Adaptive Inertia Based on Secondary Control Strategy for VSGs with the SOC Constraint of DC-Side Energy Storage
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 …
