The invention discloses a system and method for multi-energy convergence coordinated control. The system for multi-energy convergence coordinated control comprises a direct current bus, a first alternating current/direct current converter, a second alternating current/direct current converter, a bi-directional direct current/ direct current converter, a third alternating current/direct current converter, a coordinating controller, a current/voltage detection device, a direct current/direct current converter capable of being externally connected with a direct-current load, and a direct current/alternating current converter capable of being externally connected with an alternating current load, wherein the coordinating controller can be used for receiving data information transmitted by the current/voltage detection device to generate corresponding voltage control signals and transmits the signals respectively to the corresponding first alternating current/direct current converter, the second alternating current/direct current converter, the bi-directional direct current/ direct current converter, the third alternating current/direct current converter, the direct current/direct current converter and the direct current/alternating current converter. The system and method for multi-energy convergence coordinated control can carry out convergence control on input multiple paths of alternating current/direct current power supplies, coordinates voltage conversion modules of the power supplies by utilizing the coordinating controller, adjusts the voltage method of the direct current bus, tracks the maximum power point of a photovoltaic array, and lowers operating cost.
