MATPOWER 4.0b5 is available for download from the MATPOWER home page ...
http://www.pserc.cornell.edu/matpower/
The primary changes from version 4.0b4 are:
* New features:
- Added support for MOSEK to solve LP and QP problems. Set option
OPF_ALG_DC = 600 to use MOSEK to solve the DC OPF. Requires the
Matlab interface to MOSEK, available from http://www.mosek.com/.
See 'help mpoption' for more MOSEK options.
- Added support for CPLEX to solve LP and QP problems. Set option
OPF_ALG_DC = 500 to use CPLEX to solve the DC OPF. Requires the
Matlab interface to CPLEX, available from
http://www.ibm.com/software/integration/optimization/cplex-optimizer/.
See 'help mpoption' for more CPLEX options.
- Added modcost() for shifting and scaling generator cost functions.
- Added load2disp() for converting from fixed to dispatchable loads.
- Added makeJac() to form the power flow Jacobian. Optionally returns
the system admittance matrices too.
- Performance optimizations in opf_consfcn() for large systems.
* Bugs fixed:
- When called without output arguments, uopf() was not printing any
output.
- Indexing bug in dcopf_solver() affecting certain cases with a mix
of polynomial and piecewise linear costs.
