Urgent: No
Sections: 2.1,, (new)
Description: This Protocol Revision Request (PRR) adds a requirement for wind generator control systems to be programmed to respond to frequency deviations by controlling WGR real power output in a way that is similar to governor response for conventional generators.
Reason: As WGRs displace more and more conventional generation, there will be a growing need for WGRs to replace the primary frequency response capability not being provided by the Off-line conventional generators. WGR primary frequency response shall be of particular value if frequency increases occur.
