Hello Matpower users! I wonder if is possible to treat the thermal branch limits as a "soft" constraints in Matpower OPF procedures? For example, when I make some OPF calculations in order to determine effectivness of cross-border real power flow control by using phase shifting transformers, for some settings of PST, OPF don't converge. The main reason is that some branches have not enough capacity to transmit more power. Is there any simple way to overcome mentioned problem, for example, by automatic treatment the thermal limits of such branches not as a strict constraints, but as constraints that can be exceeded?
Best regards Roman
