CONTROL METHOD, LOAD AND POWER GRID SYSTEM

The present disclosure relates to a control method, a load and a power grid system. The method includes: detecting (S) a voltage change parameter on a power supply side; analyzing (S) a load control strategy corresponding to the voltage change parameter; controlling (S) an operation of the load according to the load control strategy. The solution solves the problem of inadequate communication facilities in the DC micro-grid, the DC home communication can be completed without or with less dedicated communication circuits, accordingly the system cost is reduced.
