Re: get DC power flow matrix in IEEE 14 bus system from matpower

[Ray Zimmerman]

Since case14 already has consecutively numbered buses starting at 1, you don’t 
need to worry about conversions to and from internal indexing.

So, for the PTDF matrix …

  mpc = loadcase('case14');
  PTDF = makePTDF(mpc.baseMVA, mpc.bus, mpc.branch);

For the B matrix …

  [Bbus, Bf, Pbusinj, Pfinj] = makeBdc(mpc.baseMVA, mpc.bus, mpc.branch);

Hope this helps,

    Ray
