TSPOPF

High performance AC optimal power flow solvers for MATPOWER

by Hongye Wang and Ray D. Zimmerman

TSPOPF is a collection of three high performance AC optimal power flow solvers for use with MATPOWER, a MATLAB® power system simulation package. The three solvers are:

PDIPM - primal/dual interior point method
SCPDIPM - step-controlled primal/dual interior point method
TRALM - trust region based augmented Lagrangian method

The algorithms are described in:

H. Wang, C. E. Murillo-Sánchez, R. D. Zimmerman, R. J. Thomas, "On Computational Issues of Market-Based Optimal Power Flow", IEEE Transactions on Power Systems, Vol. 22, No. 3, Aug. 2007, pp. 1185-1193.
doi: 10.1109/TPWRS.2007.901301

The PDIPM in particular is significantly faster for large systems than any previous MATPOWER OPF solver, including MINOPF. When TSPOPF is installed, the PDIPM solver becomes the default optimal power flow solver for MATPOWER. Additional options for TSPOPF can be set using mpoption (see help mpoption for details).
