Increasing wind penetration demands active frequency support from wind farms. This work integrates Wind Power Plant Control (WPPC) with Wind Farm Flow Control (WFFC) in a dynamic MATLAB/Simulink + FLORIS framework. New functionalities include: (1)Optimised wake-steering via geometrical linear relation to derive yaw setpoints; (2)Fast Frequency Reserve (FFR) and Frequency Containment Reserve (FCR) controllers tuned to Nordic SA requirements. A farm of four 15 MW IEA RWT turbines, aligned at 5D spacing, was simulated across various wind regimes, gusts, and yaw settings. Results: +3.11% farm power with optimised yaw; FFR and FCR met activation timing; performance limits observed near cut-in speeds. Integrated WPPC+WFFC increased reserves and improved reliability of frequency services.
