Abstract

As the proportion of photovoltaic, wind power and other new energy in the power system gradually increases, the proportion of conventional power supply gradually decreases, therefore, the overall inertia of the system decreases，and the primary frequency modulation capability of the system gradually weakens. This paper mainly studies how to set the system control gain in the future low inertia system dominated by photovoltaic. Firstly, the proportion of photovoltaic, the inertia time constant of the system and the parameters of the saturation link should be considered, then the influence of changing the three factors on the frequency changing rate of the system is analyzed by simulation; then combined with the actual power system requirements, the best system control gain value can be obtained by taking the system frequency change rate as the objective function and using PSO optimization algorithm through simulation analysis.
