HI Dr. Ray Zimmerman,

 The problem is solved, Now I am able to retrieve the results. I was
just wondering, Is there any sort of plotting function available in

Matpower which can plot the whole power system. I mean the plot in which

I can view the buses, lines, generators and etc.

Thanking you,

Try this ...


%% define named indices into bus, gen, branch matrices

[PQ, PV, REF, NONE, BUS_I, BUS_TYPE, PD, QD, GS, BS, BUS_AREA, VM, ...

   VA, BASE_KV, ZONE, VMAX, VMIN, LAM_P, LAM_Q, MU_VMAX, MU_VMIN]
=
idx_bus;
[F_BUS, T_BUS, BR_R, BR_X, BR_B, RATE_A, RATE_B, RATE_C, ...
   TAP, SHIFT, BR_STATUS, PF, QF, PT, QT, MU_SF, MU_ST, ...
   ANGMIN, ANGMAX, MU_ANGMIN, MU_ANGMAX] = idx_brch;
[GEN_BUS, PG, QG, QMAX, QMIN, VG, MBASE, GEN_STATUS, PMAX, PMIN, ...
   MU_PMAX, MU_PMIN, MU_QMAX, MU_QMIN, PC1, PC2, QC1MIN, QC1MAX, ...
   QC2MIN, QC2MAX, RAMP_AGC, RAMP_10, RAMP_30, RAMP_Q, APF] =
idx_gen;
%% run the power flow
[baseMVA, bus, gen, branch, success, et] = runpf('case30');

%% see results
bus(:, [VM VA])
branch(:, PF)
gen(:, PG)


The first several lines just define a bunch of constants that you
can
use to address the columns of the data matrices.

Hi Everybody,

I am new to Matpower. I want to know how can we retrieve the stored
results of power flow. When I am reading the manual, It was there

gen(:, PG)

But when I am typing this in command prompt I am not getting any

Thank you very much,
