Voltage Stability Assessment via Continuation Power Flow Method

This paper presents a potential algorithm for continuation power flow method in voltage stability assessment. Modified continuation power flow method termed as MCBF was developed which solved the solution of bifurcation point at the Q-V curve. The solvability of power flow at the bifurcation point beyond the maximum loadability point of a system was achieved through the implementation of predictor-corrector technique. QV curve was automatically plotted once the bifurcation point has been reached. Voltage stability analysis was subsequently conducted utilizing the MCPF solutions. Comparative studies performed with respect to the conventional power flow technique revealed the strength of the proposed MCPF; which was validated on a standard IEEE reliability test (RTS) system.
