1. A control method, comprising:
obtaining a voltage change parameter on a power supply side;
analyzing a load control strategy corresponding to the voltage change parameter; and
controlling an operation of the load according to the load control strategy,
wherein the analyzing the load control strategy corresponding to the voltage change parameter comprises:
determining an operation interval corresponding to the voltage change parameter, wherein the operation interval is divided according to different proportional values of the rated voltage or different voltage differences of the rated voltage, and one operation interval corresponds to one load control strategy; and
determining the load control strategy corresponding to the operation interval.
