Hi I have a question about state estimation in MATPOWER. In 118 bus system the slack bus is 69. The voltage and angle on bus 69 should be 1 and 0. But when I check Vlf (power flow voltage of bus 69) it is 0.9083 + 0.3784i. So, when I check the error in function runse
plot(180/pi*(angle(Vlf)-angle(V)),'.') It becomes big. Is it correct to put voltage magnitude and angle of bus 69 in the case 118 to one and zero? Thanks, Naime
