Abstract
Aiming at the new uncertainties brought by wind farms connected directly into power grid, a novel approach to calculate overload risk in grid-connected induction wind power system is proposed. In this method, the probability and consequence of line flow fluctuations is fully considered, and a probabilistic wind farm model is firstly presented. The probabilistic load flow (PLF) calculation with correlated parameters is then used to analyze the randomness of system statuses. Furthermore, the severity function is applied to describe the impact of line flow fluctuations. Finally, the overload risk index is quantified and is treated as an indicator of power system security. Simulation results of the modified 5-bus system confirm the effectiveness of the proposed method.
