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 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.

Should res-based microgrid be built away from the mainland?

According to the above analysis, it is desirable to build an RES-based microgrid on the islands away from the mainland to effectively reduce the power generation cost, protect the environment, and increase the reliability of power supply. However, from the previous analysis, the following questions need to be discussed.

Is Microgrid technology a solution to the energy shortage?

A potential solution to the energy shortage or high energy cost in these islands is to increase the use of renewable energy to promote a sustainable development . The development of microgrid technology provides effective solutions to these problems.

How many island microgrid projects are there in the world?

There have been several island microgrid projects in the world. In Europe, the Kythnos Island microgrid project is built on an island located in the Aegean Sea , which includes 10 kW of PV, a 53 kWh battery bank, and a 5 kW diesel genset. This project aims to test the centralized and decentralized control strategies for islanding.
