摘要：

Unified Power Flow Controller (UPFC) with the Virtual Synchronous Generator (VSG) provides additional inertia and damping to the grid, which improves the competitiveness of UPFC in the large-scale renewable energy power fields. However, the mismatched displacement angle of converters will increase the equipment costs and power losses. In this paper, a VSG applied to the UPFC was examined. The influence of the displacement angle on the power of UPFC-VSG was discussed, and then the parameter designing with the three existing displacement angle control schemes was analyzed. The parameter design optimization scheme with the minimum capacity and the displacement angle control strategy with the minimum loads under the limitations of the above parameters were studied in this paper. The relationship between the displacement angle, the voltage amplitude and the frequency was fitted into a mathematical function with the Statistical Product and Service Solutions (SPSS) in order to simplify the real-time calculations. The parameters of the additional BESS were designed as well. Finally, the comparison between the proposed improved scheme and the above-mentioned three typical displacement angle control strategies proves that the method proposed in this paper is able to further optimize the design parameters and the loading. © 2022, Power System Technology Press.
