Take a look at how Sbus is created in opf_consfcn by extracting Pg, and Qg from the solution vector x. You need to do something similar with Ybus. Shri From: Mirish Thakur mirishtha...@gmail.commailto:mirishtha...@gmail.com Reply-To: MATPOWER discussion forum

The constraints corresponding to columns 11-21 in the gen matrix are optional (i.e. the columns can contain all zeros), but those columns are not to be treated as optional columns. It turns out that some functions, such as runopf() will not cause an error and, yes, the results returned are
