Stochastic voltage-flicker power flow

A novel approach using the Y-matrix for analyzing voltage-flicker power flow is presented in this paper. Stochastic theory is incorporated with the power flow method to obtain the equivalent 10 Hz voltage fluctuation (/spl Delta/V/sub 10/) at each bus. The proposed method helps examine the impact of voltage flicker sources (e.g. arc furnaces) on system voltages. Simulation and experimental results show the applicability of the proposed method.
