Dear All, I was doing contingency screening research for a last half year using MATPOWER and only now decided to read the documentation to MATPOWER entirely. I was thinking that DCOPF takes into consideration line power flow limits (basically the difference between node angles). However it appears to me that these constraints are not considered. 1. Am I right? I don't think so. Perhaps you are not setting up correctly causing angle limits to be ignored? Please send a small reproducible example that we can take a look at. 2. Is there any easy way to include these constraints to DCOPF solver? I have read the section 6.1 but still confused - is there any examples of implementation? 3. Is there a way to make DCOPF solver to take into consideration N-1 security criteria? (i am currently interested only in line outages) You'll need to extend MatPower's DCOPF by introducing additional constraints, variables for the contingency cases. See the manual section on 'Extending the OPF'. Shri Thank you! Petya
