Matpower 5.1 and constant impedance loads

Dear Matpower authors, I wish to use the Matpower software in my PhD research. I need to calculate power flow for the distribution system that consists of many constant impedance and constant power loads. After I read in the manual that " (...) the constant impedance portions can be modeled as

Re: Question

If you look at the formulation in equations (7.2)–(7.5) it should be clear that runopf_w_res() only deals with upward spinning reserves. In order to deal with downward spinning reserves–or any other class of

Re: question about losses

Hello Houssem, I don't know the reason why line Q-losses are reported that way in MATPOWER, but heuristically, if voltages are kept within reasonable bounds (say 0.9 to 1.10 in pu) then you can see that Q injections from line Bshunts will remain also bounded, as they are equal to Bs·V^2. By
