Research and Demonstration Application of On-line monitoring and evaluation technology for primary frequency regulation in Renewable Energy Power Station

When the renewable energy power station is included, the primary frequency regulation(PFR) of the grid can make a big difference. New control methods are proposed to accommodate this difference.In this case,we propose an on-line monitoring and evaluation method which based on PMU dynamic data for PFR of renewable energy power station. Firstly, the characteristics of the PFR of the renewable energy power station are expounded. Secondly, quantitative evaluation indicators of PFR are proposed. Finally, the concrete implementation method and an application example are introduced. The method has been applied in practice and has obtained good application results.
