description With the gradual increases in the use of wind power and photovoltaic generation, the penetration rate of power electronics has increased in recent years. The inertia characteristics of power-electronic-based power sources are different from those of synchronous generators, making the evaluation of inertia difficult. In this paper, the inertia characteristics of power-electronic-based power sources are analyzed. A measurement-based inertia identification method for power-electronic-based power sources, as well as for high-power-electronic-penetrated power systems, is proposed by fitting the frequency and power data. The inertia characteristics of different control strategies and corresponding control parameters are discussed in a case study. It was proven that the inertia provided by power-electronic-based power sources can be much higher than that provided by a synchronous generator of the same capacity. It was also proven that the inertia provided by power-electronic-based power sources is not a constant value, but changes along with the output power of the sources.
