Dear Ray, It is good that you have released MATPOWER 7.0b1. I have a question. Did you check my last two commits? I have implemented voltage dependent loads for Cartesian coordinates for some tests and it can be used in the OPF computation as well. I think it is nice to release all four variants for both PF and OPF computations at same time. Do you think we can finish the variants of NR before the final release?

It would be great to have all of you try it out and shake out any bugs you can find before the final release of 7.0, which I hope to do before the end of 2018 if possible.

See the full release notes<https://github.com/MATPOWER/matpower/blob/master/docs/relnotes/MATPOWER-Release-Notes-7.0.md> and the CHANGES.md<https://github.com/MATPOWER/matpower/blob/master/CHANGES.md> file for more details. For release notes for previous versions, see Appendix H of the MATPOWER User's Manual<https://github.com/MATPOWER/matpower/blob/master/docs/MATPOWER-manual.pdf>. New Features: * New MATPOWER installer script install_matpower() * User-defined general nonlinear constraints and costs in AC OPF * PSS/E RAW export * Cartesian coordinate voltage and current mismatch formulations of AC OPF. * Three new radial power flow algorithms * Major update to OPF soft limit functionality * Many new functions and program options. New Case Files: * Seven new purely synthetic cases, up to 82,000 buses. * New RTS-GMLC<https://github.com/GridMod/RTS-GMLC> case. * Six new radial distribution system cases. New Documentation: * Two new Tech Notes, TN3<http://www.pserc.cornell.edu/matpower/TN3-More-OPF-Derivatives.pdf> and TN4<http://www.pserc.cornell.edu/matpower/TN4-OPF-Derivatives-Cartesian.pdf> * LaTeX source code for manuals Other Improvements: * Update versions of included packages: * MIPS 1.3. * MOST 1.0.1. * MP-Test 7.0b1. * Continuous integration testing via GitHub and Travis-CI integration. * Support in core optimization model for: * general nonlinear constraints * general nonlinear costs * quadratic costs * Refactor OPF code to take advantage of new opt_model capabilities for nonlinear constraints and quadratic and nonlinear costs. * Support for polar and cartesian voltages in derivative functions. * Improved performance (up to 2x speedup) for Newton power flow. * Handling of generator types, fuel types and bus names. * Numerous bug fixes. Incompatible Changes: * Move included MATPOWER case files to new data subdirectory. * Default soft limit behavior relaxes all constraints. * Minor corrections to data for Polish system cases. * Add mpopt to input args for some OPF callbacks.
