The invention provides a centralized generating set of a renewable energy source, comprising a main power supply, a plurality of auxiliary power supplies, an energy storing device and two DC (direct current) voltage buses, wherein an AC (alternating current) side of the main power supply (ZDY1) is connected with a power grid or an electro-load, and a DC side of the main power supply (ZDY1) is connected with a DCBus 1 (direct current bus 1) and a DCBus 2 (direct current bus 2); the output of each auxiliary power supply (FDY1...FDYn) is connected to the DCBus 1 and the DCBus 2; and an output or input end of the energy storing device (CNZZ1) is connected with the DCBus 1 and the DCBus 2. The centralized generating set can realize coordination control among distributed power supplies (namely various generating sets of renewable energy sources) without the electro-load, thereby adjusting output electric energy so as to meet demands of the power grid or the electro-load.
