Abstract

Abstract:

Traditional island power supply methods mostly use diesel generators to supply power off the grid by themselves or connect to the mainland to supply power via submarine cables.However,it pollutes the environment and is extremely costly.Although distributed power sources have been used in islands in recent years,most of them are isolated islands and off-grid.The stability and reliability of power supply are not good,and a reliable island power supply scheme is urgently needed.Based on this,this article adopts the islands and islands networking scheme,which includes the research of energy controllers and improved droop control of equipment and devices.They coordinate and cooperate with the distributed new energy power generation and fault handling between the islands,which greatly improve the reliability of island power supply.

Key words: off-grid power supply, networked power supply, droop control, reliability
