H.5 Version 3.0 – released Feb 14, 2005

The Matpower 3.0 User’s Manual is available online.⁷⁸

New Features

• Compatibility with Matlab 7 and Optimization Toolbox 3.
• DC power flow and DC OPF solvers added.
• Option to enforce generator reactive power limits in AC power flow solution.
• Gauss-Seidel power flow solver added.
• Support for MINOS-based OPF solver added (separate package, see
  http://www.pserc.cornell.edu/minopf/ for more details)
• Multiple generators at a single bus.
• Saving of solved cases as M-files or MAT-files.
• Loading of input data from M-files, MAT-files, or structs.
• Improved decommitment algorithm.
• Added a very incomplete test suite.
• Handling of dispatchable loads in OPF, modeled as negative generators with constant power factor constraint.

Bugs Fixed

• Phase shifters shifted the wrong direction.
• Minor fixes to IEEE CDF to Matpower format conversion (reported by D. Devaraj and Venkat)
• Flows on out-of-service lines were not being zeroed out. (reported by Ramazan Caglar)
• Reported total inter-tie flow values and area export values were incorrect.
• Several other bugs in solution printouts.
