dataclasses:

    • mpc: the case file
    • mpoption: the option struct

  • Several cases are backported from MATPOWER 8.1.

    • case1197
    • case11kundur
    • case145
    • case18
    • case300
    • case533mt_hi
    • case533mt_lo
    • case59
    • case_ieee30

  • Functions not supported by pwrs:

    • Root package:
      • Contents: stub
      • caseformat: stub
      • cdf2mpc: not planned
      • d2AIbr_dV2: WIP
      • d2ASbr_dV2: WIP
      • define_constants: not applicable for Python code
      • fmincopf: fmincon is only available in MATLAB
      • have_feature_*: not applicable for pwrs
      • miqps_matpower: deprecated code, not planned
      • mpoption_info_*: not planned, strictly typed into dataclasses
      • poly2pwl: not planned
      • psse*: not planned
      • runduopf: not planned
      • runopf_w_res: not planned
      • runuopf: not planned
      • toggle_iflims: WIP, low priority
      • toggle_reserves: WIP, low priority
      • toggle_softlims: WIP, low priority
      • uopf: WIP, low priority
    • MIPS/PIPS:
      • Contents: stub
      • have_feature_*: not planned
    • MOST/POST:
      • *: WIP, low priority

  • Functions has different calling conventions:

    • all:
      • The callee may modify the parameters, in-place.
    • d2Sbr_dV2: the connection matrix will always be dense

  • Solvers supported in pwrs:

    • For mplinsolve:
      • Dense solver:
        • LAPACK _gesv: from numpy.linalg.solve
      • Sparse solver:
        • SuperLU: from scipy.sparse.linalg.splu / scipy.sparse.linalg.spsolve
        • KLU: from nbklu
