Hi Iman,
The magnitude and angle of bus voltage can be extracted as follows.
Where the output variable 'results' is in structure format.
==================Type in command window ===============
define_constants;
results = runpf('case14');
success=results.success ; % success flag, 1 = succeeded, 0 = failed
Vm=results.bus(:,VM); % Bus Voltage Magnitude
Va=results.bus(:,VA); % Bus Voltage Angle
Pg=results.gen(:, PG); % generator real power injections
Qg=results.gen(:, QG); % generator reactive power injections
======================================================
You can find more details about the extracting all components of power flow
results in section 4.3 and table 4-1 in the manual. Hope this helps.
