Power quality standards for utility wind and solar power plants

Power quality standards exist to guide the interconnection requirements of large wind and solar plants. IEEE guidelines exist for flicker and harmonics, while IEC guidelines exist for the measurement criteria of power quality phenomena and the characterization of wind turbine equipment. There are also some uniform guidelines for low voltage ride through (LVRT) of large plants. The presentation gives an overview of these standard and requirements, and also suggests some application guidelines not covered in the standards themselves.
