Abstract:

Microgrid power supply is taken by distribution systems in remote areas of Hainan. Using the abundant renewable resources , and considering the cost of reconstruction, seamless switch of operation modefrom offgrid to gridconnectedis realized, which provide uninterrupted power to local residents reliably. The operation mode and control principle of microgrid are introduced. The reforming program that switches regional microgrid from offgrid to gridconnected is represented from system working principle and breakerreforming.
