Dear All MATPOWER developers and users, I really hope some of you can give me some advice. I am working on sequential OPF simulations (not using MOST, but simply running MATPOWER's runopf in a loop and manually updating some values the MATPOWER case at each time-step t) to be performed on a case(s) that I have been working a lot to prepare. Anyway, unfortunately, now that the time of running the simulation has finally come, I have some serious convergence issues.
With the 285-bus case structs that I have built, the OPF simulation running with the default MIPS does not converge. The case structs differ one from another for some parameters as a function of t (time-step of the loop). Anyway, whatever the t I set, the OPF won't converge in any case, so there must be some structural issue of my cases I guess. I'll attach the case of t=1 to this mail for who wishes to have a look. Making some tests, I have found out that the PF simulation does not converge either. Among the (non-converged) results of the PF it seems that the slack bus is the only trying to generate active power (a lot of), whereas all the others do not dispatch, i.e. results.gen(:,PG) is zero for all the generators of the PV buses. What is more, the same generators dispatch very high quantities of reactive power, much beyond their lower and upper limits. If someone could help I would be very grateful... Last days for my thesis, very hard times! Thank you and best regards. Enrico
