Three representative island microgrids in the East China Sea are demonstrated. Key technologies such as control technology and energy management for island microgrids are studied. Renewable energy penetration is discussed for the design and operation of island microgrids.
Table 1. Summary of the island microgrids. Recently, three unique stand-alone microgrid projects have been built at Dongfushan Island, Nanji Island, and Beiji Island in the east China, with an aim to replace diesel with renewable energy to improve renewable energy utilization, enhance power supply reliability, and reduce power supply cost.
Three stand-alone island microgrids with distinctive features have been built and are operating normally, which are located in the Dongfushan, Beiji, and Nanji islands along the Zhejiang coast, as shown in Fig. 1. The three islands are about 40–80 km apart. Particularly, Dongfushan is the farthest eastern inhabited island in China.
Key technologies such as control technology and energy management for island microgrids are studied. Renewable energy penetration is discussed for the design and operation of island microgrids. The operation data for a year of the three island microgrids are analyzed from various aspects.
