A new control scheme of DGs based on multi-agent technology is proposed. Under this scheme, DGs compensate the load fluctuation of the distribution system by their autonomous control, therefore, to improve the system reliability and demonstrate new technical advantages over the conventional system. The simulation results indicate the advantages of proposed scheme.
