Maldives multi-energy complementary intelligent microgrid project covers ADDU, Buruni, Kurendhoo, Goidhoo and Villingili five islands in Maldives, through intelligent distribution automation system to solve the energy supply problems on these five islands. In the project, SIFANG provided comprehensive solutions CSGC-3000 DMS/MGMS microgrid for integrated intelligent system based on joint power of 2.5MWp photovoltaic, 2.6MWp diesel generator set and 294KWh energy storage, which adopts advanced intelligent composite energy supply control system to real-time dynamically adjust synchronous output of solar photovoltaic system and diesel engine, and supports priority output of photovoltaic power generation, solves the problem of energy supply on five islands to the largest extent.
