Hello
Can I use rectangular coordinates in matpower ? for example I know
that there are real and imaginary parts of power injections and power
flows as well as bus voltages, but for branch current there is not
rectangular coordinate. Suppose that I want to add derivative of real
branch current w.r.t voltage to jacobian matrix. How can I do that ?

Hi Shiva,
In the last version of Matpower, you can use rectangular coordinates.
Check Technical note 4
(http://www.pserc.cornell.edu/matpower/TN4-OPF-Derivatives-Cartesian.pdf).
In Matpower, you have to specify the coordinates as
*opf.**v_cartesian=1*; before you solve the problem.
Best,
