 INTRODUCTION
--------------

MATPOWER is a package of Matlab m-files for solving power flow and
optimal power flow problems. It is intended as a simulation tool for
researchers and educators which will be easy to use and modify. MATPOWER
is designed to give the best performance possible while keeping the code
simple to understand and modify.

It was developed by Ray Zimmerman and Deqiang Gan of PSERC at Cornell
University (http://www.pserc.cornell.edu/) under the direction of Robert
Thomas. The initial need for Matlab based power flow and optimal power
flow code was born out of the computational requirements of the PowerWeb
project (see http://www.pserc.cornell.edu/powerweb/).

More documentation is available in the User's Manual (manual.pdf) and in
the m-files themselves (type: help <name of m-file> at the Matlab
prompt). Documentation for the case file format can be found in case.m.
Where something is still unclear, the source code IS the documentation
:-)

MATPOWER is free. Anyone may use it. Anyone may modify it for their own
use as long as the original copyright notices remain in place. Please
don't distribute modified versions of MATPOWER without written
permission from us.

We do welcome contributions of code which you feel would be a worthwhile
addition to MATPOWER.


------------
 WHAT'S NEW
------------

Here is a list of primary changes from version 1 to version 2:

- greatly enhanced output options
- added fast-decoupled power flow
- optimized building of Ybus and Jacobian matrices
  (much faster on large systems, especially in Matlab 5)
- highly improved unit decommitment algorithm
- included optional costs for reactive power generation in OPF
- completely rewritten LP-based OPF solver
- consolidated parameters in MATPOWER options vector

... and of course ...

- fixed some bugs


-------------
 QUICK START
-------------

What you need:
    a Mac, UNIX box, or PC with ...
        - Matlab 4 or higher
        - Optimization Toolbox (for some OPF algorithms)

Installation:
    - Unpack the distribution
    - Copy all of the m-files in the MATPOWER distribution to a
      location in your Matlab path.

To run a simple power flow with default 9-bus system and all default
options, at the Matlab prompt, type:
    >> runpf

To run a power flow on the 118-bus system:
    >> runpf('case118')

To run an optimal power flow on the 9-bus system with all defaults:
    >> runopf

To run an OPF on the 30-bus system:
    >> runopf('case30')

To run an OPF with option to decommit expensive generators:
    >> runuopf('case30')

For info on other parameters and options, try these:
    >> help runpf
    >> help runopf
    >> help runuopf
    >> help mpoption

or:
    >> help <name of any other m-file>

 KNOWN BUGS
------------

Please report any bugs you find to Ray Zimmerman <rz10@cornell.edu>.

- MathWorks bug: constr does not correctly handle negative lambdas
- identification of binding constraints in printpf.m should
  use OPF_VIOLATION instead of size of MU
- 'area' is the name of an m-file in Matlab 5, my variable 'area'
  masks this m-file
