Hi, I have a question about Matpower 4.0
By running" runpf('case9') " I get the power flow of the 9-bus system.
If I change baseMVA from 100 to 1000 or 10 in file 'case9.m',
the results of power flow do change completely! Why?
Is this because the r, x and b columns are expressed by p.u.-values?
If so, how do I have to transform them in order to receive the same
results as before? How do I choose a baseMVA value for an unknown
System?
Thanks very much
