Dear all,
im working on a security constrained optimal power flow. At the moment I am using add_userfunction to add constraints, which include the outage of generator and branches. My problem is the adding of non-linear constraints. Because I can only add linear constraints I am working with real power and I am neglecting the apparent power. Because of this effect I cant calculate the absolute workload of the remaining supplies. Is there any mathematic explanation why I cant add non-linear constraints? Kind regards, Janek Massmann
