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.

Where is the Dongao microgrid built?

In China, the Dongao microgrid is built on an island in the South China Sea , which comprises an ESS of 500 kW, WTs of 750 kW, and a DE of 1 MW. A hierarchical control strategy is proposed to maintain the frequency stability on multiple time scales. The different types of island microgrids are summarized in Table 1.

What is the control system for the Nanji Island microgrid?

The control system for the Nanji Island microgrid is based on the IEC61850 standard , which coordinates the three control layers using an MMS protocol for between-layer communication and a GOOSE protocol for within-layer communication.

How can Island microgrids be managed optimally?

Overall, the paper presents a comprehensive approach to the optimal management of island microgrids. The approach involves reducing losses and pollution, and improving voltage while maximizing the use of renewable resources.

What is the Isle of Eigg microgrid project?

The Isle of Eigg microgrid project is built on an island located off the Scotland Coast , which includes 110 kW of hydro power, 24 kW of wind turbine (WT), and 32 kW of PV. A model of Eigg is created using HOMER software and assessed to ensure that it was a valid representation of the electrical network present on the island.
