Kaishan Island Microgrid Load

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.

Does Yongxing Island have a microgrid?

Moreover, the electric storage battery (ESB) is considered as a backup to enhance the resilience of the system. On this basis, the microgrid of Yongxing Island is considered by using the Hybrid Optimization Model for Multiple Energy Resources (HOMER Pro 3.14.2) software [ 34] (as shown in Fig. 2 ).

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.

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.

How much does the island microgrid system cost?

Total economic easement of the island microgrid system is illustrated in Table 5, which concentrates on the cost-effective economic assessment of the microgrid system. The total NPC of the system is around 50,30,362 $, which is calculated from HOMER optimization. The optimized operating cost is around 86,090 $/yr.

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.
