i simulated a standard 14 bus in matlab/PSAT . i want change one of my load and then show my result. for example in t=2 sec have a change and then in t=8 another. and my simulation time is 10 sec.
In MATLAB programming (even for PSAT), you just need to use a 'LOOP' in which the load is increased for each step and then the main code is run. Moreover, you can plot the result in each step to see its change trend.
