Thank you. I will move over to the DEV-list.

The complex part about adding the feature is becoming familiar with the existing structure of most.m and toggle_dcline.m. Once you have a confident grasp of the code in both of those, it should be relatively straightforward to implement. This would be a nice addition if you are able to implement it. And I suppose it would make sense to move any further discussion to the MATPOWER-DEV-L list.

Say by adding generators by hand and adding the pf, pt relationship equation to the optimization problem? Also, what do you think how complex would it be to add this feature to most? I may be able to help working on that.

We use most to solve the multiperiod dcopf problem. When using matpower’s rundcopf we get a reasonable solution and can read the output for the power flow over the dcline in the result structure. (result.dcline) But when we use most to solve the problem we are unsure where to find the power flow (pf) over the dc line. As far as I understand in most when using the ext2int function the dcline is modeled as two generators that are appended to the generator list in mpc_int.gen. After the run mdo.flow(i).mpc.dcline seems to show the initial value of the dcline but not the output for the ith interval. When I look in mdo.flow(i).mpc.gen(end-1:end,:) I can see the PG for the two artificial generators that represent the dcline. Also it seems that there is a -Inf and Inf set for PMIN and PMAX for one of the generators which results in a large PG output for the specific generator. I have the following questions: Where can I get the power flow (pf) of the dcline for each interval in most? How to make sure that both generators that represent the dcline are restricted to the specified PMAX and PMIN? Thanks for your help. Best, Kaspar
