Question about the Unit of the Jacobian Matrix

[Steven Geng]

Dear Matpower Users/Developers,
I have a question about the Jacobian Matrix that makeJac() returns, could
you please help me with it? Thanks a lot!

The question is about the unit of the Jacobian matrix. For example,
for the [image:
\frac{\partial P}{\partial |V|}] part,* is it (a)  MW / p.u.; or (b) MW /
Volt; or (c) p.u. / p.u.; or (d) p.u. / Volt?*

Similarly, for the [image: \frac{\partial Q}{\partial \theta }] part,
is it *(a)
 MVar / degree; or (b) MVar / rad; or (c) p.u. / degree; or (d) p.u. / rad?*

Thanks for your time and apologize if this is a naive question.

Best,
Steven
