IEEE 39 bus load flow simulation error using simulink

I am having this problem during load flow simulation of IEEE 39 bus system.Load flow is not converging.How can we reduced the value?

Can anyone help me out?

Hi Debmalya,

I understand that you are currently working on a load flow simulation of the IEEE 39 bus system, and you are encountering convergence issues. Based on the image you attached, it appears that the warning is likely due to a high Base Power value causing the rated values in the admittance matrix to become too small.

To address this issue, I recommend adjusting the base power to a less value. By doing so, you should be able to overcome the convergence problem and remove the warning you are facing as the power balance is achieved.

For more details regarding the load flow simulation and convergence issues, please refer to the following MATLAB Answer thread:
