HI when I increase the load in bus 7 and 9 in case9 (I prouduct the P and Q of This buses in 2.5284 (they are critical buses by modal analysis) to decrease the min eigenvalue of system to 0.0487, the slack bus converting to PQ bus and bus 2 is new slack bus,all voltage of buses decreas in this case but the voltage of bus 1(new pq bus) increase to 1.103 why is it?is it for change slack from bus 1 to bus 2?
