The utility model provides a system for weakening the impact on a grid. The system comprises a plurality of intelligent sockets connected with electrical equipment and cell controllers connected with the intelligent sockets, wherein each intelligent socket comprises a receiving module for receiving an opening instruction, a first communication module, a first microprocessor and a relay; each receiving module is used for transmitting the received opening instruction to the corresponding cell controller through the corresponding first communication module; each first microprocessor is used for receiving an instruction allowing the opening, which is transmitted by the corresponding cell controller through the corresponding first communication module and controlling the corresponding relay to be connected so as to open the electrical equipment; each cell controller comprises a second communication module and a second microprocessor; and each second microprocessor is used for sorting the opening instructions received by the corresponding second communication module and sequentially returning the instruction allowing the opening to the corresponding intelligent sockets according to sequencing. According to the technical scheme implemented by the utility model, the impact on the grid due to central opening of a plurality of electrical equipment is weakened.
