Reliability Evaluation of Power Generation System with Wind Power and Reactive Power Balance
摘要
Abstract
The reliability evaluation model of wind farm is established.The influence of reactive power on the reliability assessment of power systems with wind farms is analyzed.The influence ofactive power shortage,reactive power shortage and voltage violation on power system reliability are introduced.Filtered by fault cutoff method,three stages of load-shedding strategies are adoptedin reliability analysis from both active and reactive power aspects.The third stage load shedding strategy has ability to determine the best location for reactive power compensation.The voltage violation can be reduced effectively by changingload shedding tolocal reactive power compensation.System reliability is analyzed based on maximum absorptive capacity of wind power integration.Calculation results on a 220 kV system validates proposed strategy.关键词
