There are two lists MATPOWER-L (for discussion) and MATPOWER-ANNOUNCE-L (announcements only). It looks like you are subscribed to the 2nd but not the first.
1. For details on extending the OPF formulation, please read chapter 6 in the User's Manual. I'm not sure what you mean by minimizing cost in runmarket ... that's essentially what it already does. Voltages are already included as optimization variables (see equation (5.5)). Currents can be computed directly from the voltages. 2. MATPOWER does not save directly to Excel files. However, you can open text files from within Excel and I believe Matlab has functions for saving Excel files.
