  "textContent": "When a frequency of an alternating current power grid has a first frequency, a grid-connected power converter adjusts an output power of a power conversion circuit from a preset reference power to a first power, where the first power is a sum of the preset reference power and a first inertia power. When the frequency of the alternating current power grid has a second frequency, the grid-connected power converter adjusts the output power of the power conversion circuit from the first power to a second power, where the second power is a sum of the first power and a first frequency regulation power, and an absolute value of a difference between the second frequency and a utility frequency of the alternating current power grid is greater than an absolute value of a difference between the first frequency and the utility frequency of the alternating current power grid.",
