Closed-loop control of power system transient stability(6):control location selection

Based on the requirements of real-time performance,a method of fast generator-shedding location selection is proposed to efficiently prevent instability. The generators of the leading stability-loss group are sorted according to the product of its signed kinetic energy and power angle to get the initial set of effective generator-shedding location. The final set is obtained by removing the passive stability-loss generators from the initial set according to the difference of equivalent mechanical power between before and after generator-shedding. Simulative results of IEEE 39-bus system and Sanhua interconnected system verify the effectiveness of the proposed method.
