Abstract：The variability and uncertainty of wind power output bring great difficulty to the quantitative analysis of the operation characteristics for peak load regulation of power system integrated with high penetration of wind power. For the random nature of wind power， the paper establishes a peak load regulation capacity requirement model for wind power. Based on the peak load regulation capacity requirement model for wind power， a methodology for analyzing peak load regulation operation characteristics of power system with a high penetration of wind power is proposed. The methodology makes it possible to quantitatively analyze the influences of wind power integration on the peak load regulation capacity requirement and operation indices. The case studies were carried out for a system， and the results verified the effectiveness and accuracy of the presented model.

Key Words：Peak load regulation operation characteristics； Wind farm； Peak load regulation capacity requirement； Scenario reduction
