Effects of swing equation-based inertial response (SEBIR) control on penetration limits of non-synchronous generation in the GB power system

This paper investigates the limits to penetration levels of nonsynchronous generation (NSG) in a power system and how this may be increased. Reduced system inertia, arising from high penetrations of NSG, is one of the main issues that may increase the risk of system instability in various guises. Swing equation-based inertial response (SEBIR) control, often referred to using a variety of terms, is considered to be a potential solution that can enable converter-interfaced generation to support the system during and after disturbances. However, the effects of SEBIR on system operability and its ability to increase the NSG penetration limits and improve system strength under high NSG scenarios has not been fully investigated.
