The virtual synchronous generator (VSG) can provide inertia to the system, and effectively support the system frequency. However, the VSG inertia setting is subject to the physical limitations of the DC side, which cannot be changed arbitrarily. Aimed at this deficiency, this paper proposes a VSG inertia adaptive control strategy based on hybrid energy storage …

Theoretical analysis and simulation test show that the transient process can be divided into three stages. In Stage 1, the main damage is caused by the high di/dt level to the power-electronic devices and the overcurrent to the DC cable. In Stage 2 and 3, the severe overcurrent occurs at the AC side, DC side and in the converter itself.
