Hybrid method to determine bus voltage and angle for line outage contingency evaluation

摘要

A unique method is presented which determines the bus voltage and angle at post-outage steady state, using an improved linearised load-flow method and the sensitivity relationship of the power system. This proposed noniterative method has been applied to 14- and 30-bus IEEE test systems. The results obtained are compared with the NR load-flow and the FDLF-compensation method, to show the effectiveness of this method.
