Regulation and frequency response service capability of modern wind power plants

Wind speed variability generates the main challenges for grid integration of wind power. Worldwide, requirements governing generator connection to the transmission grid evolve as the modern energy industry continues to develop. With increased wind power penetration, wind power plants are required to provide grid support and control actions similar to conventional power plants. Dedicated control systems for wind power plants employing variable-speed wind turbines can provide advanced control features for the transmission network operator. The paper summarizes the control characteristics of a modern wind power plant. It identifies the capability of modern wind power plants to offer fast regulation and frequency response services. Advanced functionalities for regulation and response to grid disturbances are also addressed.
