Obtain dynamics of tie-line power in the simulation

[zhui99]

Hi,
I would like to inquire how to gain data of transmission power or tie-line power in the time-domain simulation (TDS). Is there any model that can measure the tie-line power?
Thank you!

For now, line flows are not stored to the output array, so its retrieval will require some coding. The Line.a1.e array, for example, stores the active power at the sending end. Similarly, “a2” is for the active power at the receiving end. “v1” and “v2” are the reactive power at the sending or receiving ends. Best regards,Hantao CuiOn May 29, 2025, at 9:09 PM, Wu Zhuorui ***@***.***> wrote: Hi, I would like to inquire how to gain data of transmission power or tie-line power in the time-domain simulation (TDS).

Thanks! I will check it.
