• The integral term responds to the accumulation of past errors.

• The derivative term res...read more

The power curve of a Wind Energy Conversion System (WECS) shows the relationship between wind speed and power output.

• The power curve typically shows the rated power output at a certain wind speed, as well as the cut-in and cut-out speeds.

• It is important for optimizing the performance of the WECS and determining the best locations for installation.

• The shape of the power curve can vary depending on the type of wind turbi...read more
