A performance evaluation method for grid-forming photovoltaic inverter

The paper proposes a performance evaluation method for grid-forming photovoltaic inverter (GFPV) based on an entropy weight-TOPSIS model, aiming to provide a scientific and comprehensive evaluation system for such inverters. Firstly, the paper selects 4 key indicators—inertia support, reactive power control, grid short circuit ratio adaptability, and conversion efficiency—as part of the performance evaluation system for GFPV, and provides corresponding testing methods and quantitative indicators. Then, the measured data of GFPV are used to verify the model of the indicator evaluation system. Through quantitative comparative analysis of GFPV from different manufacturers, the effectiveness of the evaluation system model is demonstrated. This provides a theoretical basis and practical guidance for the further development and optimization of GFPV technology.
