Stochastic voltage-flicker power flow

A novel approach using the -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 ( 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.
