  "textContent": "Embodiments of this application provide a power system and a control method. The power system includes a controller. The controller is configured to adjust an output current of a first converter to a first current value based on a voltage of a direct current bus and a voltage threshold, where a difference between an adjusted voltage of the direct current bus and the voltage threshold is less than a difference between the unadjusted voltage of the direct current bus and the voltage threshold. The controller is further configured to adjust the output current of the first converter to a second current value based on output power of the first converter and a power threshold, where a difference between adjusted output power of the first converter and the power threshold is less than a difference between the unadjusted output power of the first converter and the power threshold. The controller is further configured to adjust the output current of the first converter based on the first current value and the second current value. In this technical solution, the controller may adjust the output current of the converter in real time based on the first current value and the second current value, so as to adjust output power supplied to a power grid or a load and control a voltage of a bus not to exceed the voltage threshold. In this way, a direct current bus is stably controlled.",
