Dear Mr. Haidar,

In the summary report, the reactive power from shunts and branch charging are both injections, so the reactive power balance can be expressed as ...

   Qgen - Qload + Qshunt - Qloss + Qcharging = 0

Dear Prof. Ray Zimmerman,

First, I would like to thank the authors of this package for giving us the chance to use it. I run the power flow for different cases which are saved in the downloaded Matpower file and I found that the reactive power in the summary report unbalanced. When computing the power balance, this should hold:

Qgen - Qload - Qshunt - Qloss


Please, advise

Regards

A. Haidar
