Reliability Assessment of Interconnected Generation Systems Based on Hourly Wind Speed Probability Model

摘要

Hourly wind speed probability distribution models are established, and based on them, wind speed is sampled. Considering the output characteristics of different type wind turbines and the wake effects between wind turbines, wind farm output model is formulated. With IEEE-RTS 24-node case including wind farms, multi-area analysis method and sequential Monte Carlo simulation method are used to perform the reliability assessment of the interconnected generation systems incorporating wind power. This paper takes the sequential correlation of wind speed and load as well as the affection factors on wind farm output into fully account, therefore the reliability assessment of power system incorporating wind power is more objective and accurate.
