The invention discloses an electric power collector system for an alternating-current and direct-current microgrid. The system comprises a power electronic solid-state module, a monitoring module, an information processing module, an intelligent control module, a communication module, an energy storage module and an electric energy interface module. The communication module and the electric energy interface module are respectively connected with the power electronic solid-state module; the intelligent control module, the monitoring module and the information processing module are respectively connected with the communication module; the other end of the monitoring module is connected with the information processing module. By adoption of the technical scheme, a structure and a control process of distributed power source access equipment are greatly simplified, energy exchange and grid connection of the microgrid and a power distribution network are managed in a unified manner by the electric power collector system, integral control is realized, faults and interference between the microgrid and the power distribution network can be isolated completely, and unified control of power quality is realized.
