A Novel Pre-synchronization Control Strategy for Virtual Synchronous Generator Based on NLADRC-PLL

2021 IEEE 4th International Electrical and Energy Conference (CIEEC), 2021
Due to the mismatched voltage amplitude, phase and frequency between virtual synchronous generator (VSG) and utility grid, there may exist significant impulse current when VSG connects to the gird through the point of common coupling (PCC). This paper designs a NLADRC-PLL and proposes a novel pre-synchronization control strategy to decrease the impulse

Multi-inverters Pre-synchronization VSG Control Strategy for the Microgrid System

2019 IEEE 4th International Future Energy Electronics Conference (IFEEC), 2019
In the microgrid, the virtual synchronous generator (VSG) technology can realize the friendly access of the distributed power supply and improve the stability of the power system. Especially for the multi-inverter micro-grid system, the inertia and the damping are important for the distributed generator (DG) system.

Pre-synchronization Control of Grid-connected Three-phase Inverters Based On the Characteristics of Synchronous Generators

2020 15th IEEE Conference on Industrial Electronics and Applications (ICIEA), 2020
A pre-synchronization control strategy for grid-connected three-phase inverters is proposed in this paper ,to solve the problem of slow response of the conventional synchronous unit containing a phase-locked loop (PLL), based on the synchronization principle between the synchronous generator (SG) terminal voltage and the grid voltage when there is no ...

VSG-VFOC Pre-Synchronization Control for Graceful Mode Transition of Inverter-Based AC Microgrid

2018 17th International Symposium on Distributed Computing and Applications for Business Engineering and Science (DCABES), 2018
This paper presents a novel virtual synchronous generator (VSG) based multi-loop control solution with the virtual flux oriented control (VFOC) aiming to efficiently manage the microgrids under dynamics. The pre-synchronization control aligned to the outer loop of such VSG-VFOC solution is investigated to ensure smooth microgrid operational transition ...
