D5.3 Grid support services at the Iberian peninsula - Iberia case study

The Iberian case study in the REserviceS project has studied the provision of ancillary services from wind power and PV (variable generation). The case study informs about the services at the transmission level in a medium size power system with limited interconnection to the central European system. For frequency related ancillary services a unit commitment and dispatch model (WILMAR) was used to evaluate the economic benefits of having and using the capability from variable generation to provide frequency reserves. In addition, a set of one year of hourly dispatches was further evaluated in a frequency response model, which simulated a post-fault frequency response of the Iberian power system linked to the Central European power system. Existing studies on voltage control by wind power plants in Spain are also reported as evidence for provision of ancillary services for voltage management on transmission level.
