A new method for active power dispatch in wind farms

A new method for active power dispatch in wind farms is proposed to average the operating differences between wind turbines like startup/shutdown times and fatigues indexes, and increase the integration of wind power. To consider complicated factors like communication states and operating states, turbines are classified into different classes based on the real-T ime information. Then unit commitment for wind turbines (UCWT) is proposed with an objective function of minimizing the status changes and differences in startup/shutdown times to obtain the operating schedule. Furthermore, a non-linear optimization sub-problem with a goal of minimizing adjusting costs and averaging fatigue indexes is solved based on the operating schedule and the reference instructions for all turbines are calculated. Besides, an efficient solving algorithm is proposed to meet the needs of online applications. Multi-factors improved simultaneously. This is validated by the actual application in Inner Mongolia of China.
