Maintaining the grid frequency stability while large amounts of low inertia generation is connected poses a significant control challenge. This presentation will give an overview of how an RTDS P-HiL test setup will be used to validate a wide area primary frequency response control system. The system comprises of distributed local controllers which rely on PMU measurements throughout the grid to provide fast and proportional frequency response depending on the severity and locality of disturbance. The response is provided though DERs with different response characteristics. A pre-deployment validation of this system will take place in the Power Networks Demonstration Centre, UK. This is achieved through the coupling of a physical 11kV distribution network (where the control system is installed) with a wider simulated UK grid model in RTDS. A comprehensive set of tests will be conducted to verify the dependability and security of the control system. Such tests include the introduction of local and remote disturbances, running through frequency and voltage profiles and an assessment of the impact of communication network performance on the control system.
