Hi Hasan, If you open case9.m you'll see the bus matrix. You need to change the value of *Vmax Vmin *values from bus matrix like I changed it for buses you want. I think you need to do this: %% bus data % bus_i type Pd Qd Gs Bs area Vm Va baseKV zone Vmax Vmin mpc.bus = [ 1 3 0 0 0 0 1 1 0 345 1 *1.2 0.8;* 2 2 0 0 0 0 1 1 0 345 1 *1.2 0.8;* ; 3 2 0 0 0 0 1 1 0 345 1 *1.2 0.8;* ; 4 1 0 0 0 0 1 1 0 345 1 *1.2 0.8;* ; 5 1 90 30 0 0 1 1 0 345 1 1.1 0.9; 6 1 0 0 0 0 1 1 0 345 1 1.1 0.9; 7 1 100 35 0 0 1 1 0 345 1 1.1 0.9; 8 1 0 0 0 0 1 1 0 345 1 1.1 0.9; 9 1 125 50 0 0 1 1 0 345 1 *1.2 0.8;* ; ];
This relaxation is arbitrary, I changed it to *1.2 (max) and 0.8(min),* you can make it flexible as you wish.
