PROJECT TITLE :

Toward Online Line Switching for Increasing Load Margins to Static Stability Limit

ABSTRACT:

A novel online line switching methodology for increasing load margins to static stability limit of a look-ahead power system is developed. A design goal of the methodology is to balance speed (for on-line computation) and effectiveness (for quality of line switching solutions). Rather than dealing with the combinatorial nature of line switching drawback, the proposed methodology employs the strategy of screening, ranking and identifying to find a group of high-quality solutions. The proposed methodology ensures the satisfaction of operational and engineering constraints of (look-ahead) post-switching power system. The proposed methodology conjointly determines multiple solutions of line switching for operators to settle on a desired one. The effectiveness of the net line switching methodology is evaluated on the IEEE 118-bus and a 1648-bus power systems with very promising results.
