摘要
Abstract
To study the effect of the integration of renewable energyand ultra-high voltage(UHV)on the security and re?liability of power grid,a comprehensive assessment on the reliability and stability of a practical regional power grid in 2020 is conducted in this paper. Considering the probability models of renewable energy and UHV output,areliability assessment method based on Monte Carlo simulation is proposed,and the transient voltage stability recovery index is for?mulated based on the BPA simulation results. Using the improved Latin hypercube sampling,the static voltage stability margin index and weak buses are calculated by the improved continuation power flow method. The assessment result shows thatthisregional power grid has high reliability and satisfies the static voltage stability guideline requirement in 2020;moreover,the influences of the integration of renewable energyand UHV on the grid stability emerge gradually.关键词
