- The objective of the research is to compare between technique for determine the weak bus of the power system using static and dynamic contingency ranking analysis. Identification of the weak bus is very important for providing a proper control system to prevent for voltage collapse. Test system of this research is using the New England (IEEE 39 bus) power system. A severity ranking of the system is carried out on the study system to specify weak buses, in term of voltage instability. A contingency as a load increment is employed to examine the network buses condition and stability margin in the system. Three methods techniques as eigenvalue analysis of jacobian matrix is used as a static methods and a voltage collapse prediction index, and power transfer stability index as a dynamic methods are investigated. The result showed that the static analysis is giving more optimistic in evaluating loadability limit than dynamic. For the contingency ranking both static and dynamic give same trend in every bus. But for final decisions involving several consideration both planning and operation should be confirm by more accurate time domain simulation (dynamic) in which different characteristics of load, multiple controller, protection relays and coordinated them taken into account Key words: contingency analysis, static and dynamic analysis, voltage stability
