Dear Prof. Ray, I have a question regarding LMP calculation during congestion. I ran OPF on the 34-node feeder distribution network, feeding from a single infinite generator of price 50€/ MWh. It did not converge due to voltage congestion, not thermal congestion (there is no line congestion). Then, I introduced load curtailment with a price of 100€/MWh. The OPF converged, and at the bus of load curtailment the price was 82€/MWh, although I was expecting it to be at least 100€/MWh. Do you think I have done something wrong? or is there an explanation why thermal congestion is different from voltage congestion?
Thank you very much. Ibtihal Abdelmotteleb PhD Student IIT, Comillias University Madrid, Spain
