计及风电间歇性的电力系统电压稳定评估（英文）

This paper proposes a simulation framework to evaluate the voltage stability of power system incorporating wind power intermittency. First of all, the modeling of power output of three types of wind turbines is discussed. Next, the Jensen model is employed to model the wind farm with wake effect taken into account. The Monte Carlo based technique is applied to conduct the voltage stability evaluation incorporating the randomness of wind speed based on the Weibull probability distribution. Furthermore, the relative sensitivity index is calculated to identify the weak buses during analysis. Finally, the case studies with different simulation scenarios are carried out. Some statistical results involving weakness probability, expected value and variance of relative sensitivity index as well as preliminary conclusions are drawn based on the numerical simulation results
