Abstract :

In this paper, intifially an introduction is presented about Electric Power market in deregulated system and load shedding by interior-point method in these systems. Then, predictor-corrector of IPM is considered and by consideration of the IEEE 6 busbar network, distribution of load by using software (PSAT) will be considered. Then, with introduction of bilateral contracts in organized renewal system, the proposed method is applied to make optimal load shedding in the IEEE 30 busbar network. In this direction, the effective factors on changes of load- shedding model are analyzed completely. Some of factors are price changes, congestion lines (result from emitting of one or more lines) and maximum load-shedding limit in each bus bar.
