The code looks correct to me. I’m not sure why the load margin decreases, but the changes in load (from positive to equally negative) may be forcing the OPF solution into generator dispatch solutions that somehow reduce the load margin. Ray > On Feb 15, 2017, at 10:45 PM, Majid Mehdizadeh

load reduction in continuation power flow (CPF)

2017-02-15 Thread Majid Mehdizadeh
Dear sir and matpower committee It is very strange for me that when the load of some PQ buses in IEEE 39 bus test system are reduced and then cpf is performed then the load margin of the system is becoming lower . It should be noted that i use the following code to estimate the load margin of the
