Current-Limiting VSG for Renewable Energy Applications
2021 IEEE 30th International Symposium on Industrial Electronics (ISIE), 2021 In this paper, an improved nonlinear controller structure, which inherits both virtual inertia (VI) and current-limiting properties in grid-connected voltage-source converters (VSCs), is proposed. The proposed method inherits the V dc ~ ω droop control for inertia emulation and frequency control, and Q ~ V droop control for AC voltage support.

State observer to improve the VSG control stability [PDF]
IECON 2020 The 46th Annual Conference of the IEEE Industrial Electronics Society, 2020 This paper proposes an observer-based current controller for a virtual synchronous generators (VSG) to improve its operational performances. First, the model and the controllers are analytically described. Two controller are compared to the proposed one (PI integrating a state observer): a traditional PI and a PI integrating virtual impedances for ...
