ABSTRACT
Underfrequency load shedding is the last defensive line to maintain the safe operation of power system. Frequency stability refers to the ability of a power system to maintain frequency stability following a severe system disturbance. This results in a significant power imbalance between generation and load. The new method presented in this paper assumes the application of WAMS(wide area measurement system, WAMS) as a base for this successful implementation. Two-area systems frequency response model is studied. Power partition is significant to load shedding scheme under emergency situation. An adaptive load shedding method is designed based on this idea. This may make new method more suitable to interconnected multi-area power system. The simulation result show the analysis of two-area frequency response model is accurate and new load shedding method is more effective.
