6 FAQs about [Japan s isolated island microgrid]

What are the 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.

Do Island microgrids work in the East China Sea?

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.

Where are microgrids located in China?

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.

What power sources are in the Nanji Island microgrid?

The Nanji Island microgrid contains four types of power sources: wind power, solar power, DE, and energy storage. The lithium batteries have three operating modes: P/Q, constant V/F, and droop control. DEs have P-F and Q-V droop control modes. WTs, PV units, and super capacitors have P/Q operating mode only.

Which island microgrids are based on yearly operation data?

Specifically, the analysis of Dongfushan Island, Nanji Island, and Beiji Island is based on the yearly operation data of 2012, 2015, and 2015, respectively. Fig. 17 shows the detailed monthly data of the three island microgrids. The PV generation on Beiji Island is split into two parts, PV-actual and PV-other, as shown in Fig. 17 (c).

Are microgrid systems a good option for Islands?

With the technological advance and the declining comprehensive cost, the advantages of microgrid systems on islands will be increasingly pronounced. We acknowledge the financial supports from National Natural Science Foundation of China (51507094 and 51537003). Chris Marnay.
