Dear all, I’m using Matpower to run load flow for IEEE-24 bus system. I would appreciate if anybody can help me on the followings:
1) I just wonder why the difference between buses’s sending power and buses’s receiving power (for branch) doesn’t tally with the resulted line losses? For example (please refer to highlighted area in the attachment), at branch 1, bus 1 is sending 11.94-j26.92MVA and bus 2 receives -11.94-j22.45MVA. Logically, the losses will be 0-j4.47MVA ([11.94-j26.92MVA]-[-11.94-j22.45MVA]). But, the resulted line loses connecting the two buses are 0.004+j0.02MVA. Is that possible? 2) Is anybody here working on the same system as I am? Can you help me to verify the result (please refer to attachment)? 3) I’ve compared the result with other load flow software. It seems that the voltage magnitude and active power losses do not differ much. But, the voltage angle and reactive power losses vary significantly. Isn’t all the results should be approximately the same? Thank you
