摘要

The virtual inertia control (VIC) of converter-interfaced generations (CIGs), which is originally applied to provide inertia support, will also affect system rotor-angle stability. This chapter proposes to control the virtual inertia constants coordinately such that sufficient inertia support is achieved, and meanwhile, the small signal rotor-angle stability can be enhanced without applying damping control strategies. Numerical studies in the IEEE 68 bus system have demonstrated that the proposed control strategy is effective enough.
