Effect of Fluctuation of Wind Power Output on Power System Risk

Article Preview

Abstract:

With expansion of the scale of wind power used in grid, its impact on the power grid has become more and more apparent. Because of its characteristics of intermittency and randomness, it is necessary to study the effect of wind power fluctuation on power system risk. The large scale wind power farm is connected to the power grid, the influence of its output fluctuation on static security of power grids is studied in this paper, and corresponding evaluation risk index of the power grid security is built. A new type of power system analysis software (PSAT) is used for the simulation analysis, and the results show that output fluctuation of wind power has great influence on low voltage and overload risk of power system.
