Congestion Management Based on Real Power Rescheduling Using Moth Flame Optimization

Congestion in transmission corridors is a major threat for power system operation. Proper and efficient congestion management initiatives must be adopted to mitigate congestion. This paper has chosen generator rescheduling strategy to manage the congestion. A technique of generator selection based on generator sensitivity factor has been introduced to identify the best generators for the real power rescheduling process. Further, a heuristic method named moth–flame optimization has been used to minimize the cost of real power rescheduling involved in congestion management. 39-bus test system based on the New England framework has been taken for validation of the proposed congestion management philosophy. The proposed strategy has been collated with the performance of other congestion management heuristic techniques and has proved to be efficient and robust.
