TSPOPF  is a collection of three high performance AC optimal power ﬂow solvers for
The algorithms are described in [8, 43]. The ﬁrst two are essentially C-language implementations of the algorithms used by MIPS (see Appendix A), with the exception that the step-controlled version in TSPOPF also includes a cost smoothing technique in place of the constrained-cost variable (CCV) approach for handling piece-wise linear costs.
The PDIPM in particular is signiﬁcantly faster for large systems than any previous
