Design of Controller for Virtual Synchronous Power Plant

The increasing participation of renewables in power systems has forced system operators to strengthen grid codes requiring renewable plants (RPPs) provide fast frequency support such as inertia response and oscillation damping. To cope with new requirements, this article proposes the implementation a virtual synchronous plant controller (VSPPC) for RPPs. VSPPC takes most from emulating behavior generator, especially case events, it permits provides damping capabilities. If compared conventional control schemes, main advantage lays fact that does not require implement any modification existing controllers plant's converters, which are often controlled grid-following generation units. This feature makes attractive incorporating advanced supporting functionalities utility-scale In work, principles behind comparative analysis based on simulation experimental results provided validate its performance.
