Multi-microgrid power supply system and control method

The invention discloses a multi-microgrid power supply system and control method. The system comprises a plurality of microgrids, mains supply can be in connection with each microgrid through mains switches, and each microgrid can comprises at least one renewable energy device, at least one energy storing device, at least one generating set and at least one load. The energy storing device can utilize renewable energy to generate electricity; the energy storing device can store power; the generating set can generate electricity; the load can consume power. Each renewable energy device, energy storing device, generating set and load can be in direct connection with the mains switches through microgrid switches. 本发明揭露种多微电网供电系统与控制方法，其可以包括复数个微电网，市电可以通过市电开关与各个微电网连接，各个微电网可以包括至少个再生能源装置、至少个储能装置、至少个发电装置及至少个负载。再生能源装置可以利用再生能源进行发电产生电力，储能装置可以储存电力，发电装置可以进行发电产生电力，负载可以消耗电力。其中，各个再生能源装置、储能装置、发电装置及负载可以分别通过微电网开关与市电开关直接连接。
