Hello Sir
In IEEE 57 bus, I fixed the capacity of transmission line and then increase the load and generation. I removed those lines whose power flow is more than their capacities. When the grid is divided into 4 parts. I remove the isolated buses. In island 1------- 45 buses are there including 7 generators. Matpower automatically considers the slack bus. But the DCOPF doesn't converge as the generation has a capacity of 1975.9 MW, but it dispatches only 928.9 MW. So there is a mismatch in load and generation. Load requirement is 1321.9 MW. Is there any mistake that I am doing? .
