Year: 2024

Type: article

Abstract: The grid-forming photovoltaic system (GFM-PV) can actively build up voltage without relying on the grid and exhibit voltage source characteristics. This paper proposes a reactive power decoupling control strategy for the problem of active and reactive power coupling in GFM-PV. Firstly, this paper analyzes the coupling principle of the active power and the reactive power of the GFM-PV DC/AC converter and proposes the reactive power decoupling control strategy. Then, this paper studies the influence of the DC/AC converter key parameters on the power stability of GFM-PV based on impedance analysis. Finally, the controller hardware-in-the-loop (C-HIL) experiments verify the effectiveness of the control strategy proposed in this paper and the correctness of the theoretical analysis.
