Voltage Stability Assessment for Load-shedding Distribution

This paper started off with steady-state voltage stability analysis of IEEE-30 and IEEE-300 bus systems using different methods such as Newton-Raphson, Fast-Decoupled, Runge-Kutta, Iwamoto and Simple Robust method. Investigation on system voltage stability is then done using the Continuation Power Flow (CPF) method and modal analysis method. Simulation results showed that both methods are able to mitigate the shortfalls of conventional load flow method and are useful in determining the sequence and distribution of load-shedding for a system defense or load-shedding scheme.
