Accurate modeling of stochastic wind power is one of the key links for peak load regulating operation and optimization in systems with large-scale wind power. According to the actual operation characteristics in China's power systems

the interactive characteristic indices considering the coupling between wind power and load are proposed

and a wind power output model based on peak load regulation problems is put forward. This model uses key and clustering scenarios to characterize the influence of wind power on the power system operation and peak demand. Afterwards

an operation optimization model for peak load regulation with large-scale wind power based on the wind power output model is established. The expected value of various operation indices through operation optimization in multiple scenarios is obtained

and the analysis on peak load regulating operation characteristics is comprehensively accomplished. A case analysis is made on a province in West China that verified the validity and practicality of the proposed method.
