Active optimization scheduling of wind farms based on wind turbine state evaluation

Measurement + Control
In response to the limited power operation mode of wind farms, an active power optimization scheduling method for wind farms is proposed based on the state evaluation of wind turbines. This method achieves optimal operational control of wind farms.
